摘要
水稻产量形成规律是水稻育种和栽培的基础理论,已成为作物学研究的热点课题。从产量构成、光合生产和源库结构方面简介了水稻产量形成规律的生理生态研究进展,分析了3个方面的研究特点和构成产量形成过程的网络关系。同时水稻产量形成是一个动态过程,水稻产量性状的最终表现决定于其生长发育过程中众多基因的表达、调控和相互作用,提出应用现代发育遗传学与分子生态学的理论和方法,深入研究水稻产量的形成规律。
A progress on physioecology for yield formation in rice is summarized, including yield components, photosyn-thetic production and source-sink characteristics. The characteristics of the three aspects and their network relation during the process of yield formation are analyzed. Meanwhile, the yield formation in rice is a dynamic process and the ultimate expression of yield traits is depended on the expression, regulation and interaction of numerous genes during the developmental process. The perspective of further research on yield formation in rice is proposed, with the application of the theory and methods of modern developmental genetics and molecular ecology.
