Abstract
The relationship between Fe nutritional status and Verticillium wilt disease in tomatoes possessing single gene resistance to Race 1 of Verticillium dahliae was investigated using hydroponic culture media. Iron limiting conditions increased the sensitivity of resistant tomatoes to the pathogen as expressed by wilting and chlorosis. Distance of fungal vascular invasion was approximately the same in both Fe replete and Fe limited treatments. Comparison of near-isolines revealed that the magnitude of disease expressed in Fe deficient Pixie II (resistant) was considerably less than that expressed by the susceptible Pixie variety. Infection of tomato did not enhance the severity of low-Fe stress as quantified by root peroxidase activity and chlorophyll content of young leaves.
