Abstract: Two weeks after inoculation with ToMV, the activities of POD, PPO and PAL, and changes in peroxidase isozyme patterns in six varieties of tomato with different levels of resistance were analyzed. The result show that the levels of POD, PPO and PAL activity in inoculated plants were higher than that in noninoculated ones, that the more susceptible the variety, the more its changes in inoculated plants. There were two new isozyme bands appeared in susceptible variety, and only one new isozyme band appeared in resistant variety.
