棉花的生长、开花、结铃的减慢与蕾铃脱铃有关。棉铃荷重影响棉铃脱落可能是通过激素起作用的。本实验试图验证这样的假设,即棉铃产生脱落酸并运往果枝生长点在那里抑制生长、开花和结铃。摘除果枝第一节的花或幼铃并不能减少果枝及第二果节离区脱落酸含量,对第二果节棉铃中脱落酸含量的影响是不定的。在一个大田试验中。摘除一些果枝第一节位的棉铃,第二果节棉铃脱落酸含量随着不断摘铃而下降。因此,这种效应是累积性的,不限于单个果枝。摘除第一果枝的花或铃使第二果节成铃率增加。随着棉株棉铃荷重的增加,摘除所有于最早三周开的花可延缓生长、开花和结铃的下降。但是,果枝和主茎茎尖脱落酸含量并不因前期摘铃而减少,也不因棉铃荷重增加而增加。本试验结果并不支持上一假设。
The growth of cotton, flowering, slowing the end of the bell and bell desensitization. Cotton boll load effect Cotton boll loss may be via hormones. This experiment attempts to validate the hypothesis that cotton bolls produce abscisic acid and transport it to fruiting branches where it inhibits growth, blossoms and binds. Removal of flowers or young bellies from the first section of the fruiting branches did not reduce the abscisic acid content of the fruiting branches and the second fruit divisions, and had an indeterminate effect on the abscisic acid content of the second fruit section bolls. In a field trial. Removal of some bolls in the first node, the second fruit boll drop acid content decreased with the continued picking off the bell. Therefore, this effect is cumulative and not limited to a single fruit branch. The removal of flowers or bells of the first fruit branch increased the boll rate of the second fruit branch. As cotton boll weight increased, the removal of all the flowers opened in the first three weeks delayed the growth, flowering and boll reduction. However, the abscisic acid content of fruiting branches and main stem tips did not decrease due to pre-bolting and did not increase due to boll weight increase. The test results do not support the previous assumption.
