摘要： 用0.01 mol/L CaCl2浸种和喷叶的棉花幼苗，在土壤干旱条件下，叶片水势、叶绿素含量、光合速率、呼吸速率、SOD和CAT活性降低幅度低于对照；MDA含量和细胞质膜相对透性增加幅度显著低于对照。
Abstract: The reduction of relative water potential (ΨW) of cotton seedling leaf were retarded and the cotton drought resistance was improved obviously by seed immersion in 0.01 mol/L CaC12 solution and spraying the leaves of cotton with the same solution under drought soil condition. The decrease ranges of the chlorophyll content, photosynthetic rate, respiratory rate and of the activities of superoxide dismutase (SOD) and Catalase (CAT) were less than those of the control. The increase ranges of malonadehyde (MDA) content and the relative cell membrane permeabihty were lower than those of the control. The results showed that seed immersion in and spraying leaf with CaCl2 solution can increase the ability of moisture conservation and various phsiological activities in the cotton leaf.
