摘　　要：用离体叶片的保水率、电导、水势、脯氨酸含量及根冠比对６个玉米品种苗期抗旱性进行初步研究，用五级评分法对各项指标的测定值进行定量表示，经过权重分配进行了抗旱性的综合评价。Preliminary studies on drought resistance identification of six maize varieties were made by testing water conservation ability of isolated leaves, membrane permeability, water potential, free proline content and root-cap ratio. Quantitation description of the tesing resuit was expresed in five level grade method.
