INFLUENCE OF NEGATIVE TEMPERATURES ON THE GROWTH-REGULATING ABILITY OF AQUEOUS SOLU-TIONS OF CARBOXYMETYLED PLANT RAW MATERIAL
UDC 630*861
Abstract
The results of studies on the effect of negative temperatures (the process of freezing - defrosting) on aqueous solutions of preparations obtained by carboxymethylation of waste products from the processing of plant materials (oat flower films, buckwheat husks, poplar leaf litter) are presented. The purpose of this paper is to study the effect of storage conditions of solutions of carboxymethylated plant materials at low temperatures on their growth-regulating properties. The properties of aqueous solutions of carboxymethylated sunflower husks, oat flowering films, poplar leaf litter with a two-fold freeze-thawing cycle for defining growth-regulating ability were studied.
It was established that all the studied samples retain their growth-regulating ability with respect to Ivory oats and Omskaya 36 wheat. Freezing and thawing processes enhance their growth-regulating effect. The studied biological products can increase seed germination and enhance the growth processes of the studied crops. For oats, the germination rate increased by 5–10%, the length of the root increased by 1.6–3.2 times, and the stem by 2.5–4.8 times as compared with the control. For wheat, the germination rate increased by 10–18%, the root length increased by 1.5–2.9 times, and the stem by 2.0–4.8 times as compared with the control.
