摘　　要：通过研究8个玉米自交系在干旱胁迫条件下的生理变化,认为干旱胁迫能够增加玉米自交系的脯氨酸含量,提高电导率,不同自交系之间的脯氨酸含量、电导率差异较大.SOD酶和POD酶活性在干旱胁迫条件下也增强,但是自交系之间变化不大.The experiment was carried out in eight maize inbred lines,and the results show that proline content and electric conductivity were increased in drought stress.There are different proline content and elec- tric conductivity in different maize inbred lines during formal case and drought stress.SOD and POD activities increased in drought stress and had no obvious distinct in maize inbred lines.
