Effect of Water Stress on the Growth and Yield of Winter Wheat
The growth and yield of winter wheat under different water stress levels were analysed. Results showed that water stress at seeding stage was not beneficial for the growth of leaf area. Water stress slowed down the growth of height and leaf area at jointing stage. Moreover, a significant decrease in the leaf area index occurred during the heading and filling stage. The water consumptions in jointing-heading and heading-filling stages were larger. The yield of winter wheat decreased under water stress in each stage of growth, and mild water stress improved the water use efficiency of winter wheat. Appropriate water stress could improve the yield and decrease the water consumption.
