Major research on photosynthesis has been carried out under steady light. However, in the natural environment, steady light is rare, and light intensity is always changing. Changing light affects (usually reduces) photosynthetic carbon assimilation and causes decreases in biomass and yield. Ecologists first observed the importance of changing light for plant growth in the understory; other researchers noticed that changing light in the crop canopy also seriously affects yield. Here, we review the effects of environmental and non-environmental factors on dynamic photosynthetic carbon assimilation under changing light in higher plants. In general, dynamic photosynthesis is more sensitive to environmental and non-environmental factors than steady photosynthesis, and dynamic photosynthesis is more diverse than steady photosynthesis. Finally, we discuss the challenges of photosynthetic research under changing light.
关于光合作用的主要研究是在稳定光照条件下进行的。然而，在自然环境中，稳定光照很少见，光照强度总是在变化。变化的光照会影响（通常是降低）光合碳同化，并导致生物量和产量下降。生态学家首先观察到林下变化光照对植物生长的重要性；其他研究人员注意到作物冠层中的变化光照也会严重影响产量。在这里，我们综述了环境和非环境因素对高等植物在变化光照下动态光合碳同化的影响。一般来说，动态光合作用比稳定光合作用对环境和非环境因素更敏感，并且动态光合作用比稳定光合作用更多样化。最后，我们讨论了变化光照下光合研究面临的挑战。
