- Dryness resistance
It depends on soil texture and structure but also on rooting
of the stock which may be running (less resistant) or plunging
It must be appropriate to the soil fertility and to the
final product you wish to obtain: cru, appellation or vin
de pays. It may also be determined according to special specification
data made up between the producer and the one who launches
the product. (see
VITIPRO members have mother grapevines and grafts at their
disposal that allow them to realize lots of different assemblings
in order to come up at best to the winemakers needs.
Choosing a stock for grafting that corresponds at best
to your soil and climate is of the utmost importance if you
want your vineyard plantation to thrive.
The most important limiting factors are:
- Limestone resistance
Limestone resistance is determined by 2 values : the
percentage of active calcium and the IPC (Indice de Pouvoir
Chlorosant - chlorose provoking factor). The percentage of
active calcium contains only the fine and soft elements of
calcium carbonate that are harmful to the grapewine and cause
freezing of iron, that means chlorose. Furthermore, certain
soils with an important percentage of calcium may show in
the same time a lack of iron easy to extract. Depending on
the type of stock for grafting, this may increase chlorose
risk. The IPC measures this risk.
In order to meet with your needs, VITIPRO offers
you a complete range of grapewine varieties, as there are:
