| 玉米赤霉烯酮浇根处理可促进棉花早现蕾。内源激素检测表明，外施玉米霉烯酮能够增加细胞分裂素含量，降低脱落酸含量。玉米赤霉烯酮能够促进棉花提早现蕾可能与其提高花芽分化期细胞分裂素含量，降低脱落酸含量，改变了棉花发育过程中内源激素平衡有关。 |

| The Influence of Exogenous ZEN on the Flower Bud Differentiation in Cotton |
|
|
|
| Abstract: |
| Using the cultivar Zhongmian 12 of cotton as the experiment material, the treatment with exogenous zearalenone (ZEN) could accelerate the rate of flower bud appearance, increase the content of CTK, decrease the content of ABA, and advance the peak appearance of CTK. This result indicated that the influence of ZEN on flower differentiation was perhaps completed by changing the balance of endogenous hormones. |
