Leaf morphology and chlorophyll fluorescence characteristics of mulberry seedlings under waterlogging stress

Abstract Because of its high flooding tolerance, in recent years, mulberry has become a tree species that is used in plant restoration in impact zones in reservoir areas. Therefore, 3-year-old potted forage mulberry seedlings were used to investigate the mechanism of mulberry adaptation to flooding...
