Abstract
Dipping postharvest bananas in crude extract from peels of unheated green bananas (UHGB) significantlycontrolled the occurrence of diseases, while dipping in crude extract from peels of heated green bananas (HGB) had littleeffect on decay. This is the first report on the induction of disease tolerance of postharvest fruits by direct application ofcrude extract from fruits of the same species. UHGB treated Colletrotrichum musae spores were found to be weaker inpathogenicity than HGB treated ones. However, UHGB had little effect, but HGB had significant effect, on the rates of sporegermination. These results imply that the mechanism of anti-disease substances extracted from green banana peels enhancethe disease tolerance of postharvest bananas by exogenous application lies in that the anti-disease substances helpstrengthen the defensive system of fruits themselves rather than affects the pathogen.
