Влияние брассиностероидов на амилолитическую активность ферментов при прорастании семян различных генотипов ячменя

Abstract

The influence of plant growth regulators - epibrassinolide and homobrassinolid - on changing the activity of a- and 0-amylases during seeds germination of two grades of barley and their isoplasmatic lines is shown. Epibrassinolide increased the activity of enzymes during 48 hours. Homobrassinolid increased the activity of amylases in Roland grade during all the experiment, Zazersky grade being not susceptible to treatment of this compound. The more sensitive grade of Roland proved to vary the enzyme activity in a wider range that of Zazersky.
