Arbuscular mycorrhizal fungi of the Brda river valley in the Tuchola Forests

Abstract

The occurrence of arbuscular mycorrhizal fungi (AMF) associated with 19 plant species from 12 families growing in the Brda river valley in the Tuchola Forests is presented. The most frequently investigated plans were those from the families <i>Cupressaceae</i> and <i>Plantaginaceae</i>. Examination of trap cultures established from rhizosphere soil-root mixtures of the plans sampled revealed 20 described species of AMF, two undescribed <i>Glomus</i> spp., and three species of the genus <i>Glomus</i> that were difficult to recognize. The dominating AMF were members of the genus <i>Glomus</i>. Among the AMF found, <i>G. claroideum</i> was present, a species recorded for the first time in Poland. The distribution in Poland and in the world of the AMF encountered is shown.
