Abstract
Phaseic acid was tentatively identified in cotton fruit; this is the second report of its natural occurrence. It was found in cotton fruit of all ages, from very young to fully mature fruit. It accelerates abscission in the excised nodes of cotton seedlings, but has only about one-tenth of the abscission-promoting activity of abscisic acid.
摘要
棉铃中曾暂定鉴定出赤霉素酸；这是其天然存在的第二次报告。在各个年龄段的棉铃中均发现了赤霉素酸，从非常年轻的果实到完全成熟的果实。它能加速棉苗离体节间的脱落，但只有脱落酸促进脱落活性的约十分之一。
