. Low
O2 and elevated CO2 can significantly reduce the ripening and
senescence rates primarily by reducing the synthesis and
perception of ethylene changes in respiration and starch, sugars,
and chlorophyll, and changes to cell wall constituents during
ripening and/or senescence can be reduced by eliminating
ethylene action through the use of low O2/high CO2 atmospheres
(Abeles et al., 1992). According to Hong and Gross (2001), it seems
that O2 may be more important for ethylene production from
tomato slices under MAP at 5 C than CO2.
