3 maize varieties which are different in drought resistance were used as materials and 26%PEG(4000) was used to induce water-stress in this experiment. The changes of plant morphology, physiological and biochemical characters and their relationship to varieties drought resistance were studied under water-stress. The result showed:
1. Under water-stress the growth of plant was restrained. The plant height declined obviously, and leaf area, accumulation of dry matter were restrained in...
