Popis:	The production of ethylene by etiolated pea epicotyls (Pisum sativum L., cv. Alaska) is confined to the plumule and plumular hook portion of the epicotyl, and occurs at a rate of about 6 mul.kg(-1).hr(-1). Such a rate is sufficient to give physiologically active concentrations of ethylene within the tissue. Exposure of etiolated seedlings to a single dose of red light caused a transient decrease in ethylene production and a corresponding increase in plumular expansion. Far-red irradiation following the red light treatment decreased the red effect to the level achieved by the far-red alone, suggesting that the ethylene production mechanism is controlled by phytochrome and thus that the ethylene intervenes as a regulator in the phytochrome control of plumular expansion.
