EFFECT OF A POLYMER SUPERABSORBENT "AQUASIN" ON GROWTH AND DEVELOPMENT OF HEALTHY PARENT VINE

Abstract

The article considers the effect of cross-linked copolymer of potassium and ammonium salts of acrylic acid "Aquasin" on in vitro healthy parent vine plants in open ground conditions. The research was carried out on the basis of Nizhnekundryuchensk department of experi-mental field of Potapenko Institute on native Don variety Krasnostop Zolotovsky. The pur-pose of the work was to study the feasibility of using hydrogel at the stage of planting vegeta-tive healthy grape plants in the open ground in sandy soils. At the same time, the effectiveness of its use at different stages of plant prepara-tion was evaluated – the superabsorbent was added directly when planting the basic parent vine plantation in open ground and the afteref-fect of the introduced absorbent was noted at the stage of adaptation of in vitro plants to non-sterile conditions. As a result, it was noted that the hydrogel added at the adaptation stage contributes to better survival and preservation of plants during the first two years of growing in the open ground. The addition of hydrogel directly during planting in the open ground en-sures better plant development during further operation of the parent vine plantation.
