Pruning influences both the quantity and quality of the yield, by determining how many buds are allowed to remain on the vine.
Each bud puts forth a shoot, which in turn bears up to three bunches of grapes. The level of productivity depends on the vine variety and on the location of the buds on the stock.
If the crop is large, then there may be too many bunches for the vine’s ability to photosynthesize. This results in an unfavorable leaf-to-fruit ratio and makes it difficult for the grapes to ripen. In addition, because the grapes are given priority access to nutrients, the vine itself is weakened, as it cannot build up much in the way of reserves.
By contrast, if too few buds remain on the vine, then the plant does not have a sufficient outlet for its growth capabilities. Plant growth may be vigorous (with thick shoots), but the fruit crop will be insignificant. This makes no improvement to the quality of the grapes, but simply leads to a reduction in yield and income.
