| 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. |
