Abstract: To study the physiological response discrepancy of pericarp of litchi after inoculated by Colletotrichum gloeosporioides with different pathogenicity, the strong pathogenicity strain 0977-19-2 and the weak strain 09619-1-1, were used to inoculate on pericarps of litchi in vitro. And the control was not inoculation. The results showed that the quantities of total phenols and anthocyanin were reduced in all treats. But the range of reducing in treat inoculated by strong strain was the biggest, and the quantity was the lowest at a same moment. The activity of CAT,APX,GR increased with time except SOD. The rangeability of activity was bigger in treat inoculated with strong strain than other treats. The amount of MDA and the activities of PG, CHT, cellulose, β-1,3-glucanase were increased in all treats, but the range of increased was the bigger in treat inoculated by strong strain than the other treats.
