This research was carried out in nursery conditions of Tekirdag Research Institute,
in Turkey in 2000 year by using of 13 table grape cultivars. Experiment was
established according to randomized complete blocks design consisting of 4 replicates.
In the study, weight loss in grape berry (mg berry-1), wax layers
weight in grape berry skin (mg berry-1, mg cm-2, mg cm-3)
and skin thicknesses of grape berry (mm) were examined according to cultivars.
While the values concerning weight loss in grape berry in cultivars were differing
according to measurement dates; the lowest value from wax layer weight per grape
berry of cultivars was obtained from Cv. Dökülgen (0.004 mg berry-1)
and the highest value was obtained from Cv. Alphonse Lavalleé (0.045
mg berry-1). Among the averages concerning wax layer weight per skin
area of grape berry, the lowest value was 9.485 mg cm-2 for Cv. Yapincak
and the highest value was 16.785 mg cm-2 for Cv. Alphonse Lavalleé.
From the standpoint of wax layer weight per skin volume of grape berry, while
the lowest value was obtained from cvs. Cinsaut, Karagevrek and Dökülgen
(0 002 mg cm-3), the highest value was obtained from Cv. Hönüsü
(0.010 mg cm-3). Regarding skin thickness of grape berry, the lowest
values were 27.50 mm for cvs. Yapincak, Razaki and Tahannebi and the highest
value was 89.38 mm for Cv. Honusu.
