Global dimming reduces incident radiation, and thus affects rice yield. Canopy structure is closely related to light interception, internal light distribution, photosynthesis and radiation use efficiency (RUE). However, less attention is paid to the effects of global dimming on rice canopy structure. Whether weak light leads to poor canopy structure and thus affects light distribution and RUE, thereby reducing dry matter accumulation and grain yield remains unknown.

全局变暗下水稻冠层结构的变化


全局变暗减少了入射辐射，从而影响了水稻产量。冠层结构与光拦截、内部光分布、光合作用和辐射利用效率 （RUE） 密切相关。然而，人们对全局调光对水稻冠层结构的影响关注较少。弱光是否导致冠层结构不良，从而影响光分布和 RUE，从而减少干物质积累和籽粒产量仍是未知数。
