ABSTRACT
Fusarium oxysporum f. sp. lycopersici, a tomato pathogen, was isolated from the stems of resistant and susceptible varieties of tomato and catbbage which had been previously inoculated by dipping injured roots of seedlings in a fungus suspension, Only the susceptible tomato variety wilted. F. oxysporum f. sp, conglutinans, a cabbage pathogen, was isolated from both tomato and cabbage stems similarly inoculated. Only the susceptible cabbage wilted. In determining the presence of fungi within he plants, surface-steri1ized sections of seedling stems were placed upon water agar. F. oxysporum sp. lycopersici grew from stems of 83% of the susceptible tomatoes, from 50% the resistant tomatoes, and from 40% of the cabbage stems. F. oxysporum f. sp. conglutinans grew from 55% of the susceptible cabbage, from 17% of the resistant cabbage, from 7% of the tomatoes. Thus epidermal or other protective structures arc not the deciding factors in determining Fusarium wilt resistance in tomato or cabbage. However, differences exist in the factors contributing to wilt resistance between these crops.
