Abstract

Soil salinization is one of the main abiotic stress factors impacting the growth of crops and the agricultural industry today. Thus, we aimed to investigate the effects of H 2 O 2 pretreatment on seed germination in Tartary buckwheat ( Fagopyrum tataricum ) seeds under salt stress and to evaluate this species' salt tolerance. Through the preliminary experiment, this study used 50 mmol L -1 NaCl solution to induce seed stress. After soaking for 12 h in different H 2 O 2 concentrations, seeds were laid in Petri dishes with 50 mmol L -1 NaCl for seven days and the germination parameters and physiological indicators were measured to screen the optimal H 2 O 2 pretreatment concentration and the salt tolerance index. Our results indicated that pretreatment with 5-10 mmol L -1 H 2 O 2 was most effective in alleviating NaCl's impacts on the seeds' germination parameters. Furthermore, the growth and material accumulation of seedlings was promoted; catalase, superoxide dismutase activity, and proline content were enhanced; and malondialdehyde content was reduced. Principal component analysis and stepwise regression revealed six key indicators that had a significant impact on the salt tolerance characteristics of F. tataricum , namely, germination potential, shoot fresh weight, root surface area, root average diameter, catalase activity, and superoxide dismutase activity.
