Shoot tip cut

Alternative vineyard work in which the top 10 to 20 centimetres of the young shoots are cut off shortly before the vine flowers. In wire-frame training, pruning can be done mechanically when the shoots have grown beyond the top wire and can no longer be fixed. The shoot apex itself is the uppermost growth zone of the shoot, less than one inch in extent, containing the apical cells which, by continuous cell divisions, divide new shoot segments with leaves and tendrils downward.

Capping the shoot tip shortly before flowering interrupts shoot growth in favour of flower development. This can reduce the risk of trickling and promote good fruit set. A disadvantage is that by breaking the apical dominance of the main shoot, the formation of stingy shoots from the stingy buds is promoted at an early stage. More rigorous removal or shortening to a length of up to 30 centimetres is known as pruning; see Pruning. This work has a yield-reducing and quality-enhancing effect. In this regard, see thinning out as well as vineyard care.
