SU736926A1 - Method of stratification of grapevine grafts - Google Patents

Description

I

The invention relates to the field of viticulture and can be used in agriculture.

There is a method of grafting grape grafts under greenhouse conditions in a moisture-holding material (fur) at a temperature of 22-25 ° C before the formation of callus 1.

The disadvantage of this method is that with a lack of moisture, the vaccinations dry up at high temperatures, and therefore either do not form a callus at all, or give it a very weak influx, quickly covered with a plug, which interferes with splicing. When the interlaying material is excessively wetted to the adhesion site, the access of oxygen to the air is difficult, which leads to the appearance of mold and lead plant growth.

There is also a known method of grafting grafts in which the basal portion of grafts is immersed in water to a depth of 3-5 cm. The process of stratification lasts up to 20 days 2.

However, with this method, the roots on the submerged parts of the grafts are not always formed. Water has a musty smell. A delay in the basal portion of vaccinations in water for more than 20 days leads to the loss of the ability of rootstock formation from

plots of the stock, which during the stratification was submerged in water.

Vaccinations may be stratified before landing on a splinter. 5 The purpose of the present invention is to increase the yield of standard seedlings by retaining the root-viability of the grafts. This goal is achieved by the fact that

Period 10 of stratification is periodically drained over a period of two months.

It is preferable to drain the water for the period of the night. Example. Grape stratification

15 grafts are carried out in drawers, at the bottom of which there is an opening for periodic flooding of the basal part of grafts to a depth of 3-5 cm. To protect the grafts from drying out, the bottom of the boxes are lined with water-retaining material - filterboard. During the stratification period, water is released at night. In the morning the crates are poured again with water. The remaining procedures are carried out according to known methods.

25 The proposed method has the following advantages: it extends the period of graft stratification in water to two months by reducing the green grafts with an appropriate moisture regime and
