| 摘 要： | 以皖棉19 F1为材料，研究了叶面喷施辛酸甲酯、癸酸甲酯和6-苄基腺嘌呤（6-BA）对棉花去顶的影响。3种试剂均降低了棉花的株高，较高浓度处理提高了果枝数、单株结铃数、铃重及衣分，从而提高了产量;对棉花纤维的上半部长度和整齐度影响不大，但多数处理增加了麦克隆值，高浓度处理降低了比强度和伸长率，使棉花纤维品质下降。总体来看，适宜浓度的辛酸甲酯、癸酸甲酯和6-BA能在一定程度上代替人工打顶。

| Abstract: | Wanmian 19 F1 was used to study the effects of methyl octanoate,methyl decanoate and 6-BA on topping in cotton.All the three chemicals reduced plant height.The higher concentrations increased fruiting branches,bolls,boll weights and lint percentage,thus increased the yield of seed cotton and lint.The chemicals had little influence on fiber upper length and uniformity,but most of them increased micronaire.At higher concentrations they reduced fiber strength and elongation rate,and thus decreased fiber qualit... |
