The Influence of Environmental Factors on Cultural Characters of Fusarium Species

Abstract
Single spore cultures of 8 of the 9 species of Fusarium were grown on potato-dextrose agar under fluctuating light and fluctuating temperature, fluctuating light and continuous temperature, continuous light and fluctuating temperature, continuous light and continuous temperature, and continuous darkness and continuous temperature. The optima for sporulation and development varied with the different species, but diurnal fluctuation in light and in temperature appeared to be favorable to all of them.
