摘要: summary Concentrations of indole-3-acetie acid (IAA) in lateral roots, fungal biomasa (ergosterol) roots and extrametrical mycelium, carbohydrates minerals shoots were measured mycorrhizal non-mycorrhizal Pinus sylvestris L. seedlings supplied with different amounts N P. IAA concentrations the same or lower than those control seedlings. The root tips Laccaria bicolor inoculated 40% roots. color-inoculated positively related to X supply. A rise supply reduced development extramatrical mycelium biomass Hebeloma crustuliniforme-inoculated High starch, Ca Mg but increased glucose fructose. P had no effect on growth IAA. Fungal was negatively correlated levels soluble shoots, shoot N, K, relative rate shoot: ratio Starch, growth. No support found for hypothesis that is important regulating colonization.
