寒地水稻立枯病病原真菌的分离鉴定

Preliminary Identification of Causal Organisms of Rice Wilt

1999～ 2 0 0 1年从黑龙江省不同地区 832株水稻立枯病病苗样品中分离获得 1318个分离物 ,经鉴定归属 7个属 12个种 ,其中Fusariumoxysporum占 19 7% ,Fusariumsolani占 2 5 9% ,Fusariumgraminearum占 17 1% ,Fusariummoniliforme占 8 2 % ,Fusariumsemitectum占 9 4 % ,Rhizoctoniasolani占 16 5 %。对分离频率较高的种类进行回接验证 。

isolates were obtained from samples of rice wilt collected from deferent regions in Heilongjiang province. They were divided into 7 genera and 10 species. Reinoculated with the predominant fungus can also cause some disease.
