Importance of low ethylene levels to delay senescence of non-climacteric fruit and vegetables.

The storage life of a 18 non-climacteric fruit and vegetable species was assessed during storage at ambient temperature (20 deg C) and low temperature (0-5 deg C) and ventilation with air containing ethylene over the range <0.005-10 micro l/litre. The storage life of Chinese cabbages and oranges was linearly extended with a logarithmic reduction in ethylene concentration. Across 23 kinds of produce, there was about a 60% extension in postharvest life when stored in <0.005 micro l/litre compared with 0.1 micro l/litre, the commonly considered threshold level for ethylene action. It is suggested that the threshold level of ethylene action on non-climacteric produce is well below 0.005 micro l/litre and that the level of ethylene that accumulates around produce in all commercial situations is always much greater than 0.005 micro l/litre. Hence, any postharvest action that reduces the accumulation of ethylene around non-climacteric produce during marketing will result in an increase in postharvest l
