离体蚕豆（Vicia faba L.）小叶受到水分胁迫； 15 分钟内，保卫细胞脱落酸 (ABA) 浓度增加了九倍。 这一结果消除了最初水分胁迫对气孔的影响与叶片 ABA 浓度之间不存在相关性的报道所引起的明显差异。 应激缓解后 6 小时，保卫细胞 ABA 浓度接近应激前值，这似乎暗示了气孔应激后效应中的其他因素。
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.
