Abstract

Reducing the load provides an increase in the yield of marketable cuttings from 8.0 thousand pieces/ha in control to 33.3-71.0 tousand pieces/ha. It has been established that a decrease in the load of the mother bush contributes to a significant improvement in the ratio of the size of conductive tissues to the diameter of the cutting from 70.4% in the control to 71.2-74.3%, which is an important indicator for further propagation of grapes. The regularity of the decrease in the load of mother plants with an increase in the quality indicators of the cutting was revealed, namely the content of NPK from 7.8% to 8.1-8.7%, carbohydrates from 17.6% to 22.45-23.28%, of which starch from 5.0% to 9-9.3%, disaccharides from 6.17% to 6.20-6.45%, monosaccharides from 6.43% to 7.22-7.33%. The increased content of nutrients in the cuttings, with their further use as vegetative seedlings, contributed to an increase in the rates of survival, growth and development of seedlings on the plantation. A significant increase in the yield of seedlings from 40.1% in the control to 46.1-53.9% was noted with a decrease in the load of bushes with shoots.
