摘　　要：以观赏凤梨"丹尼斯"为试材,研究了不同催花剂处理对观赏凤梨"丹尼斯"内源激素含量的影响。结果表明:不同催花剂处理后,"丹尼斯"凤梨植株体内的IAA含量呈下降趋势,ZRs含量呈增加趋势。说明催花剂能抑制内源IAA的产生,促进内源ZRs的产生。以乙炔气体饱和溶液处理效果最明显。Taking Guzmania ＇Denise＇ as test material,the effect of different flower induction on the metabolic hormones differentiation of Guzmania ＇Denise＇ were studied.The results showed that Guzmania ＇Denise＇ plants of different flower induction treatment on metabolic hormones were affected.Content of IAA decreased of ＇Denise＇,ZRs content increased of ＇Denise＇.Forcing agents that could inhibit endogenous IAA production,and promote the production of endogenous ZRs.Treatment effect of A1 was most obvious.
