| To explore the effect of different degrees of drought stress on soybean agronomic traits, photosynthetic physiology, yield and quality, soybean varieties Longzhonghuang 601, Longzhonghuang 602, Zhongpin 661 and Jindou 21 were used as materials in drought\|resistant sheds from 2020 to 2021, and three levels of normal irrigation (CK), moderate drought (D1), and severe drought (D222Pn at flowering stage decreased the most, which was 45.15% lower than that of CK, and SPAD value at seedling stage increased the greatest with 21.92%. The content of the main indicators related to quality showed an upward trend with the increase of drought degree. Under D2 |
