Abstract

In two oak stands in the north-east of Austria, the root systems of declining oak trees (Quercus petraea and Q. robur) were compared to those of vigorous trees. Ectomycorrhizal roots were morphotyped and counted. Fortysix ectomycorrhizae could be differentiated. While all morphotypes occurred in Patzmannsdorf, only 38 morphotypes were found in Niederweiden. The presence of some morphotypes was highly correlated with the crown-status of the trees. In both stands, the Shannon index of diversity calculated for the ectomycorrhizal microcoenosis was higher for the root systems of vital trees. It was possible to construct a discriminant function which discerned the ectomycorrhizal microcoenoses of vital and of declining trees. The possibility of reducing the number of morphotypes selected for the construction of the discriminant function without significant loss of information about the tree status was tested. Possible implications of the correlation of morphotypes with the crown-status of oak trees are discussed.
