Response of “Red Globe” (Vitis vinifera L.) to cane girdling

The effect of cane girdling on skin colour, harvest date, yield, and some quality characteristics of Vitis vinifera L. cv. Red Globe table grape variety, was measured over two growing seasons, 2013–2014, at the facility of Manisa Viticulture Research Station in Turkey. Cane girdling was performed on the spurs after first bud was left from the bottom and 4 mm-wide ring of bark was completely removed with a doubleded knife at veraison period. Statistical analyses showed that total soluble solid content, berry width, berry length, colour parameters, CIRG index and anthocyanin content of the Red Globe was significantly affected by the girdling treatment 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, total phenolics, titrable acidity, pH and 50 berry weight. Total and marketable yields of girdled vines had higher value although they weren’t statistically significant. Furthermore it was observed on girdled vines 7 and 11 days earliness compare to the control vines in 2013 and 2014, respectively.
