香蕉暗双胞叶斑病病原及其生物学特性

S668.1; 文章采用致病性试验、形态学观察等方法对引起云南香蕉(Musa spp.)灰纹病的香蕉暗双胞菌进行了鉴定研究及生物学特性测定,结果表明,该菌菌丝生长最适温度为28℃,pH值为7；在全光照处理下菌落生长最快；最佳碳源为蔗糖,最佳氮源为酵母浸粉;PDA和PSA培养基较适宜菌落生长；培养温度为25℃时产孢量最大；较适宜产孢的培养基是PDA和PSA培养基；菌丝的致死温度是70℃,10 min....

Identification biological characteristics on the Cordana leaf spot in Yunnan were carried out by pathogenicity test and morphologic observation. The results showed that the optimum temperature and pH for mycelia growth were 28 ℃ and pH 7, respectively; the whole light treatments was beneficial to mycelium growth; the fungus grew better in sucrose as carbon source and in yeast extract as nitrogen source media; the mycclia growth was better in the culture medium of PDA and PSA; the optimum culture medium and temperature for sporulation were PDA, PSA and 25 ℃, respectively; and the lethal temperature for the mycelium was 70 ℃ for remaining 30 minutes.
