Abstract:
Using the seeds of ‘Qiangli 50’ cabbage as material，the seed germination characteristics，changes in relative electric conductivity，content of MDA，content of soluble sugar and soluble protein during three different artificial aging methods (hot and humid aging method，methanol solution aging method，hot water aging method) were investigated.The results showed that the germination rate，germination potential，germination index and vigor index of cabbage seeds were significantly reduced by three aging methods and the average germination days were significantly prolonged，and the degree of influence increased with the prolongation of treatment time.Among them，methanol solution aging method and hot water aging method had greater effects on germination characteristics of cabbage seeds.The relative conductivity of the leaching solution of cabbage seeds was significantly increased by three aging methods，and the contents of soluble sugar，soluble protein and MDA of cabbage seeds were significantly reduced.The results of correlation analysis between seed germination characteristics and physiological indicators showed that there were significant correlations between seed germination characteristics and relative conductivity，soluble protein content，soluble sugar content and malondialdehyde content，and we analyzed the reasons for the decline of vigor of cabbage seeds caused by different artificial aging methods.This study provided a technical reference for adopting the most suitable conditions in the artificial aging of cabbage seeds.
