Seedlings of Pennisetum typhoides were grown in sodium chloride (NaCl) and gibberellic acid (GA) separately and in combination, and the effects on the activity of amylase, phosphorylase, aldolase, invertase, hexose-phosphateisomerase, sucrose-synthetase and sucrose-6-phosphate-synthetase were studied. Treatment of the seedlings with NaCl caused an inhibition of the activity of amylase and invertase in the leaf homogenate, but enhanced that of phosphorylase, aldolase, sucrose-synthetase and sucrose-6-phosphate-synthetase. GA alone, as observed earlier, promoted the activity of invertase but indicated no significant influence on the other enzymes tested. In combination with salt, however, GA tended to counteract, partially or wholly, the effect of NaCl on the activity of several enzymes tested. The possible significance of the similarities between the action of abscisic acid (ABA) and salinity in influencing growth and metabolism of plants during stress is discussed.
将狼尾草幼苗分别置于氯化钠（NaCl）和赤霉素（GA）中培养，以及二者组合培养，研究其对淀粉酶、磷酸化酶、醛缩酶、转化酶、己糖磷酸异构酶、蔗糖合成酶和蔗糖 - 6 - 磷酸合成酶活性的影响。用NaCl处理幼苗会抑制叶片匀浆中淀粉酶和转化酶的活性，但会增强磷酸化酶、醛缩酶、蔗糖合成酶和蔗糖 - 6 - 磷酸合成酶的活性。如先前观察到的，单独使用GA会促进转化酶的活性，但对所测试的其他酶没有显著影响。然而，与盐共同作用时，GA倾向于部分或完全抵消NaCl对几种所测试酶活性的影响。文中讨论了脱落酸（ABA）和盐度在胁迫期间影响植物生长和代谢的作用之间相似性的可能意义。
