高温对水稻粒重形成的影响及其栽培调控研究进展
Research Progress on Effects of High Temperature on Rice Grain Weight Formation and Cultivation Strategies
摘要
Abstract
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.关键词
