Postharvest irradiation affects colour development in bicoloured pome fruit.

Poorly coloured apple cv. Cripp's Pink (Pink Lady) fruits were irradiated with UVB + incandescent light (UVB + I), or high pressure sodium (HPS) light at 18 deg C for 0, 24, 48 and 72 h. Poorly coloured apple cv. Braeburn, and pear cv. Forelle were stored for 4 or 8 weeks at -0.5 deg C before irradiation. Poorly coloured pear cultivars Red d'Anjou and Bon Rouge were irradiated immediately after harvest. Red d'Anjou and Bon Rouge did not show any response to postharvest irradiation. HPS light was more effective in stimulating anthocyanin synthesis than UVB + I in Cripp's Pink apples. Low temperature during storage prior to irradiation affected anthocyanin synthesis in Braeburn. No improvement in colour was observed in Forelle after irradiation.
