Quantification of different species of Colletotrichum on tea plant cultivar LJ43. a Photos of anthracnose leaf symptoms developed 6 days post inoculation (6 DPI). SX_6: C. fructicola SX_6; E-8-1: C. siamense E-8-1; ZJ1A2: C. fioriniae ZJ1A2. b qRT-PCR-based biomass of Colletotrichum spp. growth on tea plants (6 DPI). The ratio of the primer pairs ITS/Cs18SrDNA1 was used to determine the fungal biomass. The letters a and b represent significant differences between the quantification of different species of Colletotrichum according to LSD test (P < 0.05)
