ROBIN Pépinières HAUTE PER­FOR­MANCE® en­domy­corhizal plants

The en­domy­c­or­rhizae are the most widespread type of my­c­or­rhizal as­so­ci­a­tion found in na­ture. The pH of the soil is one of the im­por­tant fac­tors in the choice of my­c­or­rhizal species the best adapted to the plan­ta­tion site.

The ar­bus­cular en­domy­c­or­rhizae like the Glomus in­traradices that we have chosen in our lab­o­ra­tory, are in­ter­esting for many plants prin­ci­pally the de­cid­uous species of tree and shrub:

  • Érable (Acer)
  • Noyer (Juglans)
  • Cerisier à fleurs (Prunus)
  • Cornouiller (Cornus)
  • Frêne (Frax­inus)

The prin­ciple of this as­so­ci­a­tion is simple: le mi­cro­scopic fungi pen­e­trates into the root cells of the host plant and mul­tiply there, putting out(thear­bus­cules) or (vesi­cles) or­gans of re­sis­tance in fungi.

This fungi also de­velops out­side in the form of fil­a­ments. These fil­a­ments have a double role. Firstly they rep­re­sent the sur­face for ex­change with the soil and they give birth to spores (re­pro­duc­tive or­gans of the fungi). These muli­tiply in the soil and rep­re­sent the base of the new inoculum able to col­o­nize herba­ceous species as well as or­na­mental species and trees.

These sys­tems en­able the rapid de­vel­op­ment of the pro­cess of re­nat­u­ral­iza­tion. The pres­ence of fungi in the heart of roots en­cour­ages the de­vel­op­ment of plants by
mul­ti­plying the pos­si­bil­i­ties of ex­change with the out­side by making the nu­tri­tive ele­ments in the soil more ac­ces­sible to the plant. It also en­cour­ages the ab­sorp­tion of water by the plant.

A Nat­ural bi­o­log­ical stim­u­lant

The fungus si­t­u­ated in the roots does not ex­pe­ri­ence any stress during planting. Since this fungus is a nat­ural bi­o­log­ical stim­u­lant it limits the amount of com­ple­men­tary fer­til­izer re­quired

Since the my­c­or­rhizal plants are more ro­bust they are less sen­si­tive to pathogens. The young HAUTE PER­FOR­MANCE® en­domy­c­or­rhizal plants en­able an im­prove­ment in the rate of re­covery and in the young growth on sites with dif­fi­cult con­di­tions and in non-forest soils such as :

  • Quar­ries
  • Em­bank­ment land,
  • Ap­proaches to roads or mo­tor­ways,
  • Railway lines
  • Agri­cul­tural land
  • In­dus­trial waste­land...

« Ac­tu­ally, what we can say on this sub­ject is that Pépinière Robin sup­plied Haute-Per­for­mance de­cid­uous con­trolled my­c­or­rhizal plants for the re­nat­u­ral­iza­tion of
former in­dus­trial site in Toulouse. Our planting con­di­tions are dif­fi­cult and the my­c­or­rhizal Plants have been a very pos­i­tive so­lu­tion for our soil with no or­ganic ma­te­rial. For ex­ample, the parcel « bw5 », the rates of re­covery have been su­pe­rior to 95%.
In ad­di­tion, the de­livery in crates of Robin ANTI-CHIGNON® con­tainers has fa­cil­i­tated
storage on site.
We are on the whole very sat­i­fied with the ser­vices of Pépinière ROBIN.»
