Abstract:
Taking Artemisia annua seeds and seedlings as the experimental materials,different concentrations of salicylic acid (SA) and gibberellin (GA3) were used to soak Artemisia annua seeds under salt stress.The changes in germination indicators,seedling growth,and physiological and biochemical indicators of Artemisia annua seeds after soaking were studied,in order to provide reference for improving its salt tolerance and alleviating the damage of salt stress to Artemisia annua.The results showed that with 150 mmol·L-1 NaCl treatments，seed germination and seedling growth of A.annua were all strongly inhibited.Under salt stress，A.annua′s seed germination index，seedling growth index，and physiological and biochemical index increased originally and then dropped as SA and GA3 concentrations increased.With 0.3 mmol·L-1 SA and 400 μmol·L-1 GA3 soaking greatly alleviated the adverse effects of salt stress on A.annua seed.In conclusion，exogenous SA and GA3 soaking treatment with appropriate concentration could significantly increase the germination rate of A.annua seeds，improve the salt tolerance of seeds，and mitigate the inhibition of salt on seedling growth.
