ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of continuous dry-stress and full-water treatments in different periods of spring on the water condition, permeability of plasma membrane and protective enzymes activities in leaves of Ligusticum chuanxiong.</p><p><b>METHOD</b>Pot cultivation method was applied and physical and biochemical indexes were measured.</p><p><b>RESULT</b>Under dry-stress treatment the soil relative water content (SRWC) and the relative water content (RWC) in leaves decreased gradually with the days of treatment increased, the content of malondialdephyde (MDA) and permeability of plasma membrane increased significantly. The activities of superoxide dismutase (SOD) and catalase (CAT) increased at first and then decreased while the activity of peroxidase (POD) increased. The influence of full-water treatment to all above indexes was the same trend with that of dry-stress treatment approximately but was not significant.</p><p><b>CONCLUSION</b>In this experiment, the suitable soil relative water content for growth of Chuanxiong is about 60%.</p>
