Studying the Azerbaijani barley accessions to drought Stress Induced by Polyethylene glycol (PEG)

Abstract

Population growth and climate change necessitate the expansion of agricultural products. Drought stress has a significant impact on crop growth as a result of global warming. Drought stress can occur at any stage of plants growth and reduce production. One of the most important crops with high resistance to environmental abiotic stresses is barley (Hordeum vulgare). In order to choose the best barley accessions resistance to drought stress, 8 barley genotypes with different levels of (PEG) 0, -3, -6 and -9 bar were tested in a randomized complete block design with three replications at Khazar University's Center for Cell Pathology Research laboratory in November 2022. Traits such as root length, coleoptile length, plumule length, weight dry matter, percentage and rate of germination were measured. Selected drought tolerance genotypes can be used in barley breeding programs.
