The project provided new insights into the role of ectomycorrhizal symbioses in the resistance of young forest tress to drought stress. The work was carried out with 3 tree species: Norway spruce (Picea abies); Douglas fir (Pseudotsuga menziesii); eucalypt (Eucalyptus globulus) and a number of isolates of ectomycorrhizal fungi belonging to 6 species: Pisolithus tinctorious; Laccaria laccata; Thelephora terrestris; Cenococcum geophilum; Paxillus involutus; and an unidentified fungus forming white mycorrhizas with mycelial stands. It was found that ectomycorrhizal fungi differ in the contribution to water management by young forest trees and some of the mechanisms involved have been identified. A laboratory test was developed for assessing the protective effect of ectomycorrhizal fungi under drought stress and comparative experimental plantations with different fungal associates have been created. The first results demontrate that some fungal strains, selected with the appropriate hosts, improve survival and early growth of the plantations.
