在江西省首次发现了杉木细菌性叶枯病。其主要症状是针叶或嫩梢变褐,最后使针叶或嫩梢枯死。病原菌主要由伤口侵入,在活针叶上越冬。分离了该病原菌,并对一系列寄主植物进行了接种试验。对该病原菌的鉴定试验表明,该菌为假单孢杆菌属的一个新种,暂定名为杉木假单孢杆菌(Pseudomonas cunninghamiae sp.nov.)。 It was the first time that bacterial blight of Chinese fir was found in Jiangxi Province. The main symptoms are brownish needles or tender shoots that eventually wither the needles or tender shoots. The pathogen mainly invaded by wounds, wintering on live needles. The pathogen was isolated and a series of host plants were inoculated. Identification of the pathogen showed that the bacterium is a new species of Pseudomonas sp., Tentatively named Pseudomonas cunninghamiae sp. Nov.
