While it is well known that endogenous ethylene production and produce sensitivity to ethylene decrease as the temperature is reduced (Liu, 1978),the interaction of temperature and ethylene concentration on the postharvest life of commodities is not well described or understood.In this study, we quantified the relationship between ethylene concentration, temperature and green life (i.e. the time to ripen) of Australian grown Cavendish bananas and with a smaller study of Lady Finger bananas.
