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.

Lag Period

The opening movements of both V. faha stomata and A. julibris8in pinnules have been shown previously to depend on a redistribution of potassium ions under the influence of light. Action spectra for both systems show peak effectiveness in blue light, at 440 nm, but for pinnule opening in A. julibri88in there is a subsidiary peak in the far red (720 nm). However, opening in far red shows an initial lag period, whereas opening in blue light is rapid. The action spectrum for pinnule opening was not influenced by leaf age, the presence or absence of CO2, or by simultaneous red light.
