Results of a ten-year study on the suitability of one-wire training for wide-spaced, high-trunked plantation of grapevine
During 1977-1986, investigations were carried out in the low-rainfall region of Krems, Lower Austria, to compare two training methods. Green Veltliner vines on Kober 5 BB rootstock, growing in a wide-spaced vineyard (3.4 m x 1.2 m), were trained to horizontal bilateral cordons, either by the traditional Lenz-Moser system with a trunk height of 1.35 m and trellis support by three pairs of wires, or according to the recently popularized one-wire system (reversal upbringing, high cordon), with a stem height of 1.70 m and just one wire supporting the espalier.
From the results obtained, it was obvious that the Moser training system resulted in an enlarged leaf area with better distribution and improved light exposition of the leaves. The fruits were healthier and less affected by Botrytis cinerea, Oidium tuckeri and stiellaehme (grape peduncle necrosis). Accordingly, a high grape yield of good quality was achieved compared with the onewire training system.
No differences could be traced between the two training systems with respect to expenditure of time, labour and money.
Suggestions were made for improving the one-wire training system in order to obtain optimum benefits.
