Abstract:

It is of great significance to study grain yield and quality characteristics for breeding and cultivation of rice with high quality and high yield. Polyamines (PAs) and ethylene (ETH) are two important endogenous plant growth regulators, which play crucial roles in regulating grain filling, grain weight and quality in rice. In this manuscript, we introduced the characteristics of PAs, ETH, grain filling, grain weight and rice quality, briefly described the relationships of grain filling with grain weight and quality, and then focused on reviewing the regulation and physiological mechanism of PAs and ETH on grain filling, grain weight, and quality (including milling, appearance and nutritional qualities, and grain starch quality) in rice. The existing problems and future research direction were also discussed.

Key words: rice, free polyamines, ethylene evolution rate, grain filling, grain weight, quality

摘要:

研究水稻产量与品质特性对水稻优质高产育种和栽培具有重要意义。多胺与乙烯作为两类重要的内源植物生长调节物质,对水稻籽粒灌浆充实、粒重和品质形成具有重要的调控作用。本文分别介绍了水稻籽粒多胺与乙烯、灌浆充实、粒重和品质特性,简述了灌浆与粒重和品质形成的关系,重点综述了水稻灌浆期籽粒多胺与乙烯对灌浆充实、粒重和品质(稻米加工、外观和营养品质及籽粒淀粉品质)的调控作用及其生理机制,讨论了存在的问题和今后的研究方向。
