[Interactive effects of temperature, CO₂ concentration and precipitation on growth and yield of crops]

Temperature, CO₂ concentration and precipitation are the key climate factors affecting crop growth and yield. The effects of different climate factors on crops are not independent, and their interactive effects on crops have become a focus in this research field. The study of interactive effects of multiple climate factors on crops could more reliably reflect the actual situations of crop growth, which could help us to understand the crop growth and even the ecosystem response to climate change, and optimize agricultural production managements in the future. In recent years, there are a lot of reports about the effects of different climate factors on crops both in China and abroad, and thus it is quite difficult to conduct a comprehensive review for interactive effects of all climatic factors on crops. Therefore, this review only focused on the results of the interactive effects of warming, elevated CO₂ concentration and changing precipitation on crop growth, photosynthetic physio-logy, and yield in recent years, and identified the knowledge gaps of the relevant studies and the key issues that urgently need to be solved in future research. This would be useful for the researches elucidating the influence of climate change on crop growth and yield.
