ПРИЖИВАЕМОСТЬ И КИНЕТИКА РОСТОВЫХ ПРОЦЕССОВ РАЗЛИЧНОГО ТИПА МИКРОЧЕРЕНКОВ ВИНОГРАДА IN VITRO

Abstract

New data on the peculiarities of the growth and development of plants of the Mahrovatchik and Belobulaniy grape varieties during subcultiva-tion, depending on the location of donor micro-gears on the shoot, are presented. There are 3 types of micro gears:type 1−1–4 micro gears from the lower part of the shoot, type 2 –from the middle part, 5−8 from the base of the shoot; type 3 − from the upper part of the shoot, 9−12 from the base of the shoot. When cultivated in conditions of high temperature and low humidi-ty, the best development was noted in the plants of the Mahrovatchik variety formed from the eyes of the middle part of the shoot. Inhibi-tion of shoot growth and higher plant viability during the entire cultivation period allows us to consider type 1 (bottom) of micro-gears optimal for laying a collection, and micro-gears of the upper and middle part of the shoot to be used for mass reproduction of the Belobulaniy varie-ty. The high regenerative ability of the ripened micro-gears of the Cabernet Sauvignon variety has been proven.
