[目的]探讨不同碳源、氮源对花生网斑病(Phoma arachidicola Marasas Pauer & Boerema)菌丝生长的影响。[方法]以花生网斑病病菌菌种为供试材料,比较了在不同碳源、氮源培养基处理下花生网斑病菌丝的生长速率。[结果]适宜菌落生长的最适碳源为果糖、山梨醇,其次为可溶性淀粉、木糖;适宜菌落生长的最适氮源为硝酸钙,其次为硝酸钾、甘氨酸。[结论]该研究可为研究花生网斑病的发生机理提供理论基础。
[Objective] The research aimed to discuss the effects of different carbon and nitrogen sources on mycelial growth of Phoma arachidicola Marasas Pauer & Boerema. [Method] With the pathogen of Alternaria variabilis as test material, the growth rate of A. melasha on mycelium of Alternanthera philoxeroides under different carbon and nitrogen sources was compared. [Result] The optimal carbon source for suitable colony growth was fructose and sorbitol, followed by soluble starch and xylose. The optimum nitrogen source for suitable colony growth was calcium nitrate, followed by potassium nitrate and glycine. [Conclusion] This study may provide the theoretical basis for studying the pathogenesis of pelargonidosis.
