Physical and Chemical Attributes of Peach Cultivars Grown under Ecological Conditions in Van

摘要

This study was earned out to determine fruit characteristics at different harvest periods of 'Halehaven', 'Dixired', 'Glohaven', 'Jeferson', 'J.H. Hale', 'Redhaven', 'Earlyred', 'June Gold' and 'Blake' peach cultivars grown under ecological conditionsin Van province during 1999 and 2000, and also to estimate their suitable harvest times Fruits were harvested at five days intervals in 1999, and at three days intervals during 2000. In the cultivars, phenological properties, physical traits and chemical analyses were determined for two years Fruit weights varied to cultivars, harvest times and years In 2000, 'J.H. Hale' (94.0 g), 'Blake' (86.2 g), 'Redhaven' (79.2 g) had the highest fruit weights. In 1999, fruit weights in the majority of cultivars were lower than those in 2000 In both years, 'Earlyred' had the highest total soluble solid content: 17.2 % in 1999 and 19 2 % in 2000. This cultivar was followed by 'Redhaven' with 16 2 % and 'Dixired' with 16 2 % in 1999. The soluble solid contents werelower than those of the first year, depending on cultivars and on harvest times. Titratable acidity varied from 0.14 % ('Dixired', 1999) to 0.88 % ('Halehaven', 1999). In both years, harvest time for 'Earlyted' was earlier than that of other cultivars.
