从普通油茶青枯病株的根部、茎干部分离得到的致病菌,经鉴定病原菌为青枯假单胞菌,即Pseudomonas Solanacearum Smith。菌体短杆状,极生鞭毛通常1—4根。其形态和部分生理生化特征与油橄榄、蝴蝶果青枯病病原菌基本一致。感病油茶植株可呈急性萎蔫失水和慢性黄化落叶两个类型。每年4—5月病情逐渐加重,6—9月为发病高峰。 The pathogen isolated from the root and stem of common Camellia oleifera wilt disease strain was identified as Pseudomonas solanacearum by Pseudomonas solanacearum. Short rod bacteria, polar flagella usually 1-4 root. Its morphology and some physiological and biochemical characteristics and olive, butterfly fruit bacterial wilt pathogens are basically the same. Infected Camellia oleifera plant can be acute wilt dehydration and chronic yellow leaves two types. 4-5 months each year the condition gradually aggravated, 6-September peak incidence.
