Comparison of osmotic regulation and antioxidation between sorghum and maize seedlings under soil drought stress and water recovering conditions
干旱胁迫与复水条件下高粱、玉米苗期渗透调节及抗氧化比较研究

The results from pot experiment showed that the drought(tolerance) mechanism of osmotic regulation and(antioxidation) was all found in sorghum (and) maize seedlings.The drought tolerance of sorghum is stronger than that of (maize,) its leaf relative water content and water potential are higher under drought (condition.) The main osmotic regulation substances in sorghum are soluble sugar and protein,catalase(CAT) is used as the main antioxidant enzyme.K~ and(proline) are the main osmotic regulation substances and the main antioxidant enzymes are superoxide dismutase(SOD) and peroxidase(POD) in maize.
