The present test is intented to explora the changes in activities of PO and SOD and cormposition of isozyme bands within a week after the corns with different resistance being incoculated with MDMV. The original result indicates that the activities of PO and SOD change obviously and that the test groups have increased more activities than the contrast groups. There are some differences in PO hands between the Anti-MDMV strains and the infective ones, and it is the same as between the test groups and the contrast ones. The anti-MDMV bands have more stripes and deeper color in there figureprints, while the infective bands hav eless stripes and lighter color or no color. The basic level of SOD activities of anti-MDMV strains is higher than that of the infective ones. After being infected, the SOD activity rises higher in the test groups than in the health contrast groups, but it isn^t distince, while the SOD activity of the infective strains rises obviously, and its does so gradually.
