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 tip itself is the uppermost growth zone of the shoot, less than one centimetre long, with the apex cells, which separate new shoot segments with leaves and tendrils downwards through constant cell division.
1 = basal leaves without tendrils, 2 = grapevine, 3 = tendril, 4 = internode, 5 = shoot tip, 6 = nodes with grapes or tendrils, each with a leaf opposite, 7 = nodes without grapes or tendrils.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
