Abstract:

Early rice often suffers from low temperature during rice seedling raising, which seriously affects the quality of rice seedlings, and the growth and development of rice in paddy field, and reduces rice yield. It is of great significance to study the effect of low temperature on rice growth and development and the appropriate exogenous regulation pathways to ensure the production of early rice in China. In this work, the effects of low temperature on early rice seedlings, vegetative growth and reproductive growth were reviewed, and the physiological, biochemical and molecular mechanisms of rice responding to low temperature stress were summarized, including antioxidant system and the expression of low temperature induced genes. Finally, we put forward the measurements to improve the tolerance of rice to low temperature stress, such as screening of rice varieties with low temperature tolerance, application of exogenous hormones and reasonable fertilization. The research prospects of improving the tolerance of rice to low temperature and expanding the area of early rice in China were also put forward, such as screening of excellent rice varieties with low temperature tolerance and integrated agronomic cultivation technology.

Key words: early rice, low temperature, seedling raising, gene, growth and development, regulation

摘要:

早稻育秧期间低温频发,严重影响水稻秧苗质量,抑制水稻在大田期间的生长发育,导致水稻减产。深入研究低温对水稻生长发育的影响及适宜的外源调控途径对保障我国早稻生产具有重要意义。本文综述了低温对早稻秧苗期、营养生长期与生殖生长期的影响,概括了水稻响应低温胁迫的生理、生化和分子机制,包括抗氧化系统、低温应答基因表达等。最终提出了运用耐低温水稻品种筛选、外源激素施加和合理施肥等提高水稻耐低温胁迫的措施,并指出未来应加强筛选优良抗寒水稻品种和集成农艺栽培配套技术等措施提高水稻低温耐性和扩大我国早稻面积。
