Some Physico-Chemical Properties and Antioxidant Capacities of Early Maturing Nectarine, Peach and Apricot Cultivars

In this study, some physico-chemical properties in terms of fruit weight, seed weight, fruit width, fruit length, fruit length/width, total soluble solids (TSS), pH, titratable acidity (TA), TSS/TA and fruit juice yield in early maturing nectarine, peach and apricot cultivars are assessed in Mersin region. Obtained values were respectively 116.781 g, 5.361g, 79.501mm, 79.869 mm, 0.998, 9.033%, 4.100, 0.528%, 17.121%, 110.076 g, 7.463 g, 78.285 mm, 75.600 mm, 0.991, 7.300%, 4.067, 0.744%, 9.807% and 66.468% for Flanoba nectarine; 65.765% for Francoise peach and 44.866 g, 6.587 g, 60.770 mm, 62.371 mm, 1.006, 8.800%, 4.333, 1.016%, 8.659%, and 65.611% for Ninfa apricot. However, determinated L, a, and b values considered for fruit peel color measurements are respectively 50.639, 15.556, and 20.016 for peach; 38.514, 30.185, and 16.621 for nectarine; and 52.628, 6.669 and 23.927 for apricot. However, determinated L, a, and b values considered for fruit peel color measurements are respectively 50.639, 15.556, and 20.016 for peach; 38.514, 30.185, and 16.621 for nectarine; and 52.628, 6.669 and 23.927 for apricot. When antioxidant activities of fruit cultivars in the experiments compared, Flanoba nectarine cultivar was showed the highest values.
