| 摘 要： | 选用两种熟性不同的棉花品种,在北疆比较其棉铃发育及适应性,结果表明:特早熟品种新陆早10号和新陆早13号棉铃生长发育快,蕾铃多,但蕾铃脱落率较高,植株自下而上果枝第一果节棉铃发育所需积温逐渐减少;早中熟品种中棉所35号和冀棉668生育期较长,比特早熟棉长7～8 d,棉铃的成铃率较高,单株平均成铃数也比早熟棉多1.2～2.5个,中部和下部棉铃发育所需积温变化不大,但自上部第6果枝棉铃发育所需积温明显减少.

| Abstract: | The different maturity genotype cotton varieties including two early - mature and two mid - early-mature varieties were selected to study their rules of boll growth and development in the North Xinjiang.The result showed that Xinluzao No.10 and Xinluzao No.13 belonged to early - mature genotype.The developmental speed of bud and boll is higher,the number of bud and boll is more,but abscission rate of the bud is also higher.Effective accumulated temperature of the first boll development gradually decreases from lower branches to the upper ones in early- mature varieties.The growth period of Mid - early maturing varieties,Zhongmiansuo No.35 and Jimian No.668,is 7-8 days longer than that of early - mature varieties.The percentage of fruiting bolls of the Mid - early - mature varieties is higher than early - mature varieties,and the number of fruiting bolls is 1.2-2.5 more than that of early - mature varieyies.Effective accumulated temperature of the boll development is equilibrium from lower to middle in early - mid - mature varieties,but distinctly decreasing from the sixth fruit branch to the upper ones. |
