Sažetak
Sorbitol and sugar composition in fruits were investigated in 6 different plum cultivars during ripening. The fruits were harvested at different maturity stage in the experimental orchard of the Agricultural Institute Osijek. Sugars (glucose, fructose and sucrose) and sorbitol in fruits were identified and quantified by high performance liquid chromatography (HPLC). Significant differences were found between sucrose, glucose, fructose and sorbitol depending on harvest date and on cultivar. The amount of sorbitol and sugars in fruits significantly increased during maturation. The individual sugars, glucose and sucrose were the highest in all harvest stages. Glucose was the predominant sugar in one cultivar. Fructose content remained relatively low. Plums with high total sugar content had higher content of sorbitol. The discriminant analysis (LDA) showed that plum cultivars were clearly separated according to sorbitol and sugars composition in fruit.
