Abstract (EN): This study aimed to identify mineral markers at harvest capable of predicting internal browning disorders (IBDs) in pear (Pyrus communis L cv Rocha) during storage, and develop an IBD predictive model. Fruit from five orchards harvested at two different maturity stages were stored for 45 days in cold air (-0.5 degrees C) followed by 100 days under controlled atmosphere (CA) (1 kPa O-2 + 10 kPa CO2 at -0.5 degrees C). Concentrations of ten minerals were measured at harvest and a multivariate predictive model using this data was developed. The model explained 78% of variance in IBD incidence during storage and after validation it showed high accuracy (R-2 = 0.97; RMSEP = 7.7%). Amongst the ten analysed minerals, copper (Cu), being significantly correlated to IBD incidence during storage, was the most promising IBD marker. This type of model may be a very useful tool to predict at harvest fruit's sensitivity to IBD during storage allowing the selection of the most adequate storage conditions for the long-term storage of a fruit batch.
