Abstract: In this study, the effects of different storage methods on the fruit quality of Rosa raxburghii from Lhasa area, China were investigated. Fruits were stored at room temperature (RT), room temperature with modified atmosphere packaging (RT + MAP), low temperature ((1.0 ± 0.5) ℃) (LT), and low temperature ((1.0 ± 0.5) ℃) with MAP (LT + MAP), respectively. The changes of fruit firmness, soluble solids content (TSS), titratable acidity (TA) content, vitamin C content, superoxide dismutase (SOD) activity, weight loss and decay incidence during postharvest storage were determined. The results showed that the amount of vitamin C in fruits was decreased by 69.55%, 25.91%, 41.93% and 14.47% for the RT, RT + MAP, LT and LT + MAP groups, respectively, and SOD activity by 47.99%, 24.96%, 33.98%, and 14.32%, respectively, after 6 d storage. Fruit decay occurred only in the RT + MAP group (1.78% decay incidence). The fruit quality of the LT + MAP treatment was the best since it delayed the decrease of fruit firmness, TSS, TA and fruit weight loss during postharvest storage when compared to other treatments.
