水稻粒重生理特性及遗传分析研究进展

Research Progress of Physiological Characteristics and Genetic Analysis on Rice Kernel Weight

粒重是水稻产量构成的主要因素之一。粒重的增加对水稻产量的增加有着积极的作用。该研究揭示影响水稻粒重的生理变化和遗传规律,可对粮食产量的提高有着重大的意义。综述了灌浆生理特性与粒重的关系、影响水稻粒重的生理生化特性、激素对粒重的影响以及粒重的遗传特点,并且对粒重育种的应用进行了展望。

Grain weight is one of the main factors of rice yield components, increasing of grain weight has a positive effect on rice production. Revealing the effects of physical changes and genetic law on grain weight of rice, is of great significance in raising the output of grain. Effects of grouting physiological characteristics, physiological and biochemical characteristics, hormone on grain weight of rice were reviewed, as well as genetic characteristics of grain weight. The application of grain weight breeding was forecasted.
