ВЛИЯНИЕ ЭКСТРАКТА ИЗ JUNIPERUS SABINA L. НА МОБИЛИЗАЦИЮ РЕЗЕРВНЫХ ВЕЩЕСТВ И КРАХМАЛА ПРИ ПРОРАСТАНИИ СЕМЯН КУКУРУЗЫ

Abstract

Starch is considered the main reserve substance of corn seeds. The purpose of our research was to study the effect of a natural growth regulator isolated from the aerial part of Juniperus sabina L. (JS) on the mobilization of reserve substances and starch from corn seeds during germination. Treatment of corn seeds before germination with diluted solutions Științe Biologie și ecologie of JS extract to a concentration of 0.001% and 0.0001% contributed to both an increase in the overall germination of seeds and an increase in the length of roots and the proportion of reserve substances used for their growth. The initial starch content in the seeds of the corn hybrid P427 averaged 71.67±1.66%, and during germination of intact seeds, about 6-7% of starch is mobilized. Treatment with JS solutions at various concentrations (0.1...0.0001%) increased the consumption of starch used for germination of corn seeds by 9.39-12.92%. A direct correlation has been shown between the amount of mobilized starch and metabolic efficiency.
