Abstract

                                The effect of culture media, carbon sources, nitrogen sources, temperature and pH on the mycelial growth of Fusarium oxysporum f.sp.cepae was investigated. The fungus grew the best on Czapek’s dox medium and glucose was the best source of carbon whereas peptone was the best source of nitrogen. Growth was maximum at 30°C which was reduced drastically below 20°C and above 35°C. The most suitable pH for optimum growth of fungus was 6.5.

Key words : Culture media - Carbon and Nitrogen sources - pH- Temperature - Fusarium oxysporum f.sp. Cepae
