Effect of mycorrhizae o f pine seedlings on the utilization of different mineral phosphorus sources

Abstract

Pine seedlings (P. sylvestris L.) growing on the unsterilized sand, with addition of different phosphorus sources, were inoculated with ectomycorrhizal fungi. Lack of P in the substrate restricted mycorrhizal infection of roots. In the presence of AIPO₄ and FePO₄ inoculation with A. verna and H. mesophaeum have positive effect on the seedlings growth and survival. Strain of H. mesophaeum intensified the phosphorus uptakc, particulary when FePO₄ was applied.
