The effect of abscisic acid on cotton (Gossypium hirsutum L. cv. Acala 4-42) and bean (Phaseolus vulgaris L. cv. Red Kidney) explants was 2-fold. It increased ethylene production from the explants, which was found to account for some of its ability to accelerate abscission. Absci is acid also increased the activity of cellulase. Increased synthesis of cellulase was not du to an increase in aging of the explants but rather was an effect of abscisic acid on the processes that lead to cellulase synthesis or activity.
脱落酸对棉花（陆地棉品种阿卡拉4-42）和菜豆（菜豆品种红腰豆）外植体有双重作用。它增加了外植体乙烯的生成量，而乙烯生成量的增加被认为是脱落酸加速脱落能力的部分原因。脱落酸还提高了纤维素酶的活性。纤维素酶合成量的增加并非由于外植体衰老加剧，而是脱落酸对导致纤维素酶合成或活性的过程产生的影响。
