De Nova Agro offers its clients Universal Rootstocks.
All plants (rootstocks) are obtained by in vitro micro-propagation. They are indentical (clonal) plants free of viruses and diseases.
In vitro propagation of 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 from pathogens.
Currently, we have the following clonal universal rootstocks: Garnem, Myrobalan, GF 677 and Controller.
Prunus dulcis x Prunus persica clonal hybrid
Middle strength root rootstock
Good connectivity to soil
Show a goods plant growth process
Attuned to heavy texture soils
Resistant to groundwater
Graft compatibility with peach and nectarine types is good
Makes positive effect on the fruit quality of the type which is grafted onto
Resistant to bacterial crown gall nematode.
Planting distance can be adjusted as 5 x 3,5 m
Myrobalan’s hardiness and ability to adapt to a wide range of soils make it an excellent rootstock. It is shallow rooted, yet well anchored and vigorous. Trees on Myro will eventually be free-standing, but may benefit from staking for the first few years, especially in lighter soils or windy conditions. It will produce a tree with a mature height of 16-20 feet. As a seedling, is not an especially precocious rootstock, and trees will take four-five years to become productive.
Apricots and almonds can be grown on Myrobalan plum rootstocks. Bob Purvis of Purvis Nursery notes, however, that delayed incompatibility has been reported with some apricot varieties, with three-four year-old trees snapping at the graft union under strong winds. Suckering at the base of the tree can also be evidence of partial incompatibility, which has been reported for Ilona apricots on Myro rootstock.
Myro has good resistance to crown gall and root knot nematode, fair resistance to phytophthora, and it is susceptible to oak root fungus.
It is recommended to make large volume orders a year ahead. The prices on Universal Rootstocks are negotiable. Please call us for further details. De Nova Agro Team is always delighted to answer your questions.
