Abstract:
Investigations carried out in the Avereşti wine- growing
centre, in the Huşi vineyard, pointed out that the training forms on hightrunk
and on semi-high trunk defined two different training systems. These
were different from each other by the exposable leaf area, the leaf index and
the exposure degree of the canopy to the direct solar radiation. The values
of these indicators showed that the training system on semi-high trunk had a
qualitative potential superior to the training system on high-trunk, ensuring
a more rational distribution of the young shoot within the grapevine
canopy, and a better exposure of the leaf area to direct solar radiation. Due
to these characteristics the training system on semi-high trunk allowed to
accumulate higher quantities of sugar in grapes and to obtain must with
balanced acidity.
