Influence of ectomycorrhiza Paxillus involutus (Batsch. Ex. Fr.) inoculation and fungicide treatment on Populus sp.

This study used two strains (Maj and Nau) of the ectomycorrhizal fungus Paxillus involutus to form mycorrhiza with Populus canescens under sterile conditions. Subsequently, strain Maj and the fungicide Previcur® N were applied to five Populus nigra clones grown outdoors. Various parameters were analyzed, including growth measurements, microsatellite markers, photosynthesis rate, mycorrhizal colonization (ecto- and arbuscular), endophytic fungi colonization, ITS sequencing, biochemical profiles, insect feeding behavior, and volatile compound emissions.
