| Abstract: |
| Taking the appearance color as standard，the harvest maturity of dragon fruit was judged. By observing
the time of putresce and the change of decay rate of dragon fruit stored in normal temperature and cold storage，and
comparing the content change of soluble solid，total sugar，titratable acid and Vc，the suitable harvest stage of dragon
fruit was determined. The results showed that the storage time of maturity Ⅰ，Ⅱ harvest fruit prolonged 2 days than
maturity Ⅲ harvest fruit stored in normal temperature，and prolonged 9-10 days in cold storage. The quality of maturity
Ⅱ harvest fruit was the best after stored 10 days in normal temperature，while the fruit putresce，the quality of maturity
Ⅱ harvest fruit was better than maturity Ⅰ，Ⅱ harvest fruit stored in cold storage. Maturity Ⅱ was the suitable harvest
stage of dragon fruit. |
