　　为了解大叶铁线莲对水分胁迫的反应和适应性，研究了干旱和水涝胁迫下大叶铁线莲的生理指标变化。结果表明：水分饱和亏缺、质膜相对透性、丙二醛、可溶性蛋白、可溶性糖含量及抗氧化保护酶中的SOD、CAT 活性，随胁迫时间的增加呈上升趋势；叶绿素含量、相对含水量、保护酶系统中的POD活性呈下降趋势，说明大叶铁线莲对水分胁迫具有较强的忍耐能力，且忍耐水涝能力高于耐干旱能力。

To understand the response & adaptability of Clematis heracleifolia under water stress ,the variation of physiological & biochemical indexes of Clematis heracleifolia were studied by experiments of simulating water stress .Result shows that the relative water deficit (RWD) ,plasma membrane permeability ,MDA ,soluble protein , soluble sugar contents ,SOD ,CAT increase with the increase of water stress .The content of chlorophyll ,RWC &POD decrease then .It indicates that Clematis heracleifolia have stronger endurance under water stress ,and its anti-waterlogging capabilities are stronger than drought-tolerant capability .
