The rate of ethylene production is greater in banana (Musa spp.) flowers having an abscising perianth (“ap”) than in those with a persistent perianth (“pp”). Treatments with ethephon did not change the type of the flowers but speeded up their senescence.
Ethylene gas promoted abscission of mature-green fruits of olive (olea europaea L.) but did not induce endogenous ethylene production. Ethylene readily penetrated and moved through olive fruits. Mature-black olives did not respond to ethylene.
Unpicked avocado fruit showed no response to ethylene treatments given at 50 ppm for 48 hr. Picked ‘Hass’ fruit did not respond to ethylene treatments given immediately after harvest. A good response was observed to treatment given 25 or 49 hr after harvest. This may be explained by assuming the existence of an endogenous factor inhibiting ethylene action.
