This educational system (German Tatura grid or gate) was developed at the Australian research station Tatura (Victoria). It can belong to the two groups Trellis education and Cordon education be counted. The support structure has a V-shape that opens upwards (hence the “V-system”). In the middle of one Vine row meet the canopies of the neighboring rows, which are inclined by 60 °, and form an arbor. The system yields high Yields, but is difficult to mechanize. So it doesn't matter much. The developed in France Lyra education is very similar in principle, just a little smaller.
