Berry Weight, Quality and Cane Biochemistry Changes in Relation to Cane Thickness of Own-Rooted and Grafted 'Tas-A-Ganesh' Grape

A field trial was conducted to determine the effect of cane thickness on berry quality and other biochemical parameters in 'Tas-A-Ganesh' grape at National Research Centre for Grapes, Pune, during the year 2008- 2009. Average bunch weight increased with increase in cane diameter. Own-ischolar_mained vines of cane thickness <6mm sprouted earlier than thicker canes. TSS of berries decreased with increase in berry size. Berries on grafted vines recorded lower TSS than on own-ischolar_mained vines. Biochemical parameters such as content of reducing sugars, carbohydrat and phenols were higher in grafted vines of cane thickness >10mm. Results indicate that thicker canes either on their own ischolar_mains or on grafted vines are superior for yield and yield components, as also for physical properties of bunches and berries and total carbohydrate content of the canes.
