CREATION AND INTRODUCTION OF HIGHLY EFFECTIVE ANALOGUES OF NATURAL PHYTOHORMONES OF PLANTS GROWTH FOR INCREASE OF AGRICULTURAL CROPS

Abstract

Synthesis o f new potential plant growth regulators (analogues o f natural photohormones) was carried out by stirring of equimolar mixture of aryloxypropyne with 1 -methylpiperidine-4-one — in lerns of Favorski reaction. New derivatives o f acetylene amino alcohols series ZhoT have been produced. The most efficient preparations ZhOT-4 and ZhOT-7 have been selected by screening their water-soluble forms on seeds o f wheat and barley, whose biometric parameters exceed those o f the control and standards — known phytohormones such as heteroauxin (indolyl-3-acetic acid), 6-BAP (6-benzylaminopurine) to run further tests. Detailed laboratory and demonstration comparative tests have shown a high efficiency o f new preparations ZhOT-4 and ZhOT-7, which exceeded the indicators of the reference preparation Agrostimulin (Ukraine).
