Abstract:Siberian wildrye (Elymus sibiricus) is a xero-mesophytic forage grass with high nutritional quality and stress tolerance. Among its numerous germplasm resources, some possess superior drought resistance. In this study, we investigated the physiological differences between drought-tolerant genotype (DT) and drought-sensitive genotype (DS) leaves under drought stress. The results showed that under drought stress, DT maintained a lower leaf water potential for water absorption, sustained higher photosynthetic eff… Show more
