Ethylene at 10 and 100 μl/litre stimulated germ‐tube elongation of Botrytis cinerea spores incubated within normal and non‐ripening nor tomato fruits, but had little influence on the total percent of germination. Values of germ‐tube length within the mature‐green normal fruits and the mature‐green or mature nor fruits were similar to those recorded within the normal mature fruits when held in air. Exposure of the normal and the mutant fruits to 100 μl/litre ethylene immediately after inoculation with B. cinerea insignificantly increased lesion development, but resulted in increased sporulation. When tomato fruits were exposed to ethylene for 3 days before inoculation a marked stimulatory effect on rot development was exhibited on the mature‐green normal fruits but not on the nor mutant fruits. The results indicate that exogenous ethylene may directly stimulate germ tube growth of B. cinerea in both normal and mutant fruit, but that it may affect subsequent fungal growth indirectly, via stimulation of the ripening process, only in preclimacteric normal tomato fruit.
