| 摘 要： | 对尖孢镰刀菌石竹专化型(Fusarium oxysporum f.sp.dianthi)的生物学特性进行了研究。结果表明,菌落在所供试的培养基上均能够生长,能有效地利用各种碳氮源,以蛋白胨为氮源和可溶性淀粉为最适合碳源。菌落在4～35℃范围均能生长,最适合温度为25℃。在pH 2～9的范围内都能生长,最适合pH 6。全光照条件下生长得最好,全黑暗的条件下生长得最慢。孢子的致死温度为65℃,10 min。生物学特性显示,该菌是一类对营养需求不高,对环境适应力强的病原菌。

| Abstract: | Biological characteristics of the pathogenic fungus causing wilt disease in carnation were studied. The results showed that Fusarium oxysporum f. sp. dianthi could grow on all media tested. It could also effectively use all kinds of carbon sources and nitrogen sources. The optimal carbon source is soluble starch and the optimal nitrogen source is soya peptone. The fungus could grow under 4-35 ℃ with the optimum at 25 ℃ and pH2-9 with the optimum at pH6. The growth of the fungus could be enhanced by all day light, but it grew very slowly under dark condition. The spore could be killed at 65 ℃ for 10 min. The pathogen had strong adaptability to the environment in view of its biological characteristics. |
