Caracterização da curva de maturação de pêssegos 'Aurora-1', na região de Jaboticabal-SP

摘要: The aim of this work was to characterize the maturation stage peaches 'Aurora-1' for region Jaboticabal, SP, Brazil. experiment conduced in a commercial orchard Vista Alegre do Alto, where branches 15 trees were marked with flowers "balloon" stage. After 20 days, fruits harvested, every 7 days (or once week) until complete (111 days). Through data height and diameter, it checked that cultivar Aurora-1 showed standard growth sigmoidal double curves reaching end 59.84 ± 6.9 mm 50.30 5.8 diameter. There development total mass fruit 41.08g 58.82g (43%) period 90 111 days. titratable acidity firmness reduced same proportion from soluble solids sugars contents increased during period. intern color developed yellow-greenish intensive yellow. base two first samplings values similar as color, orange. Yet, covering had stronger difference changing red, which is proper cultivar. These results among 97 reached their physiologic 104 they overripe.
