Postharvest studies of resistance to gas diffusion in McIntosh apples.

Low oxygen injury (LOI) in controlled atmosphere (CA) storage was positively correlated with fruit resistance to gas diffusion (R) at harvest in McIntosh apples. In contrast to early harvest, late harvest resulted in lower R values at harvest and after storage. The longer the fruits were held in CA storage, the lower the R value. R was negatively correlated with whole fruit volume after storage, but not at harvest. R was negatively correlated with respiration rate at harvest, when respiration and R were high, but not after CA storage, when respiration rate and R were low. R increased and fruit volume decreased during storage at 80% RH, whereas the opposite occurred in a high RH (>95%) environment. In comparison with other strains of McIntosh, Marshall McIntosh had higher R values and enhanced susceptibility to LOI. At the same concentrations of fruit internal O2, Marshall McIntosh accumulated 10-fold more ethanol than did Rogers McIntosh, which indicated different thresholds for anaerobiosis in these 2 strains.
