Research Advances in High Temperature Stress on the Grain-filling and Quality of Rice and Its Mechanism
High temperature stress is the main environmental factor that threatens grain yield and quality of rice.This paper summarized the effects of high temperature stress on grain-filling and rice quality formation,and reviewed its biological mechanism from the aspects of assimilates accumulation and transport,activities of key enzyme involved carbon and nitrogen metabolism,endogenous hormones and molecular mechanism,and discussed the key technical measures to alleviate the high temperature damage on rice and considerable suggestions for future study.The review may provide insights for guiding cultivation and breeding of thermo-tolerance rice.
