A crystalline substance, designated abscisin, which accelerates abscission of excised debladed petioles at 10(-2) microgram per abscission zone, has been isolated from cotton burs. The yield was approximately 1 milligram from 10 kilograms of dry plant material.
一种结晶物质，命名为脱落素，在 10（-2）微克/脱落区的浓度下可以加速离体去叶叶柄的脱落，已从棉铃中分离得到。从 10 公斤干植物材料中，大约可以得到 1 毫克的脱落素。
