当植物处于干旱、盐碱或低温等不利环境条件下,质膜通透性的变化是较早出现的生理伤害症状,测定相对电导率是反映质膜通透性变化的常用方法。植物在逆境下累积游离脯氨酸,其含量的变化与逆境下植物体内水分和物质代谢关系甚为密切。在抗旱
When plants are exposed to adverse environmental conditions such as drought, salinity or low temperature, the permeability of the plasma membrane is an early physiological injury symptom. The relative conductivity measured is a common method to reflect the changes of plasma membrane permeability. Plant accumulation of free proline under adverse conditions, its content changes with the plant under adverse environmental water and material metabolism is closely related. In drought
