Studies on Prediction of Sugar/Acid Ratio in Grapes

It could be concluded from the above discussion that maturity coefficients, and no. of days to maturity in particular are the most useful characters in forecasting the sugar/acid ratio of grape berries (with R² value 72 to 94 per cent. In the absence of the above characters, the leaf nutrients help to predict the sugar/acid ratio to the extent of 89 per cent while with shoot measurements, this value is 79 per cent.
