Abstract: To investigate the relationship between seed color and storability,the artificial aged Xiangzayou 631 seeds have been used as materials to study the germination and antioxidative physiological and biochemical variation.Results showed that the germination rate of both yellow and black rape seeds decreased significantly after accelerated artificial aging,and germination of yellow seeds decreased dramatically faster than the black. Superoxide radicle production,contents of hydrogen peroxide and MDA increased by 3 d accelerated artificial aging treatment,activities of antioxidative enzyme (SOD and CAT) increased obviously,and the content of AsA declined obviously.The comparison between two color seeds showed superoxide radicle production,hydrogen peroxide contents of the yellow seeds were much higher than those of the black seeds,but the SOD activity and AsA content of yellow seeds were much lower than those of the black seeds.It can be concluded that the black seeds of Xiangzayou 631 possess stronger storability due to greater contents of  nonenzymatic antioxidants.

Key words: Xiangzayou 631, yellow and black, seeds, storability, difference
