Abstract

The invention relates to viticulture. The purpose of the invention is to improve vaccination intergrowth by the prolonged action of a growth promoter. When grafting onto a pin, which is used as a piece of wood, is carried out by soaking the rootstock and privot in a 0.02% aqueous solution of heteroauxin. The graft is soaked for 1 day, and the stock - 4 days. Simultaneously with them, but with a 0.2% solution of heteroauxin, the pin is soaked for 6 hours. All components are then combined into a graft. Foamed polystyrene or compacted titanium powder is used as a porous material to form the pin. 1 hp ff, 1 tab.

Description

The invention relates to agriculture, in particular to the propagation of grapes by grafting.

The purpose of the invention is to improve intergrowth by the prolonged action of a growth promoter.

Example. A batch of ripened, standard in diameter, single-eye grafts of grafted and blinded grafts of grape varieties and pins from air-dried wood of the following sizes are prepared: length 25-30 mm, cross-section 1, 5x 1, 5 mm.

The cuttings of the graft and stock are rolled up until they are fully saturated in a 0.02% aqueous heteroauxin solution. To do this, according to the method in grape nursery

The cuttings are soaked in solution for 1 day, and the cuttings - 4 days.

Concurrently held over. 6 h soaking the pins in the following variants: in water, as well as in a 0.2% aqueous solution of heteroauxin. The optimal concentration of an aqueous solution of heteroauxin (0.2%) is determined according to preliminary experiments, where it varies from 0.02 to 0.5%. When soaking the pins in aqueous solutions of heteroauxin with a concentration of 0.02 and 0.5%, the yield of standard seedlings does not differ much from the variant with soaking the pins in water. In the first case, this is due to the insufficient concentration of the stimulator in the solution, and in the second case

with its inhibitory effect on growth processes.

A total of 200 vaccinations were made for each of these options. To do this, transverse copulation cuts are made on the cuttings: on the cuttings - at a distance of 15 mm from the node diaphragm located at the level of the base of the eye, and on the cuttings - at a distance of 40 cm from the lower node of the vine, used for soil climatic zones of Ukraine. When performing vaccinations, saturated with water or 0.2% heteroauxin aqueous solution, the pins are introduced first into the core, up to the stop in the diaphragm, and then into the core, until the cuttings are in contact with copulative slices. The YEUTS obtained in this way are protected with polyethylene heat-shrinkable moisture insulating coatings 101CIMI and installed in a stratification chamber with a temperature of 28-30 ° C on a water layer. After stratification, grafts are planted and the shkolka and seedlings are grown from them.

For control in the same way; .1 grafts are completed using an air-dry pin and soaking the grafts of the graft and the stock in water or in a 0.02% aqueous solution of heteroauxin.

The table shows the results of grafting grapes on wood pins (Aligote to Kober 5BB in the foothill Magarach trial estate) The use of the proposed grafting method provides (see table) an increase in the yield of standard seedlings compared with the known methods from 17-32 to 55-66% i.e. more than 2 times, while the pins for grafting can be made of various porous materials: foamed polystyrene, compacted titanium powder and other materials non-soil for the plant.

The proposed method provides a significant improvement in the water supply of the cutting stem, thanks to the fact that such a pin not only does not absorb moisture from adjacent tissues, but also works like a wick through the capillaries.

the moisture rises (is drawn) into the graft from the sub, immersed in water in the stratification of the grafts, even in case of a breakdown of direct contact between the copulation surfaces of the cuttings. Thus, the proposed method allows even before physiological accretion of the grafting components to completely supply the transplant graft with water due to the stock, which is well supplied with moisture during graft stratification on the water layer. Furthermore, evaporation of moisture from the pin pores creates a high humidity between the graft and the flow that favors callus formation and accretion of vaccination. A further increase in the yield of standard seedlings by the proposed method is provided by impregnating the shift with a growth stimulator, which is used as an O, 2% aqueous solution of heteroxy-α.

on. At the same time, the duration of the stimulator is significantly prolonged (high concentration with gradual expenditure) and growth processes are accelerated at all stages of growing seedlings.
