摘　　要： 烟株打顶后喷施赤霉素(GA3)对烟叶生理特性及产量和质量的影响研究结果表明,GA3能使烟草叶片的长、宽度及水分含量增加,并能降低叶片的叶绿素含量和栅栏组织厚度,以及降低叶片厚度和叶面密度,使烟叶的产量提高、烟碱含量减少。 The effect of GA3 application after topping on physiological characters, production and quality of tobacco leaf were studied. The results showed that after GA3 application the length and width of tobacco leaf increased, chlorophyll concentration reduced, moisture increased, thickness of palisade tissue and leaf reduced, and leaf density decreased, the content of nicotine in the tobacco leaf reduced, thus the yield and quality of the tobacco leaf were improved.
