The reason why the plant respiration tester needs to be verified is because people think that when fruits and vegetables are put into a refrigerator, they will avoid the heat generated by light under the condition of no lighting, reduce photorespiration, reduce the physiological metabolism of fruits and vegetables, and facilitate the storage and transportation of fruits and vegetables. However, in the actual storage and preservation process, the respiratory intensity is really reduced, and no relevant report has been studied and verified.
The plant respiration tester has a net volume of fruit and vegetable temperature controlled test chamber with a net volume of 23m3. The temperature control accuracy is ±0.5°C. The respiration intensity is measured with a portable plant respiration apparatus. Set the air flow rate to 0.4 L/min, and randomly select an appropriate number of representative isolated vegetable individuals as the respiration test material, measure three times, average the values, and measure the temperature at the same storage temperature.
Under 1800lx illumination and darkness, two different environmental conditions have significantly different effects on the respiration intensity of isolated green peppers after harvest. Under each temperature gradient, compared with the dark treatment, the breathing intensity of the green peppers after light treatment showed a decreasing trend. At a temperature gradient of 20°C, the respiratory intensity measured by the plant respiration apparatus was 65.84216 mgCO2/(kg·h) for dark peppers and 48.47806 mgCO2/(kg·h) for light treatment. The difference was extremely significant.
At a temperature gradient of 10°C, the respiratory intensity of the dark peppers was 26.86624 mgCO2/(kg·h), while the phyto-respirometer showed a decrease of 18.91049 mgCO2/(kg·h) after light treatment. Different light conditions have significantly different effects on the respiratory metabolism of isolated fruit and vegetable green peppers (green). The postharvest treatment of green peppers has a significantly lower respiratory intensity than darkness, and proper illumination can be used to reduce postharvest leaves Green pepper breathing metabolism.
