摘　　要：干旱胁迫下冬小麦幼苗细胞膜透性的变化与品种的抗旱性强弱有关．严重干旱胁迫下，抗旱性较强品种的细胞膜透性小于抗旱性较弱的品种，在干旱胁迫初期抗旱性较强品种的细胞膜透性大于抗旱性较弱的品种．在持续干旱胁迫的整个动态过程中，细胞膜相对渗漏的变异系数越小品种的抗旱性就越强．The permeabitity of cell membrane of winter wheat seedlings was related to drought resistance of the varieties.At the begining of drought stress the cell membrane of the drought resistant varieties permeate more electrolyte than that of droughe susceptible does.But as the estess was intensifiled the cell membrane of the drought susceptible.During the drought stress,the less vari ation of relative permeability the more drought resistence have.
