摘　　要：用表高油菜素内酯 (epihomoBR)浸种可以提高玉米幼苗的抗旱性。在干旱条件下 ,经epihomoBR处理的幼苗叶片内超氧化物歧化酶活性、过氧化氢酶活性及脯氨酸含量都提高 ;丙二醛及相对电导率都降低 ;Using epihomobrassinolide to soak maize seeds could enhance the drought resistance of maize seedlings. Under the condition of water stress, in seedlings treated by epihomobrassinolide the activities of superoxide dismutase and catalase increased, proline content rised while malonaldehyde content and the relative conductivity decreased;the photosynthesis rate increased too.
