作者在油桐枯萎病病原菌的分离、鉴定、寄主范围及生物学特性等方面作了研究,认为:从其形态特征看,应属尖孢镰刀菌,从寄主范围看,未发现此菌为害其它寄主植物,尖孢镰刀菌的其它专化型和茄病镰刀菌(Fusarium solani)也很少为害油桐。作者建议将油桐枯萎病病原菌命名为尖孢镰刀菌油桐专化型(Fusurium oxysporum Sehl.f.Sp.aleuritidis f.Sp.nov)。 油桐枯萎病病原菌孢子能在pH 3—12范围内的清水中正常萌芽。相对湿度低于80％孢子不能萌芽。孢子萌芽的最适温度为25—30℃。病原菌生长对碳,氮,磷素无特殊要求,但氮素为病菌生长所必需。
The author studied the isolation, identification, host range and biological characteristics of the pathogen of Fusarium wilt, and concluded that Fusarium oxysporum should be considered from its morphological characteristics and not found from the host range Other host plants, Fusarium solani and Fusarium solani also seldom kill the tung tree. The authors propose to name the strain of Fusarium wilt pathogen Fusurium oxysporum Sehl. F. Sp. Alexuridis f. Sp. Nov. Oilseed Fusarium wilt pathogen spores can germinate normally in clear water at pH 3-12. Relative humidity less than 80% spores can not sprout. Spore germination optimum temperature is 25-30 ℃. Pathogen growth on carbon, nitrogen, phosphorus no special requirements, but nitrogen is necessary for the growth of germs.
