This Conference was a join activity with COST Action 924.To induce resveratrol synthesis and reduce skin browning in ‘Fuyu’ persimmons, fruit were treated directly after harvest with the following elicitors: UV irradiation, ozone, phosphonate, or acibenzolar-S-methyl and then kept for three months at -0.5 °C in air storage at around 95% relative humidity. Traces of transresveratrol were detected in the skin of the persimmons at harvest, but after treatment and cold storage this compound was not found. After shelf-life (storage plus 5 d at 20 °C), the soluble solids content (SSC), reducing and non-reducing sugars and total polyphenols were not significantly influenced by any of the elicitor treatments. Fruit treated with ozone showed a higher reducing sugar content but developed skin damage, flesh browning and small internal cavities. These results were correlated with the skin colour. Fruit treated with acibenzolar-S-methyl had the highest flesh firmness and total polyphenol content. However, this treatment had a higher skin browning index after shelf-life.engAcibenzolar-S-methylIrradiationOzonePhosphonateUVbook part
