Study on the Response Mechanism of Wheat Physiological Characteristics, Yield and Quality under Drought Stress

Abstract

This paper takes wheat as the research object, and systematically studies the effects of drought stress on wheat physiological characteristics, yield and quality. By analyzing some physiological indicators, yield and quality of wheat Xinnong 106 variety under drought stress during the grain filling period, the influence mechanism of drought stress on wheat growth, development and output was explored. The results showed that drought stress has a significant effect on wheat physiological traits, root growth, grain filling characteristics and quality formation. On this basis, a regulatory strategy to alleviate the effects of drought stress on wheat yield and quality is proposed, which provides a theoretical basis for my country's wheat industry to cope with drought disasters.
