Croissance et ramification du rhizomorphe d'Armillaria bulbosa(Barla) Romagn

Abstract: Résumé.· La morphogenèse du rhizomorphe souterrain a été étudiée par une méthode de culture en caisson à brouillard.Les résultats obtenus ont mis en évidence l'existence d'une hiérarchie entre les différents systèmes rhizomorphiques, reposant sans doute sur un déficit nutritionnel.Il n'existe pas de dominance apicale sensu stricto au sein d'un système rhizomorphique, car les vitesses de croissance des axes et des ramifications sont tout à fait comparables. La hiérarchie du système porte sur le diamètre des org… Show more

“…All isolates tested in the present experiments grew the “subcorticalis” form of rhizomorphs. In laboratory conditions, the “subterranean” form is usually obtained when the fungus is grown from a woody substrate in a mist chamber, as described by Tsoumou‐Gavouka and Guillaumin (1984). It would be of interest to know the role of cellulases, and especially, if there is a close link between a particular β‐glucosidase isoform and the initiation and growth of each type of rhizomorph.…”
