Abstract

The invention relates to agriculture, namely to viticulture. The purpose of the invention is to increase the multiplication factor and increase survival rate. The method involves connecting the driver with an oblique copulation stock and closing the inoculation with a cover made of plastic film with subsequent dressing. As a stock, they use an annual matured stem, and a lead - a one-eyed cutting grown in vitro. Before grafting, the rootstock is subjected to stratification at a temperature of 28 - 30 s and a relative humidity of 98 - 100% for 10 - 14 days. For the best: survival, copulation cuts of the inoculative components are fused with an antiseptic solution before joining to the vaccine. After all the operations have been done, the vaccinations stratified in the light with an intensity of 2-5 thousand k, 1 tab. With S (L

about:

The invention relates to agriculture, namely to viticulture, and can be used in nursery farming to propagate valuable and scarce grape varieties by grafting.

The purpose of the invention is to increase the multiplication factor and increase survival rate.

Example. The deficient or grape varieties are propagated by growing from isolated tissues in a sterile culture, which are then cut into one-eye cuttings with a leaf before inoculation, so that the lower section is slanting and located 1-1.5 cm from the leaf. These cuttings are used as grafts,

As a stock, a variety of Berlandieri-Riparia Kober 5BB is used, from which standard-sized cuttings are cut from one-year-old ripe shoots.

Before grafting, mature cuttings are kept in the thermostat for 10-14 days at a temperature of 28-30 and relative

transverse sections and splicing of grafting components are planted in a greenhouse and germinated to obtain standard graft seedlings,

As a result of experiments conducted on grafts Magarach № 65274-30, performed on the stock of Berlandierich X. Riparia Kober 5BB, as well as varieties

Ukraine on a stock: Riparia x Rupestris 101-14, it was found that with the proposed method of reproduction from each plant grown in vitro, during the vegetative period, about 10 phylloxer-resistant grafted grapes can be obtained. The best results are obtained under the conditions of pre-production preparation of cuttings of the stock, treatment of copulative slices, their stratification and cultivation.

The survival rate of grapes by the proposed method and the known is shown in the table.
