摘要
报道了东北地区水稻小球菌核菌无性世代的分生孢子——双曲孢属(NakataeasigmoidaeHara),并对其人工培养条件进行了初步的探讨。结果表明,自然光照能促进该菌产生分生孢子,在自然光条件下,病原菌在水琼脂培养基上产生分生孢子,生长物质和微量元素均不能促进孢子产生,碳氮比对菌核萌发直接产生分生孢子有影响,其中10∶1时产孢率最高,为54.23%。
Nakataea sigmoidea Hara-vegetative progeny of sclerotium oryzae was reported firstly in northeast of China, condition of artificial culture was studied. The result suggested that natural lighting can stimulate production of conidia, many conidium were produced on water agar medium under natural lighting. Growth substance and microelement can not stimulate the production of more conidium. C/N ratio has effect on sclerotia producing conidium, percentage of producing conidia was 54.23% when the ratio of C/N was 10∶1.
