摘　　要：[目的]研究外源物质处理对烟叶内源激素含量的影响,为今后调控烟株内源激素含量和物质代谢情况奠定基础。[方法]通过水培试验研究外源物质对打顶后烟株叶片IAA、ZR、ABA和GA3含量的影响。[结果]打顶后使用Put和JA处理,增加了烟叶IAA和GA3含量的降低幅度,且Put的效果更明显;打顶后,烟叶ABA含量增加,喷施Put和JA后烟叶ABA含量进一步增加,且喷施JA处理效果更明显;打顶处理与其他处理相比,烟叶ZR含量增加,但增幅不大。[结论]外源物质可以调节打顶烟株内源激素的含量,且不同外源物质调节效果不同。[ Objective ] The aim was to study effects of exogenous plant growth regulators on the content of endogenous hormones in the leaves of flue-cured tobacco, and lay a foundation for regulating endogenous hormones content and material metabolism. [ Method] A water-culture experiment was conducted to study the effects of exogenous plant growth regulators on the content of IAA, ZR, ABA and GA3 in the leaves of flue-cured tobacco. [ Result ] Experimental results showed that the contents of IAA and GA3 decreased by topping and the decline rate increased after spraying Put and JA, the better effect was Put; after spraying Put and JA, there had an improvement in ABA content, the better effect was spraying JA; the ZR content also increased in some way, but the increasing rate was little. [ Conclusion] Exogenous substances can adjust endogenous hormones content in tobacco leaves after topping, different substances have various adjustment effects.
