Light deficiency and waterlogging affect chlorophyll metabolism and photosynthesis in Magnolia sinostellata

Key message In Magnolia sinostellata plants grown under shading and waterlogging conditions, solar noon PFD level of 1050 ± 30 µmol·m− 2·s− 1 and running water combined treatment (L1W2) triggers changes in chlorophyll metabolism and photosynthesis, which benefits growth of this endangered species.
