摘要：

Phytochrome controlled chloroplast movement in Mougeotia is induced by flashes of polarized red light. Two subsequent flashes, separated by a dark interval of a few seconds, are much more effective than 2 simultaneous flashes; a maximal cumulative effect is reached if the duration of the dark interval is 30 ms or longer. Two light reactions in series are proposed, separated by a very fast dark reaction. Preliminary evidence is given that the energy requirement for these light reactions is different. The 2 reactions may be related in some way to free and bound phytochrome.
