The goal of this investigation was to evaluate some biochemical traits(pH, total soluble solids and ascorbic acid) in fruits of ten orange(Citrus sinensis) cultivars.Studied cultivars were Salustiana, Pine apple, Number 4, Valencia, Hamlin, Early Navel, Madam Vinous, Marss, Brohen and Thompson. The results showed that there were significant differences among studied cultivars. The highest and the lowest pH were found in Early Navel (4.17) and Brohen (3.01), respectively. The highest and the lowest total soluble solids (TSS) were obtained in the cultivars Number 4(11.16%) and Brohen (7.8%), respectively. The cultivars Number 4, Pine apple and Salustiana had no significant differences for TSS (P < 0.05).The lowest pH and TSS belonged to the cultivar Brohen. The highest and the lowest ascorbic acid content were obtained in the cultivars Number 4(107.33mg.100ml-1) and Marss (56.33mg.100 ml-1), respectively. The results showed that the cultivar Number 4 can be valuable among other cultivars since it had the highest TSS and ascorbic acid. Key words: pH, total soluble solids, ascorbic acid, Citrus sinensis, Hormozgan, Iran.
