Abstract

Abstract: The pathogen of Passiflora coerulea L. stem rot in Baise City, Guangxi were isolated, cultured and identified by means of tissue separation, Koch's rule and rDNA-ITS sequencing. The results showed that 6 kinds of pathogenic fungi with different morphology and pathogenicity were isolated and identified. Four strains were identified as Fusarium oxysporum, Phytophthora nicotianae, Lasiodiplodia theobromae and Fusarium moniliforme, 2 strains were identified as Fusarium, but their the species had not been identified.

Key words: Passiflora coerulea L., stem rot, Fusarium, isolation, identification

CLC Number:
