Abstract
Nitrate reductase (NR) activity in the leaves of Cocos nucifera L. exhibited a strong diurnal rhythm with a peak at 2 p.m. This rhythm was maintained under permanent dark or light conditions indicating the endogenous control of the rhythm. The NR activity was independent of tissue nitrate level. The study suggested a possible regulatory role of sugars on leaf NR activity.
