对黄化植物暴露于光下生长迟缓的一种解释是，光诱导形成一种生长抑制物，据报道，光照后植物体内抑制物的浓度增加。在这两篇报道中，3,4抑制剂具有与脱落酸（ABA）相似的色谱性质。根据这一证据和其他证据，人们推测ABA前体可能在黑暗中形成，并在光照下转化为ABA。
ONE explanation of the retardation of growth1when etiolated plants are exposed to light is that light induces the formation of a growth inhibitor2, and increased concentrations of inhibitors in plants after illumination have been reported3–6. In two of these reports3,4the inhibitor had chromatographic properties similar to those of abscisic acid (ABA). From this and other evidence it was postulated that an ABA precursor might be formed in darkness and converted to ABA in the light7.
