Abstract The objective of this study was to explain the physiological mechanisms through which NaSeO mitigates the growth and developmental inhibition of pakchoi under HgCl stress. The results showed that treatment with HgCl (40 mg L) led to reduced biomass, dwarfing, root shortening, and root tip necrosis in pakchoi. Compared to control (CK), the activities of superoxide dismutase (SOD) and peroxidase (POD) in Hg treatment increased, and the content of malondialdehyde (MDA) also dramatically increased, which negatively impacted the growth of pakchoi. Low concentrations of NaSeO (0.2 mg L) significantly increased the content of soluble sugars… More >
