Abstract:
In order to investigate the effect of PEG on improving seed vigor of aged Chinese cabbage.The orthogonal test method was used to treat the aged Chinese cabbage seeds ‘Dongbai No.1’ as materials to explore the effects of different molecular weight，concentration and treatment time of the PEG on the vigor of aged Chinese cabbage seeds.Then，the contents of soluble protein，soluble sugar，MDA and the activity of antioxidant enzymes were measured，which were the factors of the aged Chinese cabbage seeds after treated with PEG.In order to obtain the degree of improving seed vigor of aged Chinese cabbage by different treatment combinations and explore the mechanism behind the improvement of seed vigor.The results showed that the PEG treatment could significantly improve seed vigor.In this experiment，the best combination of improving seed vigor was that the aged Chinese cabbage seeds induced by PEG with molecular weight of 10 000，concentration of 25% and treatment time of 8 hours.Comparing with the control，the germination potential was higher than 19.00%，the germination rate was higher than 13.67%，vigor index was 571.2 higher.The concentration had most influence，the second was molecular weight and the least was treatment time.
