The controlled mycorhization laboratory of ROBIN Pépinières

Pierre Cammalletti Technical Manager Claire Cotton Assistant

ROBIN Pépinières has developed controlled mycorhization in their own laboratory, in a constant desire, to innovate and improve the quality of its productions.

The development of controlled mycorrhiza- tion was carried out within the framework of European programs, with the help of ANVAR and in collaboration with:                 

  • INRA                                      
  • the CEMAGREF
  • CNRS Nancy
  • the University of Diepenbeck (Belgium)
  • University of Cologne (Germany)
  • University of Krakow (Poland)
  • Kiev University (Ukraine)
  • Budapest University (Hungary)
  • the IPLA (Institute of the Piedmont Region Italy)

What is a mycorrhiza?

The etymology of the word Mycorhize comes from the Greek Mukes (mushroom) and Rhiza (root). A mycorrhiza is a symbiotic association between a fungus and a root of a host plant (FRANK 1885).

There are different types of mycorrhizae, but our work focuses on:



  • Ectomycorrhizae affect only 3 to 5% of terrestrial plant species, but they have considerable forest importance:
  • They have a more or less specific specificity of plant host and soil.
  • They are of interest for the production of edible mushrooms.
  • They are directly recognizable by observing the mycorrhizal root systems with a magnifying glass.

Endomycorrhizae represent the most common form of symbiosis, they colonize more than 90% of terrestrial plants. They concern particularly ornamental or fruit species but they are also associated with forest species:

  • Ash (Fraxinus)
  • Maple (Acer)
  • Walnut (Juglans)
  • Prunus, ...
Ectomycorrhizae concern mycorrhizal fungi with interest:
  • Foresters such as: Laccaria, Hebeloma, Suillus, Paxillus, Rhizopogon, Pisolithus. On a wide range of conifer or hardwood hosts.
  • Edible such as Lactarius (Lactarius), Boletus (Suillus, or Boletus), Amanita (Ammanita), Chanterelle (Cantharellus), Perigord black truffles (Tuber melanosporum), Burgundy truffle (Tuber uncinatum), White summer truffle (Tuber aestivum), White Truffle from Italy (Tuber magnatum).
  • On a panel of hosts more or less specific in the genera Pin (Pinus), Spruce (Picea), Fir (Abies), Oak (Quercus), Hazel (Corylus), Chestnut (Castanea), Linden (Tilia), Poplar ( Populus), Cedrus (Cedrus) ...

Isolation of strains

The activity of our laboratory under the controlled Mycorhization program involves various stages of isolation of the strains until the final control of the plants before shipping.

This work allows us to be currently the only nursery in Europe able to control all stages of production and control of mycorrhizal plants with different fungi on a wide range of host species for different types of uses.
