The tolerance of Sphagneticola trilobata and its hybrid to cadmium stress

Year: 2026

Type: article

Abstract: During the invasion process, Sphagneticola trilobata produced a hybrid with native species. In this study, the adaptability of S. trilobata and its hybrid was investigated under cadmium (Cd) stress. Results showed that the net photosynthetic rate and maximum quantum yield of PSII photochemistry of S. trilobata leaves were significantly lower than those in the hybrid, while malondialdehyde and electrolyte leakage were significantly higher than those in the hybrid. The accumulation of Cd in the hybrid was significantly higher than that in S. trilobata, and more active detoxification strategies were shown in the hybrid. The antioxidant enzyme activity in the hybrid was significantly higher than that in S. trilobata. Compared with S. trilobata, more Cd was accumulated in the cell walls and transformed into less toxic chemical forms in the hybrid. The results indicate that hybridization of S. trilobata with native species during invasion enhances the adaptability of the hybrid to Cd stress.
