Abstract

The pectinase activity of Nectria coccinea was studied in vitro and in vivo in relation to the pectinases of Cryptococcus fagisuga and the nature of the bark. Any pectinases necessary for degradation of pectic material were secreted by the fungus in vitro. Some pectinases produced by the insect are of great significance in the predisposition of the bark to alteration by the fungus. The assistance given by the scale insect and the pectinase pool of N. coccinea which is well adapted to the trunk bark, is a possible explanation of the specificity of the association C. fagisuga/N. coccinea.
