The effect of a mixture of Phlebiopsis gigantea (Fr.) Jülich metabolites on mycelium growth of Heterobasidion spp. in vitro

Abstract

Introduction. Biological control against Heterobasidion root rot utilises the natural antagonistic properties of a saprotrophic fungus Phlebiopsis gigantea (Fr.) Jülich.

The aim of the study was to determine the effect of P. gigantea metabolites on mycelium growth in three Heterobasidion species found in Poland.

Methodology. Analyses were conducted on nine isolates of Heterobasidion and three isolates of P. gigantea.

Results. Secondary metabolites of the saprotroph exhibits the strongest effect on the reduction of mycelium growth in H. annosum and H. parviporum, while this effect was weakest on the mycelium of H. abietinum. Analysis of variance showed significant differences between mean mycelium size in individual experimental combinations (P<0.00001), while based on Tukey’s test 8 homogenous groups may be distinguished in terms of the effect of metabolites of P. gigantea isolates on individual Heterobasidion isolates.

Conclusions. It was found that secondary metabolites of P. gigantea isolates vary in their effect on the reduction of mycelium growth of Heterobasidion spp. in vitro.
