Abstract:
Taking ‘Wanfeng’ cabbage seeds as material，PEG penetrant combination treatment with different molecular weight，concentration，treatment time were adopted to natural aging and artificial aging of seeds，the effects of different combination of PEG treatment on soluble protein content，malondialdehyde (MDA) content，superoxide dismutase (SOD)，catalase (CAT) and peroxidase (POD) activity were compared.The results showed that PEG had some repair effect on aging seed，could improve seed vigor.PEG molecular had significant influence on natural aging seeds，followed by was the factors of PEG concentration，the minimum was PEG treatment time.Aging seed metabolic germination had changed after PEG-osmotic processes，including MDA content was lower than control，soluble protein content increased，antioxidant enzymes activity was higher than CK.At the same time due to aging conditions，there were difference on physiological and biochemical between the natural aging and artificial aging seeds，including the PEG induced reactions，natural aging seeds had the most obvious induced reactions after PEG triggered.
