Ethylene was produced when isolates of Botrytis cinerea derived from kiwifruit, strawberry and blueberry fruits and grape and camellia leaves were grown on a modified Pratt's medium containing 35 mM methionine in shaken or static cultures at 22 deg C in the dark. Cultures grown on Pratt's medium containing glutamate or alpha -ketoglutarate produced no more ethylene than cultures grown on basal medium alone. Optimum growth occurred at pH 3.5 and 4.5 for shake and static cultures, respectively. When B. cinerea was grown in a methionine-amended basal medium, maximum production of ethylene occurred after 3-4 days of incubation. However, maximum ethylene production per unit dry weight of mycelium (780 micro l g-1 h-1) occurred within 48 h of inoculation, after which it declined. High ethylene production from such small amounts of mycelia suggests a possible role for fungal-produced ethylene in B. cinerea pathogenesis of sensitive fruits such as kiwifruits.
