摘要 [Objectives] In this experiment, wheat seeds were treated with different concentrations of gibberellin and different concentrations of salt solution to study the change of germination index of wheat seeds. [Methods] The germination rate, germination potential and germination index of wheat seeds were measured by routine methods, and the effect of exogenous gibberellin on germination of wheat seeds under salt stress was observed. [Results] The germination rate, germination potential and germination index of wheat seeds under salt stress were significantly increased after exogenous treatment of 0.25 and 0.50 g/L gibberellin within the range of salt concentration gradient. However, when the concentration of gibberellin was too high, it would inhibit the germination of seeds. [Conclusions] Appropriate concentration of gibberellin can effectively alleviate the stress caused by salt on wheat seed germination. In this experiment, the best concentration of gibberellin to alleviate salt stress was 0.25 g/L.
