Influence of Growth Stimulators on the Yield and Quality of Hybrid Grape Seedlings When Growing Them in Greenhouses

Abstract

This research work presents the results of studying the effect of growth stimulants on the regeneration processes of hybrid seedlings of grapes when they are grown in a greenhouse in vessels on a substrate peat + soil + sand (1: 1: 1). As a result of this work, it was found that the highest yield of seedlings, 85% and 81%, was observed when using drugs Kornevin and Double roots. And the least yield of seedlings was in the control variant, on the soil of 27%. At the same time, the best option for the quality of seedlings is the length of the main shoot of the seedlings, the internode diameter between the 2 and 3 eyes, the number of roots and their weight was in the version using Kornevin and amounted to 366 cm, 6 mm, 23 pcs. and 258 gr. Plants in the control variant on the soil substrate had the least development.

The use of Albit in the technology of growing grafted seedlings of technical grape variety

“…The output of grafted seedlings, depending on the affinity of the scion-rootstock combination and production technology, is low. Often, the low final yield of seedlings from the nursery garden is associated with insufficient fusion of the grafting components during the stratification period and a deficiency of nutrients during the growing season in the nursery garden, which can be provided by foliar application of phytohormones or modern fertilizers and complex growth stimulants [2][3][4][5][6][7][8].…”
