金丝小枣插条中外源激素与内源激素的关系

该文从生理生化的角度对外源生长素（ＮＡＡ）在金丝小枣嫩枝插穗中的作用进行了研究。实验结果表明，外源生长素（ＮＡＡ）影响插条内的生理生化反应，大大提高了插条内源生长素（ＩＡＡ）的含量，同时能够维持内源脱落酸（ＡＢＡ）含量保持在一定的水平，调节了内源激素ＩＡＡ和ＡＢＡ两者之间的动态平衡，使得ＩＡＡ／ＡＢＡ值保持基本稳定；说明两者之间有着一定的协调作用，内源ＩＡＡ很大程序上影响形成层处细胞，使其分化出根原始细胞。

Study on Exogenous and Endogenous Hormone in Cuttings of Z.jujuba Mill cv. Jinsixiaozao

The role of exogenous applied auxin(NAA) in root cuttings of Z.jujuba Millcv. Jinsixiaozao green branches has been studied in the article through physiological method. The result shows that the exogenous applied auxin(NAA)has influence on the physiologicalreaction of cuttings,It greatly enhances the content of endogenous auxin(IAA),maintainsthe content of endogenous bascisic acid(ABA),regulates the balance between endogenousauxin and endogenous abscisic acid,stabilizes the proportion of endogenous auxin to endote- nous abscisic acid;Meanwhile exogenous applied(NAA ) influences the cells in cambiumgreatly,and stimulates these cells to differentiate into root primordium initials.
