Isolation and Identification of The Pathogen Fusarium Causing Maize Ear Rot in Shanxi Province
摘要
Abstract
To know the pathogens causing maize ear rot in Shanxi, the possible pathogens were isolated and purificed from the diseased samples in Jincheng and Taigu, Shanxi by the conventional tissue method. The total 53 isolates were isolated from the tissues of the maize samples collected. Based on the morphological identification, Fusarium verticil-lioides, F. graminearum and F. semitectum, respectively were identified. Among which Fusarium verticillioid.es was a predominant Fusarium species with the highest isolation rate of 46. 7% . The results of pathogenicity experiment showed that Fusarium verticillioides and F. graminearum were the pathogens of maize ear rot, and mixed infection of the two species showed a stronger pathogenicity than one species alone. The results provided a basis for further study and control practice of the disease.关键词
