Biochemical compositions and nutrients changes in seeds of Cabernet Sauvignon (Vitis vinifera L.) as affected by different rootstocks

The present study, conducted to know the effect of grape rootstocks on yield, quality, seed nutrients and seed biochemicals of Cabernet Sauvignon grapevine, showed that the seed nutrients and seed biochemicals of Cabernet Sauvignon grafted on different rootstocks showed significant effect for seed nutrients. Among the rootstocks studied, the SO4 recorded high nutrient content while Gravasec recorded the lowest. The rootstock, Dogridge and Gravasec showed higher concentration of biochemicals in grape seed while lower in 1103P rootstock grafted vines. Rootstock 140Ru and Dogridge showed maximum performance for yield and quality parameters while SO4 followed by 101.14MGT, recorded lower performance for yield and quality. Use of rootstock had positive effect on seed nutrients, seed biochemicals, yield and yield parameters of Cabernet Sauvignon grapes. The results showed a positive correlation among various traits. Nitrogen had a positive correlation with Ca, protein, and phenol. Phenol was positively correlated with Ca and Mn. Proline had strong positive correlations with Na and Fe. Carbohydrate was positively correlated with Cu and Fe.
