Resumen
Descripción
A field trial was conducted to determine the effect of cane thickness on berry quality and other biochemical parametersin ‘Tas-A-Ganesh’ grape at National Research Centre for Grapes, Pune, during the year 2008- 2009. Average bunchweight increased with increase in cane diameter. Own-rooted vines of cane thickness <6mm sprouted earlier thanthicker canes. TSS of berries decreased with increase in berry size. Berries on grafted vines recorded lower TSSthan on own-rooted vines. Biochemical parameters such as content of reducing sugars, carbohydrat and phenols werehigher in grafted vines of cane thickness >10mm. Results indicate that thicker canes either on their own roots or ongrafted vines are superior for yield and yield components, as also for physical properties of bunches and berries andtotal carbohydrate content of the canes.
