Detached broad bean (Vicia faba L.) leaflets were water stressed; within 15 minutes, guard-cell abscisic acid (ABA) concentration increased ninefold. This result eliminates the apparent discrepancy raised by reports of no correlation between initial water-stress effects on stomata and leaf ABA concentration. Six hours after stress relief, guard-cell ABA concentration was near the prestress value, which would seem to implicate other factors in stress aftereffects on stomata.
离体蚕豆叶片受到水分胁迫;15 分钟内,保卫细胞脱落酸(ABA)浓度增加了 9 倍。这一结果消除了先前关于初始水分胁迫对气孔和叶片 ABA 浓度之间无相关性的报道所引发的明显差异。胁迫解除后 6 小时,保卫细胞 ABA 浓度接近胁迫前水平,这似乎表明其他因素也参与了胁迫对气孔的滞后效应。
