乙烯利可促使棉叶原贮藏同化物质和处理后新同化物质更多地向棉铃输送,特别是能使输向棉铃的同化物质以更多的数量在棉絮中累积,表明乙烯利是通过改变棉花光合产物的运转分配比例、提高光合产物的经济系数来促进棉花纤维充实的,但光合产物在棉籽中的分配量有所减少,因而对籽指有一定影响。棉叶的光合能力在用药后一周内变化不大,之后显著减弱。因此,过早使用乙烯利,对未长成的棉铃会因棉叶提前衰老而影响充实。乙烯利能迅速增强棉叶的呼吸强度,但六天后反而低于对照。
Ethephon allowed the original storage assimilation of cotton leaves and the newly treated assimilates to be transported more to the bolls, in particular, the assimilation of bolting to cotton bolls in more quantities, suggesting that ethephon is produced by altering cotton Photosynthetic products, the proportion of the distribution of operations to improve the economic coefficient of photosynthetic products to promote cotton fiber rich, but photosynthetic products in cotton seed distribution decreased, and thus have some impact on the index finger. The photosynthetic capacity of cotton leaves did not change much within one week after treatment, then significantly weakened. Therefore, premature use of ethephon, boll boll will not mature due to premature aging affect the fullness of cotton. Ethephon rapidly enhanced the respiration rate of cotton leaves, but was lower after 6 days than the control.
