Enhancement of senescence in non-climacteric fruit and vegetables by low ethylene levels.

When strawberries, oranges, lettuce, beans, Chinese cabbage, bak choi [Brassica chinensis], choi sum [B. parachinensis] and gai lan [B. alboglabra] (all non-climacteric fruits and vegetables) were held at ambient temperature (20 deg C) or low temperature (0 deg -2.5 deg C) and ventilated with air containing 10 to 0.005 micro litres ethylene/litre, the storage life of all produce was found to be linearly extended with a logarithmic reduction in ethylene concentration across the whole concentration range. The ethylene level found to accumulate around produce in markets was in the range 0.06 to 1.45 micro litres/litre, suggesting that premature ageing occurs in all non-climacteric produce during normal marketing. There appears to be no benign level of ethylene so that any reduction of ethylene concentration should help in maintaining quality of non-climacteric fruits and vegetables.
