The drought resistance of 14 germplasm of Psathyrostachys juncea at seedling stage was comprehensively identified and evaluated using the simulating drought stress and rewatering method in green house. The morphological and physiological indexes were measured and analyzed. The results showed that: along with the drought stress increasing, the relative water content and chlorophyll content in leaf were decreased; meanwhile, the relative electrical conductivity rate, content of MDA and free proline ac...
