Ripening of Improved Pope tomatoes was delayed for 1 week under ambient conditions (29-33 deg C) in 0.05 mm polyethylene (PE) bags with zero to 4 pinholes for gas diffusion, maintaining high CO2 (7-12%) and low O2 (2-7%) concentrations. Increasing the number of holes to 8 and 16 greatly reduced CO2 accumulation and accelerated the rate of ripening slightly. Bags with 2-4 diffusion holes (DH) per 4 kg tomatoes gave the best results, since the very high CO2 levels in a completely sealed PE bag increased decay. Inclusion of CO2 scrubbers and C2H4 scrubbers in the PE bags resulted in large reductions in the concentrations of these gases but did not affect the rate of ripening. The ripening of tomatoes transported in wooden crates of 25-27 kg capacity form Northern Mindanao to Los Banos, Luzon was retarded when the crates were lined with 0.05 mm PE bags having 24 DH. The use of PE bags with DH without CO2 scrubbers or C2H4 scrubbers was as effective as with the scrubbers in retarding the rate of ripening during 6 days of transport and holding under ambient conditions. When the PE bag lining was completely sealed, ripening was also retarded but disease incidence was high. The physicochemical composition of the fruits was not affected by storage in PE bags with varying numbers of holes nor by the inclusion of CO2 or C2H4 scrubbers. The fruits ripened normally upon transfer to air.
