槟榔烂果病的病原菌鉴定

Rotten Fruit Disease Pathogen Identification that Isolated from Betel Nut

本研究分别从台湾槟榔病果中分离出病原菌Ar8904、Ar8905;从海南槟榔病果中分离出病原菌Ar8801、Ar8802、Ar8904以及从云南槟榔病果中分离出病原菌Ar8901、Ar892。将这些病原菌进行对比实验。研究结果表明,这7株病原菌在菌株形态、培养形状、寄主范围、致病性以及症状特征都十分的相似。因此,根据炭疽菌现代分类标准,我们可以初步确认台湾、海南、云南的槟榔病果均为同一种炭疽菌引起的。

In this study,pathogen Ar8904,Ar8905 were isolated from rotten betelnut in Taiwan Province,pathogen Ar8801,Ar8802,Ar8904 were isolated from rotten betel nut in Hainan Province and pathogen Ar8901,Ar892 were isolated from rotten betel nut in Yunnan Province.Several contrast experiments for the seven strains showed that the morphology,cultural characteristics,host range,pathogenicity and symptom characteristics of the 7 strains are very similar.Therefore,according to modern classification criteria of the colletotrichum,we could determinate that these pathogens isolated from Taiwan province,Yunnan province and Hainan province are the same species of colletotrichum.The rotten fruit disease of betel nuti is caused by the colletotrichum.
