不同培养条件对循化线辣椒疫霉菌产孢量的影响

Effect of Different Culture Conditions on Sporulation Quantity of Phytophthora capsici in Capsicum annuum L.var.dactylus M

[目的]探讨不同培养条件对循化线辣椒疫霉病产孢量的影响。[方法]针对光照时数、pH、培养基以及温度对循化线辣椒疫霉菌分离培养过程中产孢量的影响进行了研究。[结果]循化线辣椒疫霉菌在24 h/天光照、pH为7.0、马铃薯培养基(PSA)和30℃条件下产孢量最大,其中pH、基础培养基和温度对产孢量影响较大。[结论]为循化线辣椒在自然界发病条件方面的研究奠定了基础。

[Objective] The paper was to explore the effect of different culture conditions on sporulation quantity of Phytophthora capsici in Capsicum annuum L.var.dactylus M.[Method] The effects of illumination hours,pH,medium and temperature on sporulation quantity during isolation and culture process of P.capsici were studied.[Result] The sporulation quantity f P.capsici under the conditions of 24 h/day illumination,pH 7.0,potato medium（PSA） and 30 ℃ was the largest,and pH,basal medium and temperature had greater impact on sporulation quantity.[Conclusion] The study laid foundation for the study on natural incidence condition of P.capsici.
