This study was conducted in order to determine the antioxidant activities of certain apple varieties. 'Galaxy Gala' , 'Scarlet Spur' , 'Fuji' , 'Pink Lady' and 'Granny Smith' were characterized in this study. The antioxidant activities among the varieties were determined via three different procedures. Antiradical activity figures of the apple varieties were between 0.592 ('Galaxy Gala') and 0.802 ('Scarlet Spur'). Inhibition levels of chelating activity with Fe +2 varied between 40.20-55.50%; 'Scarlet Spur' and 'Pink Lady' extracts had the highest inhibition with 55.50% and 'Granny Smith' extract had the lowest with the level. Among the extracts showing H 2 O 2 clearance effect, Granny Smith (62.54%) and Scarlet Spur (44.67%) extracts had the highest inhibition levels. In this study conducted on apple varieties, total phenolic matter levels were determined in 'Scarlet

Bu çalışma Sudurağı-Karaman ekolojik şartlarında M9 anacına aşılı bazı elma çeşitlerinin fenolojik ve pomolojik özelliklerinin tespiti amacıyla yürütülmüştür. Araştırmada Galaxy Gala, Scarlet Spur, Fuji, Pink Lady ve Granny Smith çeşitlerinde tomurcuk kabarması, tomurcuk patlaması, çiçeklenme başlangıcı, tam çiçeklenme, çiçeklenme sonu ve meyvelerin hasat olum tarihleri tespit edilmiştir. Araştırma sonuçlarına göre çeşitlerde tomurcuk kabarması 27 Mart-1 Nisan, tomurcuk patlaması 3-9 Nisan, çiçeklenme Determination of Phenological and Pomological Characters of some Apple Cultivars Grafted on M9 Rootstock at Karaman Ecological Conditions AbstractThis study was conducted in order to determine the phenologic and pomologic properties of certain apple varieties grafted on M9 rootstock under Sudurağı-Karaman ecologic conditions. Dates of proliferation, bud burst, commencement of blooming, full blooming, end of blooming phases of Galaxy Gala, Scarlet Spur, Fuji, Pink Lady and Granny Smith were identified in this study.
