Abstract

Extreme climatic exposure due to global warming and climate change has direct or indirect consequences on rice yield and quality. The burgeoning population and socioeconomic progress are stimulating the growing demand for good-quality rice worldwide. Climate change research on rice always emphasizes yield, while more could be learned about quality. Thorough research about extreme high and low temperatures effects on rice at crucial growth stages remains mostly unknown and results in limited attempts to explicate the underlying concept. Climatic factors often pose a threat to the vegetative and reproductive development of rice and might play a vital role in grain quality change but a lack of thorough research has been done yet. Rice is one of the major agricultural commodities that provide more calorie and nutritional benefits compared to other cereals. Frequent climate change causes certain alterations in rice quality, while temperature and light intensity are the major challenges. Thus, it is important to quantify how rice grain quality will respond to climate change in the future. Rapid economic development coinciding with serious pollution results in severe solar dimming and discrete temperature increases in divergent rice-cultivating countries. Fluctuation in rice ecology – temperature, solar radiation, CO2 and O3 – has a domino effect to hamper grain quality traits. Responses of rice grain quality traits – appearance, cooking, flavor, and nutrition – to extreme climatic factors enable us to clarify the insights of changes. If we are to escape the destructive impacts of extreme temperatures, need to identify the most sensitive periods, patterns of yield losses and underlying mechanisms of mutable rice quality. We used books, previous field or phytotron research and review articles to create a comprehensive sole literature. We find that the extreme temperature influence on rice coinciding with impending global warming simulation is methodically understated. The demonstration of evidence allows case studies corresponding with typical spatiotemporal temperature in neoteric and intensive forms of analysis on rice yield and quality, combined with morpho-physiology and molecular research. This review will be associated with the enhancement of agricultural sustainability in future climate change.
