摘要
保障水稻产量是应对全球人口增长以及粮食危机的关键举措之一.水稻穗分化期遭遇高温天气的概率日益增加,并对该区域内水稻的安全生产造成了极大威胁,因此开展相关研究意义重大.文章从幼穗形成、花药结构和花粉发育、产量与品质以及对水稻生理指标、代谢调控机理的影响等方面综述了穗分化期高温对水稻的影响并提出相应的缓解措施,并对研究前景作出展望,以期为开展水稻逆境生理研究以及缓解措施的合理选择提供依据.
Abstract
Ensuring rice yield is one of the key measures to cope with the global population growth and food crisis.The probability of high temperature weather in the panicle differentiation stage of rice is increasing,which poses a great threat to the safety of rice production in this region,so it is of great significance to carry out relevant research.In this paper,the effects of high temperature on young panicle formation,anther structure,pollen development,yield and quality,physiological indexes and metabolic regulation mechanism of rice during panicle differentiation were re-viewed,and corresponding mitigation measures were put forward,in order to provide a basis for the study of rice stress physiology and the reasonable selection of mitigation measures.
