Abstract
This study was aimed to determine the effect of plastic covering on phonological stages (bud-burst, blooming, verasion, ripening) and the physical characteristics (the yield, cluster weight, cluster length, cluster width, berry weight, berry length, berry width, berry rupture point force, shoot weight, shoot length) as well as the chemical characteristics (total soluble solids, titratable acidity and sugar fractions) of Cardinal, Yalova Incisi and round seedless grape cultivars. The trial were planed as a plastic greenhouse for each variety. The greenhouse, including three lines of the vines were covered by 5.0 m in height and 8.0 m in width with UV and IR type of polyethylene, from mid-February to mid-April. Side lines were ignored due to the border effect and only middle lines of the vines were statistically analyzed by t-test for paired plots.
