Rootstock benefits
|
phylloxera resistance
nematode resistance drought tolerance Tolerance to varying soil acidity and salinity Influence scion vigor Influence fruit set Influence ripening rate |
|
|
|
Vitus riparia
|
Grows wild in riparian habitat, cool with a constant supply of water
Roots tend to grow parallel to the soil surface - susceptible to drought Tolerate wet/waterlogged soil Has very high phylloxera resistance Roots easily Grafts well Grows poorly in chalky soils Rootstock cultivar is Riparia Gloire de Montpellier |
|
|
|
Vitus rupestris
|
Likes deep gravely/rocky soils with a penetrable subsoil
Moderate lime tolerance (less than berlandieri more than riparia) Long vegetative cycle Roots and grafts well Rootstock cultivar - St George du Lot |
|
|
|
Vitus berlandieri
|
Successful in dry, calcareous soils
Thrives in infertile soils Very resistant to phylloxera Difficult to root |
|
|
|
101‐14
|
Moderate yield in cool climates, higher in warmer areas
Low vigor Poor draught resistance Low moderate resistance to alkaline soils May advance ripening May Improve fruitset |
(V. Riparia × V. rupestris)
|
|
|
Schwarzmann
|
Low‐moderate yields
Low moderate vigor High water requirements High potassium uptake Moderate lime tolerance May advance ripening and fruitset |
(V. Riparia × V. rupestris)
|
|
|
3309 Couderc
|
Moderate yields
Low vigor Drought sensitive Moderate lime tolerance Good in deep soils with a good water supply |
(V. Riparia × V. rupestris)
|
|
|
SO4
|
High to moderate yields
Moderate to high vigor Performs poorly in drought conditions Moderate to high lime tolerance Can advance maturity and fruit set if vigor managed Slender trunk‐breakage at graft with mechanical harvesters |
(V. Berlandieri × V. riparia)
|
|
|
1103 Paulsen
|
Moderate high yields
Moderate to high vigor Deep growing roots High drought tolerance Moderate to high lime tolerance Long vegetative cycle - delays maturity |
(V. Berlandieri × V. rupestris)
|
|
|
140 Ruggeri
|
Moderate high yields
Higher vigor than 1103 P High lime tolerance Long vegetative cycle - delay ripening Good in drought conditions |
(V. Berlandieri × V. rupestris)
|
|
|
110 Richter
|
Moderate yield
Moderate vigor Very high drought tolerance Moderate high lime tolerance Long veg cycle can delay ripening Syrah and Pinot noir - More susceptible to chlorosis Grenache - Excellent (Boursiquot 2009) |
(V. Berlandieri × V. rupestris)

What is Ampelography?
|
Ampelography uses the obvious and minute differences between cultivars to describe them so that they may be identified
|
|
|
|
What vine characteristics is Ampelography concerned with?
|
Hairs
Density of hairs Colors of the organs Shoot (dorsal and ventral side) Shape of shoot tip Shape of mature leaf - Chordate, wedge, pentagonal, circular, kidney shape Number of lobes on mature leaves |
|
|
|
Characteristics of Chardonnay
|
Most widely planted grape in the world
Small to medium sized clusters Vigor varies considerably by site and rootstock Over 100 clones in California, some french clones also for cooler climate, early ripening, low yield. Terpenic musqué clones also available High quality, complex wines |
|
|
|
Riesling
|
Riesling
Small clusters that are susceptible to bunch rot Good acid and ageworthy wines Vigor varies by soil‐ deep fer1le soil planted vines are hard to control Vine tends towards upright growth but long shoots Wines are fruity, minerally and acidic |
|
|
|
Sauvignon blanc
|
Sauvignon blanc
Managing vigor, canopy density and fruit zone microclimate is the key Bushy upright canopy with short shoots Avoid deep fertile soils Very susceptible to botrytis Varietal Thiol/sulfur compounds are key in aromatics‐ passion fruit, grapefruit, citrus, Grassy, bell pepper, Melon |
|
|
|
Pinot noir
|
Pinot noir
Very High quality variety Commonly cane pruned: control laterals, lateral crop, especially on moist fertile soils Sensitive to botrytis, powdery mildew and downy mildew Small clusters, low color Wines with good structure, elegance, intensity and complexity |
|
|
|
Cabernet Sauvignon
|
Cabernet Sauvignon
High vigor works with moderate cane pruning or spur pruning Offspring of Sauvigon blanc and Cabernet franc Strong tendrils Sensitive to chlorosis Small‐medium clusters and berries Wines with good tannins, acids, complex aromas and flavors Green pyrazine flavors require leaf pulling to avoid |
|
|
|
Merlot
|
Merlot
Child of Cabernet franc and Magdaline noir de Charantes Medium vigor on cane or spur pruning Drought suscep1ble Small clusters and berries Good wines, nice tannins and fruit flavors produces soft and full bodied wines |
|
|
|
Syrah
|
Syrah
Offspring of Dureza and Mondeuse blanche Small to medium clusters Long internodes for long reedy shoots/canes Produce rich wines with good color, large bodies, and low acids Sensitive to wind Sensitive to chlorosis Grows in a wide range of soils Flavors of violet, black olive and white pepper |
|
|
|
Grenache
|
Grenache
Medium to large clusters High vigor on wet soils More vigorous than chardonnay but less vigorous than cabernet Upright growth Makes quality red, rosé and even dessert wines Bunch rot a problem |
|
|
|
Gamay
|
Gamay
Same crossing as Chardonnay Pinot noir and Gouais Small cylindrical clusters Moderate vigor with upright growth Prone to early frost but with fer1le secondary buds the damage is minimized Lower vigor sites are preferred Short spur pruning is preferred to minimize fertility Growth similar to pinot Carbonic/Semi‐carbonic maceration |
