Abstract:

Six morphologically different Colletotrichum strains were obtained during the investigation of Liquidambar formosana Hance leaf diseases in Fujian. The six strains were identified based on morphology (colony, acervuli, conidiophores and conidia) and multi-loci (ITS, TUB2, ACT, GAPDH and CHS-1) phylogenetic analyses. The six strains belonged to three Colletotrichum species, i.e., C. fructicola, C. tropicale and C. fioriniae, which belonged to Colletotrichum gloeosporioides complex and Colletotrichum actatum complex, respectively. The results from Koch’s postulates supported the three Colletotrichum species could cause leaf anthracnose to Liquidambar formosana, and the pathogenecity of them was different. This is the first report of the three Colletotrichum species to cause leaf anthracnose on Liquidambar formosana.

Key words: anthracnose, Liquidambar formosana, identification, phylogenetic analyses
