Relationship between permeability of cell membrane of winter wheat seedlings and drought resistance

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.
