| Abstract: | Polygonati rhizoma is used as traditional Chinese medicine and nutritional food. Polygonatum kingianum is one of the three source species of polygonati rhizoma. Rhizome rot disease is a serious constraint to the production of P. kingianum in Yunnan Province. Two kinds of purified fungal isolates, named PkF01 and PkF02, were obtained from the rhizome rot samples. Based on morphology, analysis of tef1α and rpb2 gene sequences, two fungal strains PkF01 and PkF02 were designated as Fusarium oxysporum and F. solani, respectively. According to pathogenetic tests fufilling Koch's postulates, F. oxysporum and F. solani were identified as causal agents of rhizome rot of P. kingianum. The former showed a stronger pathogenicity on the rhizomes of P. kingianum than that of the latter one. This result is helpful to control rhizome rot on P. kingianum. |
