This thesis is the result of research at Marquette University on chrysanthemums during the past year. The specific problem was to study the development and the effect of three species of Fusarium fungi in chrysanthemum stem tissues. One of the species, Fusarium oxysporum f. conglutinans, was known to be the cause of serious infection of chrysanthemums. The other two were well known facultative parasites which had never been reported as infectious to chrysanthermums. This treatise covers the procedures and methods used in the study.
