Photosynthetic traits, water use and the yield of maize are influenced by soil water stability
In conclusion, SW exhibits a positive effect on maize leaf water content, photosynthetic carbon assimilation, and grain yields, regardless of soil water content. Compared to FW, SW increased leaf WUE and maize yield by enhancing photosynthesis, and SW has stronger discrimination against <sup>13</sup>C during photosynthetic CO<sub>2</sub> assimilation, thus decreasing leaf δ<sup>13</sup>C. This study fills a gap in understanding how soil water stability influences maize yield and gas exchange, and provides a fresh perspective on how to improve crop yield and WUE by managing soil water stability.
