Abstract

Ten analogues of abscisic acid (ABA) have been tested for their activity in assays based on the induction of stomatal closing on isolated epidermis of Commelina communis L., and the inhibition of opening on intact leaves of Xanthium strumarium L. Three of the analogues showed activity comparable to that of ABA on the stomata of Commelina. The same analogues also showed similar activity and persistence as ABA when applied to the leaf surfaces of Xanthium. Molecular requirements for activity on stomata agree closely with those for activity in the Avena coleoptile assay. The possible value of the analogues as antitranspirants is considered.

摘要

已测试了 10 种脱落酸（ABA）类似物在基于诱导 Commelina communis L. 表皮分离的气孔关闭和抑制 Xanthium strumarium L. 完整叶片张开的测定中的活性。三种类似物在 Commelina 的气孔上显示出与 ABA 相当的活性。相同的类似物在施用于 Xanthium 的叶片表面时也表现出与 ABA 相似的活性和持久性。对气孔活性的分子要求与在燕麦胚芽鞘测定中的活性要求非常吻合。还考虑了类似物作为抗蒸腾剂的可能价值。
