Abstract
Coleoptile growth of intact rice seedlings under submerged conditions was not much affected by the continuous irradiation of red light. But, if aerated, growth was strongly inhibited by a low-energy brief irradiation of red light, and this red light-induced effect was reversed by a brief exposure to far-red light. The responses to red and far-red light were repeatedly reversible. The amount of photometrically detectable phytochrome in non-aerated coleoptile tissues was found to be as low as one third that in aerated ones. After the conversion of Pr to Pfr by a brief red irradiation, the total Δ (ΔA) of the aerated tissues decreased to about one fifth that of the original level within 6 hr at 24°C, while the Pfr in the non-aerated tissues was significantly less decayed.
