| 摘 要： | 目的]研究缩节胺（DPC）对棉属4大栽培种的化控效应.方法]用不同剂量缩节胺（0、21、42、63 g/hm2）对不同棉花栽培种海岛棉（Gossypium barbadenseL）新海32号、非洲棉（G.herbadense L.）草棉、亚洲棉（G.arboreum L.）中棉和陆地棉（G.hirsntumL.）新陆中48进行喷施,观察化控效果,分析其对DPC化控的敏感性.结果]喷施DPC对4大棉种均有显著的化控效果,表现为双向调节,二倍体棉种调节效应主要体现在植株横向抑制方面,四倍体棉种的调控效果表现较为复杂,与品种特性有关.结论]4大棉种对DPC化控的敏感度不同,非洲棉反应最敏感,陆地棉敏感度最弱.

| Abstract: | Objective] The aim was to study chemical control effects of mepiquat（DPC） on different cotton cultivated genus.Method] Different DPC doses （0,21,42,63 g/hm2） were sprayed on four cotton cultivated species（G.barbadense L.Xinhai No.32,G.herbadense L.Caomian,G.arboreum L.Zhongmian,G.hirsntum L.Xinluzhong 48）,and their sensitivity to DPC was analyzed.Result] Spraying DPC on four cotton genus showed a significant effect of two-way adjustment,for diploid cotton plants,the moderating effect was mainly on lateral inhibition while for tetraploid cotton plants,the regulatory effect was more complex,which was related with species characteristics.Conclusion]Sensitivity of four cotton genus to chemical control was different,African cotton was the most sensitive while the upland cotton was the weakest. |
