Abstract
A brief irradiation of red light increased peroxidase activity in leaves which was reversed by far-red light of short duration. The onset and magnitude of the photoresponse was age dependent. In 6-day-old leaves, photoreversibility by red and far-red light was shown, whereas in 3-day-old leaves no response was noted. Peroxidase in leaves was a soluble enzyme and phytochrome mediated increase in activity was mainly confined to the supernatant.
