Abstract

The effect of some root exudates on the germination and mycelial growth of sclerotia of Sclerotium rolfsii Sacc. was studied. Root exudates of 5 – 10 days old seedlings from five plants viz: - tomato (Lycopersicum esculenta) maize (Zea mays), garden egg (Solanum melongena), pigeon pea (Cajanus cajan), and pepper (Capsicum annum) were employed for this study. The results showed that exudates from maize, tomato and pigeon pea root seedlings stimulated the germination of sclerotia of S. rolfsii while that of pepper and garden egg inhibited their germination. The age of seedlings of these plants studied had effect on the production and or potency of the root exudates in promoting or inhibiting the germination of sclerotia of S. rolfsii.
