Effect of gas composition on the chilling injury of cucumber under the storage of low temperature

The “Green 1” cucumbers were adopted as the experiment material and the temperatures of 4℃ and 7℃ were adopted as storage temperatures.The purpose of study was to observe whether the composition of the gas could make a difference on the chilling injury of the cucumbers.The index that related to the chilling injury ——— chilling injury index, chilling injury incidence, malondialdehyde content, catalase ( CAT) activity, membrane permeability, peroxidase ( POD) activity were mainly observed. Results showed that the gas composition had significant effect on chilling injury, among them, the best gas composition was 5% O 2 and 1% CO 2.Therefore, when the cucumber were transported in the temperature that could lead to chilling injury, the chilling injury could be lightened by controlling gas composition.
