Uptake and metabolism of 1,2-[(3)H]gibberellin A(1) ([(3)H]GA(1), I) and its 3-hydroxy epimer ([(3)H]pseudoGA(1), II) by barley (Hordeum vulgare L.) half-seeds were measured after 24 hours of incubation, in the presence or absence of abscisic acid in the media. Uptake of both compounds was enhanced by abscisic acid, and abscisic acid enhanced the extent of metabolism of [(3)H]GA(1). However, [(3)H]pseudoGA(1) was not metabolized, even in the presence of abscisic acid. The significance of the stereo-chemistry of the 3-hydroxyl position is discussed.
在培养基中存在或不存在脱落酸的情况下，对大麦（Hordeum vulgare L.）半种子吸收和代谢1,2-[(3)H]赤霉素A(1)（[(3)H]GA(1)，I）及其3-羟基差向异构体（[(3)H]伪GA(1)，II）进行了24小时培养后测定。脱落酸增强了两种化合物的吸收，并且脱落酸提高了[(3)H]GA(1)的代谢程度。然而，即使在存在脱落酸的情况下，[(3)H]伪GA(1)也未被代谢。讨论了3-羟基位置立体化学的意义。
