A study on deterioration of postharvest cane.

The postharvest deterioration rates of 12 sugarcane cultivars were determined from the reducing sugar content in juice measured using the 2,4-dinitrophenol method. Plants were harvested in mid-January and piled up in fields for 4 days. The results showed that ROC20 and ROC23 deteriorated slower and ROC15 and ROC10 faster than other cultivars. ROC10 and ROC15 had a higher reducing sugar content than the other 10 cultivars 2 days after harvest, whereas ROC20 and ROC23 had a low reducing sugar content 4 days after harvest. Generally, there was a significant deterioration in the sugarcane cultivars tested. Higher temperatures hastened cane deterioration. At 30 deg C, chopped cane reducing sugar increased rapidly the 2nd day after harvest and continued to increase on the 3rd and 4th day. However, the reducing sugar content increased slowly during the 1st-4th days after harvest at 20 deg C. The amount of reducing sugar at 30 deg C was about 1.2 to 1.8 times greater than that at 20 deg C.
