摘　　要： Based on growth level and peroxidase activity,a comparative study and paried-samples t test were made between virus-free Zaosu pear seedlings and the seedlings inoculated with apple stem grooving virus(ASGV). The results showed : (1) virus-free Zaosu pear seedlings grew better than inoculated ones. Of the seedlings the height,diameter,branches and autumn braches differed statistically significantly; (2)the peroxidase activity of inoculated seedlings was higher than that of virus-free ones,and the peak of peroxidase activity occurred on about d 7 and d 24 after inoculation.
