De Nova Agro offers different popular Cherry rootstocks!
All the plants (rootstocks) are obtained by in vitro micro-propagation. They are indentical (clonal) plants free of viruses and diseases.
In vitro propagation of Cherry Rootstocks has a range of advantages such as:
- Fast production of identical material (all of the plants maintain the same characteristics);
- Plants produced from tissue cultures tend to develop much better and faster;
- Plants are free of pathogens.
Krymsk 5 (VSL-2 cv.)
Krymsk® 5 (VSL-2) is a semi-dwarf cherry rootstock adaptable to a range of climates. It has a well-developed fruiting root system. The rootstock is resistant to heavy waterlogged soils and bacterial cancer which makes it highly demanded on the market. Krymsk 5 (VSL-2) is an easy going rootstock in the fruit tree nursery. However, it requires virus-free graft wood and bud wood. It is suitable for heavy and wet soils, and well-known for its cold hardiness and drought resistance.
Origin: Krymsk Breeding Station Russia / Professor Dr. G. Eremin.
Hybrid : Prunus fruticosa x Prunus lannesiana.
Compatible with: sweet and sour cherries.
Productivity: early and high season production, even under dry conditions.
Cultivation features: Provides an average growth force (according to our experiments, the height of the trees at the age of nine was 3.3-3.5 m). Trees are best planted in accordance with the following scheme: 4.5-5 x 2.5-3 m; the feeding area should be 11-15m2.
Yields: over the years of fruiting, the average yield does not depend on the tree planting scheme. However, the higher profitability is noted in the scheme of 5.0 × 3.0 and 5.0 × 2.5 m. In the third year after planting, one tree may bring about 0.5-0.7 kg, and in the fifth year, this amount might increase up to13 kg. Depending on its variety, nine-year-old tree may bring 10 to18 kg of crop.
Parentage: Prunus mahaleb X Prunus avium
Description: cherry rootstock – same vigour as 60/70% of Prunus avium semi dwarfing nature
Usage: ideal rootstock for deep soils
- This hybrid rootstock is a result of a cross between Mazzard and Mahaleb (Ma x Ma);
- It is rated in vigour as 20-25% more dwarfing than Mahaleb (vigour between Colt and GiSelA 6 rootstocks);
- Maxma® 14 is compatible with most cherry varieties, quite precocious and productive;
- It is considered to be one of the leading rootstocks in use in Europe;
- Abundant root system with good anchorage;
- Maxma® 14 rootstock is tolerant to wet soils and is resistant to iron chlorosis;
- Tolerant to Pseudomonas, moderately sensitive to Phytophthora, resistant to nematodes;
- Very low suckering.
In a trial conducted on loamy soils in Oregon, the rootstock produced a tree that is slightly larger than Mazzard through the seventh leaf when combined with Bing. Therefore, it is not recommended for super high density plantings in the Northwest. Production in the fifth leaf was significantly greater with an average of 46 pounds per tree compared to only 2.8 pounds per tree for Mazzard. Maxma 14 shows broad adaptation to soil types and environmental conditions.
Chile growers were encouraged to plant MaxMa14 as it provides some resistance to bacterial canker and nematodes. Some growers in the PNW like its semi-vigorous growth habit and moderate precocity. MaxMa 14 shows good scion compatibility and a broad adaptation to soil types as well as environmental conditions. It has good tolerance to wet soils, and also performs well in calcareous soils. Crop management may be needed for productive varieties in early years.
Origin : Prunus cerasus X Prunus canescens
Gisela 6 is one of the semi-dwarf sweet cherry rootstocks. This rootstock is productive and winter-hardy which makes it the most popular rootstock for new plantings.
Even though Gisela 6 is a relatively vigorous rootstock, it is easy to manage. Typical planting densities are 300 to 500 trees per acre (740-1235 trees per hectare). Although it exhibits medium-high vigor, it is also very precocious, producing harvestable crops by the third leaf with full production possible by the fifth leaf.
High production potential continues on Gisela 6 into maturity, so proper pruning is essential to maintain adequate leaf-to-fruit ratio and good fruit size. Gisela 6 is well suited for a wide range of soil types, heavy one, in particular; however, good drainage is essential.
Origin: East Malling Research Station. Bred in 1958. Released in 1977.
This rootstock is a form of the seedling cherry Prunus avium crossed with the less vigorous Prunus pseudocerasus. It is a semi-vigorous rootstock which is good for growing cherry trees in large gardens and community orchards. Colt has good compatibility with nearly all cherry varieties, possibly excluding Van.
Trees budded on Colt vegetative rootstocks are characterized by the strongest growth and best quality. This rootstock produces a tree with a height of 12ft-14ft in European conditions and somewhat larger in North American conditions. It tolerates poorer soils and needs less looking after. It’s also useful for large cherry fans. It’s main drawback in US conditions is that it is not particularly cold-hardy.
Start fruiting: After three or four years
The height of the tree: 3.5-5 m
Resistances: Phytophthora root rot, bacterial canker, crown gall, cherry replant disease.
Soil tolerance: Tolerant to droughty soils, calcareous, clay, heavy soils. Well absorbs magnesium and calcium from the soil.
Cold resistant: medium
Spacing: 6m (20ft)
Support: Self Supporting – No structures required.
It is recommended to make large volume orders a year ahead. The price for Cherry Rootstocks is negotiable.
