Abstract

The article discusses the effect of a cross-linked copolymer of potassium and ammonium salts of acrylic acid “Aquasin” on in vitro revitalized grape plants when adapting to non-sterile conditions and growing completion before planting in open ground. The research was carried out on the basis of VNIIViV named after Ya.I. Potapenko on the indigenous Don variety Krasnostop Zolotovsky and the indigenous Crimean variety Kandavasta. The aim of the study was to study the usage effectiveness of super absorbents (hydrogels) for the post vitro stage. As a result, the positive effect of adding the water-retaining agent Aquasin to the substrate on the growth and development of plants was noted. This was especially reflected in such indicators as ripening and the shoots’ diameter. In addition, the possibility of preliminary saturation of the super absorbent with immunostimulants or fertilizers is of interest.
