【摘要】 通过盆栽试验模拟干旱条件，在黄瓜整个生育期进行不同磁场处理方法，结果表明，黄瓜叶细胞膜相对透性，在磁环境条件下生长黄瓜＜磁场处理黄瓜种子＜磁化水灌溉黄瓜＜对照。且磁环境条件下生长黄瓜与正常生长黄瓜叶细胞膜相对透性很接近，说明受干旱危害后，细胞膜伤害程度较弱。因此，磁环境下生长黄瓜具有明显的抗干旱能力。由黄瓜叶组织含水量、自由水、束缚水测定结果显示，黄瓜叶组织含水量、自由水、束缚水随磁场强度的增强而增大，且在相同条件下，自由水和束缚水的比率为对照＞磁场处理。黄瓜叶组织水分含量的磁场效应皆为正值，随温度升高，磁场效应有增大的趋势，同时在干旱时，温度对黄瓜叶组织含水量、自由水有负影响。更多还原

【Abstract】 Pot experiments were conducted to simulate drought conditions for carrying out magnetic field treatment of relative permeability of plasma membrance in leaves of Titicum aestovum. In the case of magnetic environment, the growing cucumber was less than the cucumber seeds treated in magnetic field, being less than the control during the whole development and growth stage. The relative permeability of plasma membrance of growing cucumber in magnetic environment and the normal growing cucumber was very close to each other,thus, indicating that the injury of plasma membrance treated under drought stress was very slight so that the growing cucumber under the magnetic environment had an apparent ability to resist drought. The results from water content, free water and bound water in cucuber leaf tissues indicated that water content, free water and bound water in cucumber leaf tissues increased with the growth of magnetic strength. Under the same conditions, the ratio between free water and boudn water in the control was more than that in magnetic field treatment. The magnetic effect of water content in cucumber leaf tissues was the positive value. With the temperature risind, the effect of magnetic field tends to increase, and meanwhile in drought, temperature had negative effect upon water content and free water in cucumber leaf tissues.更多还原
