مستخلص: | Purpose: Mixed salt stress significantly inhibits pepper germination and seedling growth, but it is unclear whether the negative effect can be mitigated by selenium (Se) addition. Methods: Four pepper varieties with large differences in salt tolerance were used as materials in this study. Based on the significant stress of mixed salts, the concentration of sodium selenite was set to 0, 5, 10, 20, 40, 80, and 120 µmol L− 1, respectively. Various parameters related to seed germination, seedling growth and development, as well as internal physiological indicators were measured, and the alleviating effects of sodium selenite on salt stress was comprehensively evaluated by fuzzy membership function method. Results: The results showed that with the increase of sodium selenite concentration, the germination rate, relative salt damage mitigation rate, root fresh weight, fresh weight above ground, root length, hypocotyl length, and seedling activity index all showed an initial increase followed by a decrease, while the contents of superoxide anion radical (O |
