Abstract
Using as test material the Phoebe zhennan seeds of different vigor,which were obtained by aging the seeds with different aging time,the paper measured and evaluated their contents of O2-· and H2O2,and the activities of SOD,CAT and POD.Results show that the contents of O2-·.and H2O2 increase quickly after the seeds are aged and the activities of SOD,CAT and POD decrease greatly after aging for 36 h,leading to the breaking of the balance between free radicals' producing and scavenging and to the decreasing of the ability of O2-· and H2O2 scavenging;and that the cells of the seeds are damaged,thus their vigor decreasing.
