Honey for rooting cuttings. Growth stimulants for cuttings

With the advent of spring, every summer resident is in a hurry to plant as many new plants as possible in his garden and vegetable garden. If your dacha neighbor finally shared with you a seedling that was your dream for a long time, and it forms roots poorly, use the tips experienced gardeners. natural stimulants root formations have powerful biological activity. They enhance cell division and accelerate their growth.

Such regulatory substances are called phytohormones and are referred to as biostimulants. By regulating all vital processes in the plant body, they help to significantly increase the growth process. To date, several varieties of stimulants are available to gardeners and gardeners - folk remedies containing phytohormones and artificially created substances that are plant analogues.

Natural folk stimulants means of root formation.

1. Willow. This tree is able to secrete juices that contain active stimulants for the growth of the root system of plants. Willow branches are placed in buckets of water. When it takes root, all the rods are removed, and the resulting liquid is used for hard-to-root cuttings. Poplar, wild rosemary and willow have the same effect.

2. Honey. Natural honey has a whole complex useful substances. It stimulates growth, has an antimicrobial, antiseptic, immunomodulatory effect necessary for rooting. In three liters of water, dilute 2 tablespoons of honey and place the cuttings so that they are more than half immersed in the liquid. It is enough to withstand the sprouts in this water for 12 hours.

3. Potato. Potatoes saturate the cuttings with starch, vitamins and other substances. To use the tubers as plant nutrition, you need to make a small incision where to place the cuttings. Remember to water your potatoes daily.

4. Aloe. Aloe juice (agave) causes active cell division, increases the immune and protective functions of plants. The root system will develop faster if a few drops from an aloe leaf are squeezed into the water with a cutting.

5. Yeast. The yeast solution is rich in vitamin B and phytonutrients necessary for root growth. Preparing the cuttings for planting, it is recommended to keep them for a day in 2 liters of water with 200 gr. yeast. Next, the cuttings are placed in clean water for further rooting. The rest of the yeast mixture should not be poured out, it's great organic fertilizer for flower beds or vegetable beds.

Use of growth regulators.

They help in rooting cuttings, enhancing growth, increasing the flowering period of indoor plants.

By stimulating the root system, stimulants will help cure weak and rejuvenate old plants.

They make it possible to get a more powerful horse system. Plants get the maximum of useful elements from the soil.

Increase resistance to diseases and pests.

They activate the hormonal and enzymatic systems, causing an increase in the vegetative mass.

Rooting stimulants have an indispensable effect, both for green and for stiff cuttings. Preparations general purpose also give good results. They are used for the fastest rooting and the formation of a more powerful root system. The cuttings are treated with stimulant powder mixed with charcoal and placed in a suitable container with water until the desired result is obtained.

Natural root stimulants have proven their effectiveness for many years of use. experienced gardeners and beginner gardeners. A strong and healthy root system makes plants more resistant to frost, sudden changes in temperature and increases survival rate during transplantation. Everyone can decide for himself - to use it chemical substances or listen to folk wisdom. Let your plants respond to your care with gratitude and give a rich, healthy harvest.

Do you have your own dacha, garden or vegetable garden? Please share this article with your gardening friends:

If there were no special preparations at hand to stimulate root formation (heteroauxin, rootin, epin, humate, etc.), then you can use folk remedies- natural stimulants for the formation of roots, which were also used by our grandmothers and great-grandmothers. These funds are no less active than purchased drugs, moreover, they are natural.

honey solution

Natural honey stimulates growth, as it contains biogenic stimulants, and also has antimicrobial and anti-inflammatory effects. Dissolve a teaspoon of honey without an apex in 1 liter of water. Keep the cuttings in the solution for 18-24 hours, then rinse with water and immediately plant in the ground or put in clean water before planting. Cuttings can be immersed in honey tincture completely.

A solution of aloe juice, honey and ash

Cut off 1-2 leaves of aloe, put in the refrigerator for a day or two, then squeeze the juice out of it. We make a solution: 150 g of settled or spring water, 2 teaspoons of aloe juice, 1 teaspoon of honey, 1 teaspoon wood ash. Mix everything and lower the lower sections of the cuttings into this solution for 6-12 hours. After that, the cuttings are planted in a container with prepared moist soil. From above, the container must be covered with a transparent bag, and it is removed when young leaves appear.

egg white solution

Pour the egg white with a glass of warm water, insist for a week, then dilute 1: 2 with water (1 part of the infusion, 2 water). The solution is ready, although the smell is not very pleasant. We water planted cuttings, seedlings, perennials or diseased specimens. The solution is excellent - even plants that do not show signs of life after 3-fold treatment come to life.

Yeast solution

Yeast 1 g (1/4 teaspoon) diluted well in a little warm water. Put the cuttings in the solution for a day. Then rinse them and plant them in prepared soil or put them in a jar of clean water, where they leave until planting.

willow infusion

A couple of sprigs of willow (willow) put in water for a week. Then they are taken out and the necessary cuttings are placed in this water until roots form. As the water evaporates, it is topped up.

Infusion of male fern

Leaves of male fern brew 10 liters of boiling water and leave for two days. This infusion not only stimulates the growth of roots, but also increases the tone of plants, their resistance to adverse natural factors.

Potato Nutrients

The potato tuber is perfect place for the transport of cuttings. To do this, cuts of the cutting are inserted into the tuber by 3-5 cm, i.e. on the cuttings on both sides put on a potato tuber. However, potato juice also stimulates root formation. It is enough to cut the potato tuber, insert the cuttings between the two halves, and in 2-3 weeks the cuttings will have good roots. So that the potatoes do not dry out, they need to be wrapped in a plastic bag or they will have to be sprayed from a spray bottle every day.

Rhodiola rosea

Dissolve 5 drops of Rhodiola rosea extract in 1 liter of water. The cuttings are kept in the solution for up to 2 days, then planted in the prepared soil.

Aloe juice (agave)

Aloe juice increases immunity, strengthens the defenses of plants, affects cell division, and promotes accelerated root formation. Dissolve 5-7 drops of aloe juice in 1 liter of water. The cuttings are kept in the solution for 18-24 hours, then planted in the prepared soil. This solution can then be watered indoor plants.

You can cut 1-2 leaves of aloe, put in the refrigerator for 5-7 days. Then take it out of the refrigerator, add water, leave for 2-3 days and the growth stimulator is ready. In this solution, you can soak the seeds before planting, water the planted seedlings, cuttings, freshly planted perennials, trees and shrubs, as well as indoor plants.

Nettle infusion

100 g of fresh nettle leaves are poured into 1 liter of water, insisted for a week. Cuttings, seeds are kept in solution for up to 12 hours, then planted. You can use dry leaves: 1 tablespoon per 1 liter of boiling water, leave for 3-5 days, then water the seedlings, cuttings, any plants.

Infusion of onion peel

100 g of onion peel pour 1 liter of boiling water, leave for 2 days. Dilute 1:3 (1 part infusion and 3 parts water). You can water cuttings, seedlings, transplanted plants with a solution.

Wood ash infusion

For 1 liter of water we take a tablespoon of wood ash. We lower the cuttings into the solution for a day, then we plant them in the prepared soil or put them in ordinary clean water.

Kornevin is a root formation stimulator based on indolylbutyric acid (IMA), belonging to the group of auxins. Unlike heteroauxin (indoleacetic acid), the acid "tail" of IBA is longer (on the left in the figure), which is due to the longer and milder action of root.

The sales preparation of root is a white, beige or pinkish mealy powder, in the center. Packaging - in bags of 4-5 g for indoor gardening, summer cottages and small individual plots or bags for use in large areas, on the right.

Advantages and disadvantages

The main advantages of root is affordability and the ability to prepare substitutes with your own hands, see below. The use of root for vegetative propagation cuttings will cost approx. 1 rub. on a plant. Another important advantage of the root is full compatibility with most agrochemicals and plant protection products. In a doubtful case, checking rootin for compatibility with another drug is also simple: mix 50 ml of both working solutions. No sediment - compatible.

Disadvantages - specificity of action (also see below); root is not suitable for all crops. Also, the requirements for dosage, methods of preparation, use and precautions when working with the drug are quite stringent, see below. A slight excess of the dosage or use for other purposes leads, on the contrary, to oppression and even death of the cutting. Therefore, root growth as a root growth stimulator can only be recommended to fairly attentive and accurate plant breeders.

Precautionary measures

Kornevin is a hazard class 3 substance, i.e. moderately dangerous. Root powder is volatile, so you can only work with it on outdoors, balcony, veranda or in a room with supply and exhaust ventilation. When working with root, you need to use PPE: latex gloves, a plastic apron or cape (raincoat), a petal respirator or a dry gauze bandage, glasses. If the drug is ingested, you need to take activated charcoal, 1 tablet per 12-15 kg of body weight, drink 4-5 glasses of water and consult a doctor. In case of contact with skin, rinse immediately with plenty of water. In case of contact with eyes, rinse thoroughly with clean water and seek medical advice.

Features of use

The root preparation should be stored in the dark in a tightly closed container. glassware out of the reach of children and pets. The expiration date indicated on the container is valid only for unopened packaging; working solution is stored no more than 12 hours. Therefore, it is necessary to dilute root (see below) immediately before use and it is highly desirable to purchase the drug in an amount only for the current treatment.

Story

Charles Darwin first suggested that plants produce substances that affect phototropism - attraction to light, he called them auxins. With the development of biochemistry, it became clear that auxins are a special group of phytohormones and their effect on plants is not limited to phototropism. The IMC was first isolated in Russia by N. N. Suvorov and his co-workers. The first industrial technology for the production of IMC was developed by the Japanese researchers Mayima and Hoshino in 1925. Later, also in Russia, F.N. Stepanov proposed a much cheaper method for the industrial production of IMC.

Composition, action and dosage

In addition to IMC (0.5% of the dry mass of the substance, or 5 g per 1 kg of commercial powder), the composition of the root contains macro- and microelements that promote root formation: potassium, phosphorus, manganese and molybdenum. Rootin is diluted simply: how many grams are in a bag, so much is needed for the usual tap water. It is also possible to pollinate the roots with a dry preparation, see below. The action of the root is based on the formation of an influx over the cut / fracture - callus; rootin as a phytohormone is predominantly a calorific agent. Sleeping buds awakened in the callus sprout roots much more intensively than on other parts of the cutting, which is clearly seen in Fig.

However, it is necessary to use the root with caution. If mother plant in itself, it is well cut (callus before rooting is small or not noticeable), rooting will only delay rooting. Left to track. rice. it can be seen that the bean stalk without IMC and root takes root and develops better. In this case, the rooting of strong cuttings from a strong healthy plant should be accelerated (if required) with heteroauxin, and the formation of roots on weak ones should be stimulated with epin.

Note: in general, root is not particularly recommended for cuttings herbaceous plants; in this case, its purpose is somewhat different, see below.

Cuttings from medium to low rooting plants (roses, hibiscus, indoor citrus and grapes, indoor pomegranate) together with root require, as a rule, the use of additional drugs; most often - specific to this species. For example, rose cuttings take root much better if root is used in combination with zircon, on the right in fig. In any case, 3-7 days after planting the rooted cutting, you need to give it phosphorus-potassium fertilizer so that the vigorously growing roots “suck” the callus into themselves, otherwise the seemingly completely accustomed cutting may rot. Do not rely on rich soil here, you need quickly digestible mineral fertilizers.

About cuttings of conifers

The most difficult cuttings are conifers. For them, phytohormones alone are not enough, a special cutting technique is needed. For example, how to plant cuttings at home blue spruce and juniper, see video:

Video: about breeding blue spruce and juniper cuttings

Coniferous cuttings make sense not only as a cost savings on planting material. The species in the list are selected because, grown from cuttings, these conifers can grow in pots in an apartment. You do not feel sorry for the Christmas trees, which are cut in masses under New Year? And so it will be its own, alive. Juniper not only exudes a large number of phytoncides that improve the air, but also gives "berries" (cones in a fleshy shell), which are widely used in the pharmacopoeia, for refining drinks, etc.

Note, on an unhealthy topic: Juniper "berries" perfectly absorb fusel oils, at the same time flavoring alcohol.

Indications for use

So, based on the properties and characteristics of the root, it is preferable to use it next. cases:

• For rooting cuttings, mostly lignified.
• To stimulate root growth in seedlings.
• To increase the yield of self-pollinated fruits and vegetables (for example, northern varieties of tomatoes) and fruit crops.
• To stimulate the formation of children in decorative bulbs.
• For enlargement and strengthening of tubers / rhizomes of ornamental (not food!) Plants and increase in the reserves of nutrients in them for the purpose of more successful wintering or reproduction by parts of tubers.
• To improve the survival rate of grafts.
• To save perishing valuable tuberous and rhizomatous plants, for example. orchids.

Note: it is pointless to treat seeds with root to increase germination, as is sometimes advised. IMC does not have a noticeable beneficial effect on seeds.

rooting

Root cuttings can be rooted dry and with a solution. The dry method (see below) is more effective, but requires a greater consumption of the drug and entails a greater risk of rotting of the cutting. It is used if cuttings of this type do not take root with a solution. The dry method is applicable after a rooting attempt with a solution if callus formation does not occur 1-2 weeks after treatment. For diagnosis, inspect the cutting under a magnifying glass: if at least tiny sagging is noticeable, continue rooting with the solution. Instructions for rooting woody cuttings with a root solution looks like the following. way:

1. Prepare a basic solution of root: 1 g of the drug per 1 liter of water, see above;
2. Cut off a stalk with 3-4 leaves;
3. The bottom sheet is cut off (do not tear off!) So that a piece of its petiole covers the leaf bud;
4. The section is dried with filter paper;
5. The stalk is dried in the shade with room temperature before the cessation of juice secretion (usually 1-4 hours);
6. The stalk is kept in the base solution of the root for 10-15 minutes, immersed along the petiole of the cut leaf. The solution should not cover the leaf bud!
7. While the stalk is standing in the solution, 5-7 activated charcoal tablets are crushed;
8. If rooting is in water, crushed coal is poured into it. For rooting in the soil, coal powder is mixed with it. The rooting substrate must be prepared in advance: calcined, treated with a biocide, etc. In both cases, a pinch of coal powder is left;
9. The stalk is removed from the solution and, while still wet, is “dipped” in crushed coal for disinfection. Coal powder for plants is the same as brilliant green, iodine or mercurochrome for us;
10. The stalk is placed / planted in a bowl for rooting;
11. If rooting is carried out in water, and the roots are not visible, after a week and, possibly, after another week, the tip of the cutting is examined under a magnifying glass (see above). If there are signs of callus formation (point swelling like awakening buds), the stalk is planted in a peat pot with greenhouse soil and a little daily (1-3 tablespoons) is watered. You can cover with a jar, which is removed for 10-20 minutes in the morning and evening for airing.

dry

For processing with dry rootstock, instead of soaking in the solution according to paragraph 6, the cutting is dipped in rootstock powder over the remainder of the last leaf (do not pollinate the bud!), see fig. Further, everything is according to the instructions, but paragraphs. 1 and 9 are excluded.

For seedlings

To enhance root growth, it is advisable to treat seedlings with root root in places north of the black earth belt in cool years, when planting in the ground has to be postponed so that the plants have time to develop properly during the shortened growing season due to the increased work of the roots. IN favorable years and in warm places, the root will only “pull” the nutrients received from the green mass into the roots, which will at least lead to a decrease in yield. In these cases, the seedlings are watered with a root solution of 20-50 ml (1-2 tablespoons) per plant 1-2 weeks after the first pick and 3-5 days before planting.

Kornevin and harvest

To increase the fruiting of fruit and vegetable, berry and fruit crops, a basic solution of root root is used for garden crops and shrubs and a double concentration (2 g of the drug) per 1 liter of water for trees. Weather conditions and limitations of productivity stimulation with root, depending on weather conditions, are the same as for seedlings, see above. Watering is carried out in the evening of a warm day after the leaves are completely unfolded for trees and bushes and at the beginning of the budding of plants in the garden. Tree and shrub crops should be quite healthy. Watering rates:

• Adult (stably fruiting tree) - 2-3 liters in a well-moistened near-stem circle.
• A young tree is the same, half the size.
• Adult bush - 0.35-0.5 liters per bush.
• Young bush - half as much.
• Garden crops - 0.1-0.2 liters per plant of the base solution (!).

Note: it is undesirable to water the food bulbs, root crops and potatoes with root crops, the crop will be skinny and “hairy”.

Flowers

Ornamental bulbous, tuberous and rhizomatous plants are prepared with the help of root for a successful wintering also in unfavorable years (see above). To vegetative propagation by underground parts - on the contrary, to favorable ones. Processing - soaking the planting material for 2-3 hours in the base solution. The bulbs are immersed in the solution with the bottom (dry pollination is highly undesirable); tubers and rhizomes are soaked completely submerged. After soaking, the treated planting material is rinsed in clean water and planted immediately.

Note: during the same time, cuttings of garden grapes are soaked in the base solution.

For vaccinations

An increase in the survival rate of grafts with root is possible in favorable years if grafting is done by budding. In this case, the calloforming properties of IMC are used. The vaccination, before bandaging (applying a bandage), is sprinkled with root. If the graft has taken root, the rest of the leaf cutting will protrude and fall off after 1-3 weeks. Suddenly wrinkled, dried up and pressed against the trunk (branch) of the rootstock - the grafting failed.

Saving the perishing

Resuscitation of withering indoor flowers with root is most often used for orchids that have become ill in too dry and warm rooms, but it is also effective for domestic seasonal plants depleted by the wrong content, for example, gloxinia and cyclamen. In the latter case, untimely grown leaves and roots are removed from the tuber / rhizome, the residue is allowed to rest, as it should be according to the rules of the culture of this species (a rest period is forcibly arranged), and then the planting material is soaked, as described above. The revival of dying orchids with rotten roots with a root solution is carried out after. instructions:

1. The plant is carefully removed from the substrate;
2. Clean and wash the root system, as in preparation for transplantation;
3. Remove old, weak and diseased leaves, leaving only young and healthy ones;
4. The roots are examined, all rotten ones are removed by “grabbing” at least 1.5-2 cm of a healthy root;
5. If the roots are completely rotted, they are all removed, leaving only the bottom of the plant and 1-2 of the freshest leaves;
6. The orchid is kept for 2-3 hours in a warm (24-27 degrees) dark place to dry the sections;
7. The bottom or root system is soaked in the base solution, as when rooting cuttings (see above), but its temperature should be 2-3 degrees higher than room temperature;
8. The plant is transferred to a container with water of the same temperature (slightly warmer than room temperature) and activated charcoal at the rate of 1 tablet per 1 liter of water. Water should not cover the leaf sinuses and get into them!
9. Dishes with a flower are wrapped in an opaque material and transferred to a warm, bright place, but not to direct sunlight;
10. The air around the plant is moistened 2-3 times a day with a spray gun, giving a foggy jet;
11. Water is added daily at a temperature also 2-3 degrees higher than room temperature instead of evaporated water;
12. If within 2-2.5 months. young roots appeared, resuscitation was successful, the patient will live. The plant can be planted in a suitable substrate.

Note: in the same way, accidentally broken plants with fragile stems can be brought back to life, for example. dracaena. The upper part with the crown is treated with root.

Substitutes

In many cases, for rooting cuttings (except, perhaps, coniferous ones), it is possible to replace the purchased root with biostimulants of root formation from natural products containing IMC:

• A teaspoon of honey is diluted in a liter of water. The cutting is kept in the solution for 10-12 hours, then planted in the ground. The rest of the solution is poured into the root hole.
• 100 g of baker's yeast are diluted in 1 liter of warm water. The cuttings are soaked in the solution for a day and planted in place.

The percentage of rooted cuttings after such treatment is lower than from root, but there is no danger of burning the cuttings with the drug. On the other hand, observations of the process of vegetative reproduction will provide experience that will allow a successful transition to the use of root and other strong biostimulants.

To increase the likelihood of rooting, to accelerate the formation of roots on the cuttings (especially difficult to root), to obtain a more powerful root system, it is recommended to treat the cuttings before planting with growth stimulants (phytohormones), which contribute to the beneficial accumulation of organic substances at the root formation site. For successful cuttings of woody plants, growth stimulants are often used:
- heteroauxin (fine crystalline powder of white, pink or yellowish color);
- beta-indolylbutyric acid (outwardly similar to heteroauxin);
- beta-indolylacetic acid and alpha-naphthylacetic acid (white or grayish powders).

Growth stimulants have a high biological activity, therefore, they are used in very small concentrations (according to the instructions). For processing cuttings with solutions growth promoters use glass, porcelain or enameled dishes. Processing of cuttings with growth stimulants is carried out in a darkened room at a temperature not exceeding 20-23 degrees (a higher temperature is dangerous, and at 28-30 degrees cuttings are poisoned).

Three methods of stimulating treatment of cuttings are most often used:
- immersion of the lower ends of the cuttings in aqueous solutions of stimulants (solutions of low, medium or high concentration are prepared);
- immersion of the lower ends of the cuttings in alcohol solutions of stimulants (used to treat cuttings of plants that cannot be in water for a long time, as well as to propagate rare and valuable plants);
- treatment of the lower ends of the cuttings with dry growth powder (a mixture of growth stimulant with talc or crushed charcoal, usually at the rate of 1-30 mg of the stimulant per 1 g of talc or coal).

Root formation of cuttings is even more enhanced when their lower ends are treated with a mixture of growth stimulant with vitamin C (ascorbic acid) or vitamin B1 (thiamine) before planting. Vitamins also contribute to faster growth of shoots in rooted cuttings (however, the use of vitamins alone to improve root formation and better growth shoots from cuttings, without the use of growth stimulants together with vitamins, does not give a positive effect). When preparing aqueous or alcoholic solutions of a growth stimulator, when preparing growth powder, one of the above vitamins is added to them, after dissolving its powder in a small amount of water. After preparing an alcohol solution of the stimulant, a vitamin is added to it at a concentration: vitamin C - 20-50 mg per 1 ml of 50% alcohol, vitamin B1 - 2-20 mg. When preparing growth powder, dissolved vitamin is added to it at the rate of: vitamin C - 50-100 mg per 1 g of talc or coal, vitamin B1 - 5-10 mg per 1 g.

A freshly prepared growth stimulator solution, together with a vitamin solution added to it, is used immediately after cutting the cuttings; the depth of immersion in the growth stimulant solution depends on the length of the cuttings and the degree of their lignification. Green cuttings are immersed in a solution of 2-4 cm (no deeper than a third of the length) and kept in it from 10 hours to a day (according to instructions); processing time depends on the concentration of the solution and the type of stimulant. The small length and the presence of leaves in green cuttings contribute to enhanced absorption of the stimulant by the cuttings along with water. Lignified cuttings are immersed in the solution for half or two-thirds of the length of the cutting.

In growth powder, prepared in advance for processing cuttings before planting by dry method, the content of the growth stimulator can vary considerably (depending on the desired activity of the stimulator). To prepare growth powder, the stimulant is first dissolved in water, and then this aqueous solution is thoroughly mixed with talc or coal and a vitamin solution. The resulting mixture is dried in a dark place at a temperature of 50-70 degrees; the powder is stored in a tightly closed opaque container. To process the cutting, its lower part is moistened with water, powdered with growth powder and planted immediately.

Amateur gardeners often use when rooting cuttings as growth stimulants "Epin", "Kornevin", "Sodium Humate", "Zircon", aloe juice. Also, seeds and corms, delenki are soaked in growth stimulants before planting. perennials. The Epin solution has proven itself very well as a natural bioregulator when used for spraying to maintain plant immunity during rooting, before and after picking seedlings and under stressful growing conditions.

I bought cuttings of new grape varieties and I want to grow seedlings from them. What kind of root formation stimulators can be used in order for the cuttings to take root better?

Nikolay KOVALENKO,

Kremenchug

root growth stimulants Lately are gaining more and more popularity. They are successfully used in viticulture to improve rooting when propagated by cuttings. The characteristic functions of this category of substances are the stimulation of the formation and growth of roots. Root regulators are biologically active substances and therefore require very careful handling. An overdose of these compounds is very dangerous: not only can you not get the expected effect, but you can also face the exact opposite result.

The processing of cuttings or roots of seedlings must be carried out using personal protective equipment. While working with stimulants, it is not recommended to smoke, drink, eat food. Wash your face and hands with soap after work. It is necessary to store all preparations to stimulate root formation in a dry, cool room away from food products and medicines, out of the reach of children and pets. When buying rooting stimulants, you need to check their expiration dates.

The most common used are the following preparations that stimulate the formation of roots: heteroauxin, root, zircon, humisol, sodium humate.

The most common root stimulant is heteroauxin (indolyl-3-acetic acid). This substance has a high physiological activity. Available in the form of tablets that are not toxic, but have bad smell. They are highly soluble in alcohol, but poorly in water. Therefore, to obtain a solution of heteroauxin, it is better to initially dissolve it in alcohol, for these purposes ethyl, formic alcohols can be used, and then the prepared alcohol solution is mixed with water to the required concentration. Decomposes quickly in the light. The optimal concentration of the solution is considered to be a 0.02% solution, it is recommended to soak the cuttings for 18-24 hours, immersed in 2/3 of their length, while the upper part of the cutting with an eye should remain above the solution. To increase the effectiveness of heteroauxin when rooting cuttings, treatment of cuttings with zircon (1 ampoule per 10 liter of water) and heteroauxin (200 mg per 1 liter of water) can be combined.

Kornevin - an analogue of heteroauxin, is a powdering composition. Root formation on cuttings is greatly facilitated in the case of the use of this stimulant for the formation and growth of roots. The active substance of this drug, 4-(indol-3-yl)butyric acid (IMA), in the plant gradually turns into the phytohormone heteroauxin, providing the best effect, including a milder and longer-lasting effect at the lowest doses compared to other auxins. In addition, the use of root in the form of a powdering composition makes it possible, due to its good adhesion to the surface of the cuttings, to activate the penetration of the active substance into the plant cells, significantly increase the efficiency and simplify the technology of using the drug. Before treatment with this drug, the cuttings are immersed in water for several hours. Slightly damp cuttings are then immersed with the lower end in the powder contained in the bag for about 1 cm. The cuttings are then planted in moist soil or substrate without excess water. On average, 0.1-0.3 g of root is consumed per cutting. You can soak the cuttings in the working solution of this drug, as well as in a solution of heteroauxin for 18-24 hours.

A good stimulator of root formation is zircon. It is obtained from vegetable raw materials - echinacea purpurea. The active substance is hydroxycinnamic acids. The solution is packaged in polypropylene ampoules. The drug stimulates the formation of roots during the rooting of cuttings, if the cuttings are soaked before planting in a working solution of 1 ml per 10 liters of water for 14 hours. Significantly increases the effectiveness of its action when mixed with heteroauxin (200 ml per 1 liter of water) during joint processing.

Good results in improving the rooting of cuttings are given by the use of Humisol. It is a brown liquid high content humic substances, odorless. Contains in a dissolved and physiologically active state all components of biohumus: humates, amino acids, vitamins, natural phytohormones, micro and macro elements, spores soil microorganisms. Humosol stimulates root formation. To do this, grape cuttings for 2/3 of the length are soaked for a day in a solution of humisol with a concentration of 1:25.

An effective tool that stimulates the formation of roots on cuttings is sodium humate. Its active ingredient is sodium salts of humic acids. It is a soluble powder or dark colored tablets. The drug stimulates the biochemical processes occurring in the process of root growth. Use for soaking the cuttings a solution of sodium humate at a concentration of 3-5 g (1 teaspoon) per 10 liters of water. Humates are harmless to human health, do not accumulate in plants, do not contain weed seeds and pathogens.

For a long time, bee flower honey has been used as a natural stimulant for the formation of roots on grape cuttings - this is the nectar of flowers processed by bees. Pure flower honey contains more grape and fruit sugar and less reed. Contains a number of enzymes and vitamins B, PP, C, K, E, ascorbic acid, 35 minerals and other elements.

In flower honey there are so-called biogenic stimulants, as well as growth substances (bioses). Therefore, grape cuttings treated with a solution of honey take root well. As a survival stimulator, we use honey in concentration: one tablespoon (no more) per bucket of water. Honey is pre-dissolved in warm water. Soaking time - 2 days. Cuttings in a solution of honey can be immersed completely. Honey produced by bees from sugar is unsuitable for soaking cuttings.
