Abstract

The specificity of the Cryptococcus fagisuga and N. coccinea association is studied by artificial inoculation of 4 species of Nectria: N. coccinea, N. ditissima. N. galligena and N. cinnabarina on bark infested with beech scale. N. coccinea appears to be the most efficient species for producing necrosis at the cambial level. The composition of the bark, in relation to induced pectinase activity gives a good explanation of the specificity recorded here.
