Effect of fluoride on in vivo nitrate reduction in the rive leaves (Oryza sativa L.).
Fluoride had no effect on in vitro nitrate reductase activity in rice leaves, but in vivo activity was strongly inhibited. It is suggested that fluoride brings about this inhibition by adversely affecting the physiological NADH generating system required for in vivo nitrate reduction.
