稻米品质形成和调控机理概述

Review on Rice Quality Formation and its Regulation Mechanism

针对国内外稻米品质的研究现状,分析了稻米品质的形成机制,探讨了不同生育期稻米品质形成的影响因素。在全球气候变化的背景之下,如何适应CO2浓度和温度增高的影响将是今后提高稻米品质的研究方向之一。

This paper introduced the evaluation criteria of rice quality, for rice appearance quality, milling quality, cooking quality, eating quality and nutrition quality, according to the research of rice quality in China and abroad. Moreover, the mechanism of the rice quality formation was discussed, which mainly included the relationship between the organization structure, the material basis and the rice quality, as well as the influence factors in different growth stages of the formation of the rice quality. Furthermore, in this paper, the influencing factors of the rice quality was analyzed from genetic characteristics and environmental factors. In conclusion, starch and protein play an important role in rice quality formation. And the change of environmental factors would affect the synthesis and accumulation of starch. The environmental factors covered temperature, light, CO2 and others. In the background of global climate change, we should take appropriate measures to adjust to the influence of the increasing of the temperature and the CO2 density, so as to improve rice quality. It should be regarded as one of the research direction about improving rice quality in future.
