| 摘 要： | 植物生长调节剂对烤烟内源激素以及烟碱、多酚含量的影响结果表明,植物生长调节剂GA、IAA、2,4-D不同程度地提高了内源GA、IAA含量,降低了内源ABA含量,其中外源GA、高浓度2,4-D处理效果较为明显;植物生长调节剂ABA较强地提高了内源ABA的含量,而降低了内源GA、IAA的含量,喷施高浓度ABA效果明显,在打顶后30d,内源ABA提高140%,而内源GA、内源IAA分别降低了61.9%、85.0%,内源GA在打顶后20d含量达到高峰,内源IAA、ABA在打顶后30d达到高峰。

| Abstract: | Effects of plant growth regulator on endogenous plant hormones,nicotine content,and polyphenolic compounds were studied.Results showed that the content of endogenous giberellins(GA),indole-3-acetic acid(IAA)increased while that of abscisic acid(ABA)decreased by spraying growth regulator GA,IAA,and 2,4-D,in which GA and high concentration of 2,4-D had more obvious effects.Growth regulator ABA increased the content of endogenous ABA to 140% but reduced that of endogenous GA,IAA to 61.9% and 85% respectively at 30 days after topping.Results also suggested that accumulation of endogenous GA reached its peak 20 days after topping and accumulation of endogenous ABA,IAA reached their peaks 30 days after the plant topping. |
