Реакция на засуху различных линий армянской кукурузы в зависимости от почвенно-климатических условий
Keywords:
maize, drought, water potential, osmotic pressure, soil and climatic conditions
Abstract
The article describes the reaction to the drought by the kinematic profiles of four lines of maize with contrast sensitivity to the stress-factor depending on the soil and climatic conditions together with the control inbred line B73. It was noted that drought resistance strongly reduced leaf growth parameters, including the rate of elongation and the final length of the fifth leaf. It was determined that the phenotypic differences between lines differing in geographic origin (Armenian samples and B73) and tolerance to drought can be identified in the seedling stage by measuring the total length, osmotic pressure values and the water potential of the fifth maize leaf.
