Özet
This study was carried out to assess the effect of methyl jasmonate (MeJA) applied at different concentrations (0.2 mM and 0.4 mM) after harvest on nut quality characteristics of the 'Erfelek' chestnut cultivar during cold storage. Chestnuts were kept at 0 +/- 0.5 degrees C and 90 +/- 5% relative humidity for 80 days. As a result of cold storage, it was observed that the MeJA treatment had a positive effect on nut quality compared to the control. The effect of 0.2 mM MeJA treatment on weight loss, moisture and firmness values of the chestnuts was more significant than other treatments. While vitamin C, total phenolic and antioxidant activity (DPPH and FRAP assays) were similar between MeJA treatments, they were significantly preserved compared to the control. In addition, at the end of cold storage, the highest protein and the lowest ash content, which is important for nutritional quality, were observed in chestnuts treated with MeJA. On the basis of the results, we can conclude that MeJA treatments can be used as an effective tool to maintain post-harvest quality losses in the 'Erfelek' chestnut cultivar and to protect bioactive compounds during cold storage.
