摘　　要：研究了不同浓度Ｓ３３０７对雪松、桧柏、龙柏插枝生根的效应，通过与ＰＰ３３３，ＮＡＡ等药剂处理的比较，证明Ｓ３３０７促进插枝生根的高效性及其与ＮＡＡ互作的加成效应。试验结果还进一步证实，Ｓ３３０７可通过抑制插枝中ＧＡｓ的生物合成，提高插枝基部多酚氧化酶活性，降低ＩＡＡ氧化酶活性，改变内源抑制物质和生长物质的比例，从而促进了树木的插枝生根效应。This paper is a study on the effects of S 3307 of different densities on the rooting of the cuttings of cedrus deodara loud,sabina chinensis L.Ant and S. chinensis L. Ant cv. kaizuca. comparing with NAA,PP 333,the authors have demanstrated the high effectiveness of S 3307 and its additional effect with NAA.The result has also proved that through inhibiting the biosynthesis of GAs,S 3307 can improve the activity of polyphenol oxidase,and reduce the activity of IAA oxidase.Through changing the propotion of intrinsic inhibitors and growth substances,it promotes the rooting of tree cuttings.
