Abstract

Changes in NADH- and NADPH-linked glutamic dehydrogenase (GDH) activity have been measured following illumination of etiolated barley leaves. Both activities initially increase, then decrease to below the etiolated value. The latter change is dependent upon prior illumination but independent of the presence of roots or added ammonium sulphate. Subsequently a sustained increase of both activities occurs. Possible reasons for these changes and alterations in the ratio of the two GDH activities are discussed.

摘要

已测量了暗培养的大麦叶片照光后 NADH 和 NADPH 连接的谷氨酸脱氢酶（GDH）活性的变化。两种活性最初增加，然后下降到低于暗培养的值。后一种变化依赖于先前的照光，但与根的存在或添加的硫酸铵无关。随后两种活性都持续增加。讨论了这些变化的可能原因以及两种 GDH 活性比值的改变。
