In blue light (350-500 nm) the rate of photosynthesis (oxygen evolution) of Acetabularia is almost constant after a short period of transition (Fig. 1). In red light (600-700 nm), however, it decreases within 2-3 weeks almost to zero (compensation point). The photosynthetic apparatus is not damaged irreversibly by red light, because transfering the cell from continuous red light (2 weeks) to continous blue light results in an increase of the rate of photosynthesis within 3 days up to the level in blue light (Fig. 5). Photosynthesis can also be stimulated if continuous red light is interrupted daily by short breaks of blue light. The rate of photosynthesis at the end of the induction period depends upon the amount of blue light per day (Fig. 5 and 6) and is probably proportional to the logarithm of this amount.Cell growth (Figs. 2, 7, 8) and formation of dry matter (Figs. 3, 9) in continuous red light, in blue light and in continuous red light supplemented by blue light is controlled by the rate of photosynthesis under these light condition.
在蓝光（350 - 500纳米）下，经过短时间的过渡后，伞藻的光合作用速率（氧气释放）几乎保持恒定（图1）。然而，在红光（600 - 700纳米）下，其光合作用速率在2 - 3周内几乎降至零（补偿点）。光合装置并未因红光而受到不可逆转的损害，因为将细胞从持续红光（2周）转移到持续蓝光下，3天内光合作用速率会增加至蓝光下的水平（图5）。如果每天用短时间的蓝光中断持续的红光，光合作用也会受到刺激。诱导期结束时的光合作用速率取决于每天蓝光的量（图5和图6），并且可能与该量的对数成正比。在持续红光、蓝光以及补充蓝光的持续红光条件下，细胞生长（图2、7、8）和干物质形成（图3、9）受这些光照条件下的光合作用速率控制。
