摘要
The causal fungus of pear scab, Venturia nashicola, grows slowly and rarely produces conidia on artificial media in the laboratory, but it produced conidia on the Cheongah medium containing Cheongah powder. V nashicola grew too slow to produce conidia until 15 days after cultivation but produced conidia with 4 x 10(4) conidia/plate 30 days after cultivation on the Cheongah medium containing 1% Cheongah powder. V nashicola showed a peak production of conidia with 4.5 x 10(5) conidia/plate 60 days after cultivation on the carrot medium containing 2% carrot powder, one of the constituents of Cheongah powder. The carrot medium is considered to be the best medium to obtain conidia of V nashicola in the laboratory until now. This is the first report on the development of a suitable medium for conidia production of V nashicola, as far as we know.
