Abstract
Under conditions in which the light requirement for phytochrome mediation was inferred to be above saturation, white and blue lights enhanced the extractable nitrate reductase activity of etiolated pea terminal buds above the levels engendered by red and far-red lights. The regulation of nitrate reductase by light in the terminal buds appears to involve both phytochrome and a blue-sensitive high-energy reaction.Keywords
