Fusarium moniliforme detected in seeds of corn and its pathological significance.
All the maize samples tested were infested by F. moniliforme [Gibberella fujikuroi] at rates of 6-79.5%. Severely infected samples showed poor germination in blotter tests. The fungus was present in tip caps, pericarps and endosperms and also in embryos. Heavy infection caused severe seed rot and seedling blight when seed was sown in soil, but many plants from lightly infected seeds grew without any symptoms. However, the fungus was frequently detected from inside the stems of healthy looking seedlings. These results indicate systemic transmission from seed to plant. In inoculation experiments, G. fujikuroi produced stem rots on maize plants 110 d. The cv. Hwangok 3 was more susceptible than Suweon 19.
