- Abstract
[Objective] To study the effects of soaking with Ce3+, VC and Ac-DEVD-CHO on the antioxidant system of Allium mongolicum Regel. seeds with different storage years. [Methods] Allium mongolicum Regel. seeds stored for 3, 5 and 7 years were soaked with distilled water (CK), CeCl3, VC, Ac-DEVD-CHO, VC+CeCl3 and Ac-DEVD-CHO+CeCl3. The activities of SOD, POD, CAT and APX, the production rate of ·O2-, and the contents of H2O2 and MDA of Allium mongolicum Regel. seeds with different treatments and storage years were measured. [Results] Compared with CK, CeCl3 treatment significantly increased the SOD activity of Allium mongolicum Regel. seeds stored for 5 and 7 years (P<0.05), different seed soaking treatments significantly increased the POD activity of Allium mongolicum Regel. seeds stored for 3 years (P<0.05), Ac-DEVD-CHO treatment significantly increased the CAT activity of Allium mongolicum Regel. seeds stored for 5 and 7 years (P<0.05), and different seed soaking treatments significantly increased the APX activity of Allium mongolicum Regel. seeds stored for 7 years (P<0.05). Compared with CK, different seed soaking treatments decreased the ·O2- production rate of Allium mongolicum Regel. seeds stored for 5 and 7 years, among which VC+CeCl3 and Ac-DEVD-CHO+CeCl3 treatments significantly decreased the ·O2- production rate of Allium mongolicum Regel. seeds (P<0.05). The treatments of VC, Ac-DEVD-CHO, VC+CeCl3 and Ac-DEVD-CHO+CeCl3 treatments significantly decreased the H2O2 content of Allium mongolicum Regel. seeds stored for 5 and 7 years (P<0.05). CeCl3 and VC treatments decreased the MDA content of Allium mongolicum Regel. seeds stored for 5 and 7 years, but no significant difference was observed (P>0.05). [Conclusion] Compared with the other seed soaking treatments, CeCl3 treatment had the best effect on improving SOD activity of Allium mongolicum Regel. seeds; generally, the combinative treatments of VC with Ac-DEVD-CHO and CeCl3 had better effect on removal of ·O2- production rate of Allium mongolicum Regel. seeds.
