English Abstract

A field experiment was carried out in a private vineyard located at Atrush village, Duhok governorate, Kurdistan region, Iraq, during 2015 growing season to investigate the effect of tipping, lateral shoots removal, spraying of three concentrations (0, 250 and 500 mg.l-1) of CCC and their interaction on growth, yield and quality of ' Taifi' grapes.

The results indicated that Tipping and both concentration of CCC significantly decreased shoot length; while removing of lateral shoots significantly increased shoot length.

Tipping significantly increased leaf area, total chlorophyll content, number of clusters per vine, yield as well as TSS and total sugars percentage, whereas removing of lateral shoots significantly increased cluster weight, TSS and total sugars percentage.

Spraying of CCC also have significant effect since increasing concentration tend to increasing number of clusters, cluster weight, yield and TSS and total sugars percentage.

The interaction between the studies factors varied in their effect on the traits, the most important interaction was the interaction of tipping + removal of lateral shoots + spraying of CCC.
