Abstract:
Exposure of Colletotrichum gloeosporioides conidia placed on avocado wax and on intact avocado to 45 μl of ethylene per liter stimulated spore germination, appressorium formation, and proliferation. Exposure of immature cultivar Fuerte avocado fruits inoculated with C. gloeosporioides to 45 μl of ethylene per liter enhanced appressorium proliferation and an early climacteric but did not affect lesion growth during 20 days following the treatment. During this period fungitoxic concentrations of the antifungal diene in the fruit peel remained at concentrations higher than 2,260 μg/g fresh weight. Overmature cv. Reed avocado fruits inoculated with C. gloeosporioides and exposed to 45 μl of ethylene per liter showed enhanced germination, single and multiple appressorium formation, and earlier fruit ripening. Lesion development by C. gloeosporioides occurred in ethylene- treated fruits in parallel to the development in untreated fruits. Levels of the antifungal diene from the second day after harvest decreased in parallel in ethylene treated and untreated fruits. We conclude that exposure of avocado fruits to exogenous ethylene treatment induces multiple appressorium formation and fruit ripening, but it does not activate lesion development by C. gloeosporioides.
