Abstract
Crystalline abscisin II, with a tentative molecular formula of C(15)H(20)O(4), has been isolated from young cotton fruit. It accelerates abscission when applied in amounts as low as 0.01 microg per abscission zone. It inhibits indoleacetic acid-induced straight growth of Avena coleoptiles but has no gibberellin activity on dwarf maize.
摘要
从幼嫩棉果中分离出了结晶脱落酸II，其暂定分子式为C(15)H(20)O(4)。当以低至每个脱落区0.01微克的量施用时，它会加速脱落。它抑制吲哚乙酸诱导的燕麦胚芽鞘的直立生长，但对矮生玉米没有赤霉素活性。
