Abstract

The evaluation of physical and chemical aspects of peach fruits destined to fresh consumption varies between crops. This variation depends on many factors, but mainly on the growth conditions imposed by the environment. The objective of this study was to evaluate the physical and chemical qualities of fruits from sixteen different peach cultivars produced during three seasons in Viçosa-MG. The following cultivars; Aurora 2, Baroness, Biuti, Colibri, Coral, Crystal, Delicious Early, Prince Flower, Joia 4, Lake City, Marli, Iataquera Pearl, Rubimel, Talisman, Tropical and Tropic Beauty were grafted on Okinawa rootstocks at the experimental orchard of the Federal University of Viçosa, Viçosa-MG in 2008. The cultivars were evaluated on color characteristics of the exocarp (b * h °), mesocarp color (b * h °), fruit weight (g) polar diameter (mm) , equatorial diameter (mm), sutural diameter (mm), Firmness pulp (N), soluble solids content (Brix), Vitamin C (mg / 100g), titratable acidity (% malic acid), Carotenoids (mg / 100g ) and ratio (soluble solids content and titratable acidity ratio) during the harvests of 2011, 2012 and 2013. The experiment was carried out in a completely randomized design with sixteen treatments, three replications and 10 fruits per plot. There were differences between the characteristics evaluated from the three seasons, being Flordaprince the cultivar with the most intense exocarp color as well as higher vitamin C content.
