Objective

To investigate the effects of different concentrations of Lonicera japonica extract on the postharvest storage quality of Pyrus ussuriensis Ruan’er fruits.

Methods

Pyrus ussuriensis Ruan’er were treated by immersion with 2%, 4%, 6% and 8% Lonicera japonica extract, using distilled water treatment as the control, and stored at 25 ℃. The ethylene release rate, respiration intensity, firmness, weight loss rate, color difference, soluble solid content (SSC), titratable acidity (TA) content, as well as the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and malondialdehyde (MDA) content were measured periodically. Correlation analysis was also conducted.

Results

Lonicera japonica extract was rich in total phenols and total flavonoids.Different concentrations of the extract inhibited ethylene release and respiration intensity, delayed the decline in firmness and the increase in weight loss rate, slowed the degradation of SSC and TA, and reduced the browning index (a*). The 6%–8% treatments showed the best effects, enhancing the activities of SOD, POD and CAT and inhibiting MDA accumulation. Correlation analysis indicated that MDA was extremely significantly positively correlated with weight loss rate and a* (P<0.001), and extremely significantly negatively correlated with firmness (P<0.001).

Conclusion

Lonicera japonica extract effectively maintains the storage quality of Pyrus ussuriensis Ruan’er, with the 6%–8% concentration treatments showing the best effects and demonstrating strong application potential.
