| 摘 要： | Objective] The study aimed to reveal the effects of hypergravity on salt tolerance of wheat seedlings. Method] The seed germination rate (Gr) and germination index (Gi) of wheat seedlings were measured under hypergravity of 600×g or 1 000×g for 4 h and under the stress of 0.4% or 0.9% salt solution. The catalase (CAT) activity and malondialdehyde (MDA) content of wheat seedlings were also measured under 0.4% salt stress. Result] Compared with seedlings in CK group (no hypergravity or salt stress),the Gr and Gi of the seedlings in salt stress treatment decreased to different extents; while the Gr and Gi of the seedlings in treatment group (hypergravity and salt stress) increased compared with that in salt stress group. CAT in seedlings of hypergravity treatment was higher than that of CK group and 0.4% salt treatment group,meanwhile the MDA showed an opposite result. Conclusion] Hypergravity could enhance the salt resistance of wheat in specific range,and hypergravity of 600×g for 4 h performed better than that of 1 000×g for 4 h.
