Abstract
Nectria, Monilinia, Phytophthora, Botrytis and Penicillium are major pathogens of stored Cox apples in the U.K. For over 20 years postharvest application of fungicides has been relied upon for the control of storage rots and consequently the emphasis of controlled atmosphere (CA) research has been directed towards maximum retardation of fruit ripening and minimal development of physiological disorders rather than the control of fungal decay.
Although current standard CA condition for Cox apples (1.25% O2, <1% CO2) were established with little regard to effects on rot development, in previous work (Tomkins, 1966), a progressive reduction in rotting of Cox apples was achieved by decreasing oxygen concentration in the absence of carbon dioxide.
Uncertainty over the future use of postharvest fungicide treatments prompted an investigation into the effect on rot development of even lower store oxygen concentrations and ethylene removal.
Both techniques have been shown to reduce softening compared with standard CA (Stow and Genge, 1990) which may confer an increased resistance to certain fungal pathogens.
