Notes:
Ethylene (10ppm) dependent mediation of normal and mutant (rin) tomato fruit ripening was promoted by 100%oxygen, 3.7 pphm ozone, or their combination. All ripening indices studied (respiration, chlorophyll degradation, carotenoid accumulation, softening, and aroma development) were promoted by oxygen and/or ozone. Ozone also acted independent of ethylene in promoting chlorophyll degradation and aroma development in normal fruit, but did not appreciably affect these quality attributes in mutant fruit. Lycopene accumulation in normal and mutant fruit and aroma formation in normal fruit were promoted to a greater extent by ozone than were other ripening indices. Mutant (rin) fruit contained 27% of the lycopene that was present in normal (Rin) fruit after ripening in O2 containing 10ppm ethylene and 3.7 pphm ozone, whereas they contained only 3%of the lycopene in normal fruit after ripening in air containing 10ppm ethylene.
