摘  要:
为探讨在土壤逐渐干旱胁迫过程中,长寿花生理生化特性与抗旱性的关系,选取相对含水量、膜透性、可溶性糖和脯氨酸4项指标,研究了其动态变化规律。结果表明土壤干旱胁迫下,与对照相比,相对含水量下降,膜透性、可溶性糖和脯氨酸上升。

摘  要:
The four physiological indexes in Kalanchoe blossfediana including RWC,membrane permeability,content of proline and soluble sugar were chosen to investigate the relashionship between the physiological characteristics under gradual drought stress of soil.The results showed that the RWC decreased under drought stress,while membrane permeability and the content of proline and soluble sugar increased.The membrane permeability and the content of proline and soluble sugar of Kalanchoe blossfediana leaves were significantly higher than those of the control under serious stress.
