Abstract:
The investigation was carried out to study the influence of cane biochemical content on yield and quality of Red Globe grapevines grafted on different rootstocks during the year 2018-19 and 2019-20. The cane biochemical parameters such as total phenol, carbohydrate, protein and proline content were analysed before fruit pruning whereas, yield and quality parameters such as number of bunches per vine, berry weight and berry diameter were recorded at harvest. The highest cane total phenol, carbohydrate and protein content were recorded in vines grafted on Dogridge rootstock. Whereas, highest proline content was recorded in vines grafted on 110R rootstock. The maximum berry weight and berry diameter were noted in vines grafted on Dogridge rootstock while highest number of bunches were found on Red Globe grapevines grafted on 110R rootstock for both the years of study. The present study revealed that rootstocks had significant effect on cane biochemical contents, yield and quality parameters, Red Globe vines grafted on rootstock proved better for biochemical, yield and quality parameters while Red Globe own rooted vines recorded lowest performance. Higher cane biochemical content before fruit pruning clearly indicates the nutrient and storage status of vine. The higher cane storage results into the improved and quality grape production.
