This study was carried out to determine the effects of cane girdling on coloration, maturation, yield and some quality characteristics of Vitis vinifera L. cv. Flame Seedless table grape variety. Cane girdling practices were treated at pea-size stage (G2) and veraison period (G1) over two growing seasons, 2013–2014, at the facility of Manisa Viticultural Research Institute in Turkey. Cane girdling was performed on the canes after first shoot was left from the bottom and 4 mm-wide ring of bark was completely removed with a doubleded knife. On the other hand control vines were left untouched. Statistical analyses showed that TSS, berry length, colour parameters, CIRG index and anthocyanin content of Flame Seedless was significantly affected by the cane girdling treatments in both years, 2013 and 2014. In addition it was detected that any effect of girdling treatments cannot be determined statistically significant on total yield, marketable yield, titrable acidity and 50 berry weight. Total and marketable yields of girdled vines had higher value than control vines although they were not statistically significant. Furthermore it was observed 9 and 12 days earliness with G2 treatments compare to the control vines in 2013 and 2014, respectively.
