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.
