摘要/Abstract

摘要： 玉米灌浆速率影响干物质的积累和后期的子粒脱水过程,要获得高产优质的玉米必须深入了解玉米子粒灌浆特性。玉米子粒灌浆过程受遗传和环境两个方面共同影响,是一个动态变化的复杂生理代谢过程。对玉米子粒灌浆的生理特性以及子粒灌浆速率的分子调控机制进行概述,为通过调控玉米子粒灌浆速率实现玉米增产提质提供理论依据。

Abstract: Maize grain filling rate affects the accumulation of dry substances and the grain dehydration process after physical mature. To obtain high yield and high quality corn, the characteristics of corn grain grouting must be elucidated deeply. Maize grain filling process is a complex dynamic physiological metabolic process, which is jointly affected by both genetic effects and environmental factors. Here, the physiological characteristics of the maize grain filling process and the molecular mechanism of maize grain filling rate were summarized, and this review will provide informative theoretical genetic basis for the high-yield maize breeding in the future.
