Germination of cottonseed (Gossypium hirsutum L.) was inhibited by abscisic acid. Inhibition was greater when seeds were soaked in abscisic acid for 5 hours and dried prior to germination than when abscisic acid was applied in the germination medium. (2-Chloroethyl)phosphonic acid, gibberellic acid, and kinetin partially overcame the inhibitory action of abscisic acid. Combinations of (2-chloroethyl)phosphonic acid with gibberellic acid or kinetin were more effective than the individual substances. Germination also was partially restored by removal of seed coats. Fusicoccin completely restored germination of abscisic acidtreated seeds.
脱落酸抑制棉籽（Gossypium hirsutum L.）的萌发。与将脱落酸应用于萌发培养基中相比，将种子浸泡在脱落酸中 5 小时并干燥后，种子的抑制作用更大。(2-氯乙基)膦酸、赤霉素和激动素部分克服了脱落酸的抑制作用。(2-氯乙基)膦酸与赤霉素或激动素的组合比单独使用这些物质更有效。去除种皮也部分恢复了萌发。赤霉素完全恢复了脱落酸处理种子的萌发。
