Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1~5.9, the optimum pH for sporulation ranged 5.0~6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.
首先,研究了茶云纹叶枯病病菌的生物学特性;其次,通过田间抗性调查和室内人工接种鉴定,对 13 个茶树品种进行了抗病性鉴定;第三,在前人研究的基础上,对茶树抗病机理作了更深入的研究,结果发现: 1 病原菌的生物学特性病原菌的分生孢子萌发的最适温度范围为 24~27℃,菌丝生长的最适温度范围为 22~30℃;致死温度为 55℃;菌丝生长的最适 pH 范围为 5.1~5.9,孢子萌发的最适 pH 范围是 5.0~6.0;光照对病菌生长速度及分生孢子萌发影响不大,但对其产孢的影响很大,特别是有光照与无光照处理之间差异显著,光照有利于分生孢子的形成。
