Five species of Camellia were used to study the physiological biochemistry of resistance to Colletotrionum camelliae Massee. Test results revealed that Camellia yunsiensis was most resistant, C. neitnamensis was resistant, C. semisererata was moderate resistant, C. meiocarpa was susceptible, C. oleifera was most susceptible. The values of changes in the peroxidase activity were positively correalated with disease resistance of the tested Camellia species within 48h after inoculation, while such values were positively correalated with disease susceptibility of the testad Camellia species over 48h after inoculation. The changes of the peroxidase isoenzyme bands after inoculation were evidently different than before inoculation. There were more bands of changes in the susceptible species than in the resistance ones.
