Popis: This study was set up to identify critical maturity indices affecting storage potential of apricots and demonstrate the potential for using non-destructive measurements to segregate harvested crops for sequential marketing. Fruit of two apricot ( Prunus armeniaca ) cultivars (‘Clutha Gold’ and ‘Genevieve’) were harvested and stored for four weeks at 0 °C followed by four days of simulated shelf life at 20 °C. Fruit colour, acoustic firmness, impact firmness, flesh firmness (FF 0 ), dry matter content and soluble solids content measured non-destructively at harvest were correlated to the flesh firmness measured at the end of refrigerated storage and simulated shelf life (FF Final ) through stepwise regression. The regression models indicated that FF 0 is a predominant factor determining FF Final . According to the exponential model describing the relationship between FF 0 and FF Final , ‘Genevieve’ and ‘Clutha Gold’ could be stored at 0 °C for four weeks if harvested at firmness above 47 or 56 N, respectively. Segregation of harvested crops according to FF 0 estimated from VNIR would enable sequential marketing of fruit according to storage potential to reduce fruit loss.
