Assessment of interspecies drought resistance of Elytrigia at the seedling stage

Abstract

Abstract: The drought resistance of 10 species of Elytrigia, collected from six countries, was identified and evaluated using simulated drought stress and rewatering in a green house at the seedling stage. The relative water content of leaves (RWC), relative electrical conductivity rate (REC), free proline accumulation (Pro), contents of malondialdehyde (MDA) and the soluble sugar content (SSC) were measured at 0 (CK), 7, 14, 21, 28, and 35 days of drought stress and 7 days after rewatering. Their average survival rates (ASR) after 35 days of drought stress followed by the rewatering were calculated. The three drought resistant classes: high drought resistance (ET001, EPU02, EJ003 and EH001), medium drought resistance (ES001, EE013 and EC002) and weak drought resistance (ER037, EL001 and EI022) were classified using the above 5 physiological indexes by the Euclidean distance clustering method.
