In different months of the growing season, fruit inclusions (tannin, anthocyanins), pH, buffer capacity of different disease re- sistance were determined and analyzed, and the results were as follows. In the seasonal occurrence of anthracnose, the relations between the incidence rate and plant physiological and biochemical characteristics indicated that the fruit tannins content in
