Frequent extreme heat events pose a serious threat to rice production due to global warming. As a component of rice yield, increased grain weight is beneficial for further improvement of rice production. Grain weight exhibits high genetic stability; however, it often varies significantly in the same rice variety under different environmental and cultivation conditions, such as high temperature, fertilizer, and water management. Therefore, the increase and stability of grain weight are closely associated with stable rice production under extreme high temperatures. This work briefly describes the formation and regulation of rice grain weight, and reviews the underlying mechanisms of high-temperature-induced reduction in grain weight from the perspective of physiological and biochemical processes, including assimilate translocation, sugar metabolism, and hormonal changes. Additionally, cultivation management measures for mitigating high-temperature damage are summarized. Based on current research, the work also suggests possible future research directions regarding the effects of high temperature on grain weight in rice.

全球气候变暖使水稻生产持续面临极端高温威胁。粒重是水稻产量的重要构成因子,增加粒重有利于水稻产量的进一步提升。粒重具有较高的遗传稳定性,然而同一水稻品种粒重在高温、肥水管理等不同环境和栽培条件下具有较大差异。因此,粒重的增加和稳定与极端高温下水稻稳产密切相关。本文简要叙述了水稻粒重的形成及其调控,从同化物转运、糖代谢及激素变化等生理生化过程角度综述了不同时期高温导致水稻粒重降低的机理,并概述了优化栽培调控措施对高温危害的缓解作用,结合现有研究展望了未来高温影响水稻粒重的相关研究方向。

全球气候变暖使水稻生产持续面临极端高温威胁。粒重是水稻产量的重要构成因子,增加粒重有利于水稻产量的进一步提升。粒重具有较高的遗传稳定性,然而同一水稻品种粒重在高温、肥水管理等不同环境和栽培条件下具有较大差异。因此,粒重的增加和稳定与极端高温下水稻稳产密切相关。本文简要叙述了水稻粒重的形成及其调控,从同化物转运、糖代谢及激素变化等生理生化过程角度综述了不同时期高温导致水稻粒重降低的机理,并概述了优化栽培调控措施对高温危害的缓解作用,结合现有研究展望了未来高温影响水稻粒重的相关研究方向。

Frequent extreme heat events pose a serious threat to rice production due to global warming. As a component of rice yield, increased grain weight is beneficial for further improvement of rice production. Grain weight exhibits high genetic stability; however, it often varies significantly in the same rice variety under different environmental and cultivation conditions, such as high temperature, fertilizer, and water management. Therefore, the increase and stability of grain weight are closely associated with stable rice production under extreme high temperatures. This work briefly describes the formation and regulation of rice grain weight, and reviews the underlying mechanisms of high-temperature-induced reduction in grain weight from the perspective of physiological and biochemical processes, including assimilate translocation, sugar metabolism, and hormonal changes. Additionally, cultivation management measures for mitigating high-temperature damage are summarized. Based on current research, the work also suggests possible future research directions regarding the effects of high temperature on grain weight in rice.
