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.

Highlights

Polymeric super absorbents are a class of polymeric materials that can absorb and retain large amounts of water and aqueous solutions
Under the adaptation conditions to non-sterile conditions of test-tube grape microplants, the influence of the water-retaining agent Aquasin added to the substrate on the survival rate of plants was not established
The addition of super absorbent to the soil substrate has a positive effect on plant growth and development

Summary

Introduction

Polymeric super absorbents are a class of polymeric materials that can absorb and retain large amounts of water and aqueous solutions. They consist of three-dimensional polymer networks that do not dissolve in water but swell significantly in an aqueous medium. Agriculture is one of the most important sectors of the national economy. This is due to the ever-increasing demand for food products caused by the growing population. The property of super absorbents to preserve and, if necessary, to release moisture and fertilizers in the soil for plants is the most important for agriculture [3]
