【摘要】 以黄栌 (PistaciachinensisBunge .)、紫荆 (CercischinensisBunge .)为材料 ,研究了两园林绿化树种在不同盐浓度胁迫下的生理反应。结果表明 ,细胞膜透性、可溶性糖随盐分浓度的增大而升高 ,而脯氨酸、可溶性蛋白的变化则无明显规律 ,因此前两者是植物在盐胁迫条件下较为稳定的生理生化指标 ,可用于抗盐性评价 ,而脯氨酸、可溶性蛋白只能将其作为一种辅助性参考指标。更多还原

【Abstract】 Four physiological responses to salt stress treatments are tested and analysized in seedling leaves of Pistacia chinensis Bunge.and Cercis chinensis Bunge. The membrane permeability and the soluble sugar content are increased as the increase of the salt concentrations.However,the same trends are not found in the amount of the proline and soluble protein . As a result, both the membrane permeability and the soluble sugar are reliable indices in evaluation of salt tolerance in woody plants.更多还原
