Abstract
In this study, the mobilization and further translocation of phosphorus from conidia of saprotrophic fungus Trichoderma virens into Pinus sylvestris seedlings by nondestructive measuring of (32)P was assessed. The radioactive phosphorus flux from the conidia to the Scots pine seedlings forming mycorrhiza with Laccaria laccata and Suillus bovinus amounted up to 27.82% and 7.42%, respectively, on the 28th day of the experiment, while at the same time in nonmycorrhizal pine seedlings, the detected radioactivity reached only 0.56%. Our studies revealed that both ectomycorrhizal fungi: L. laccata and S. bovinus, mobilized the phosphorus from radioactive conidia of T. virens. On this basis, we conclude that activities of the mycosymbionts may facilitate absorption and further translocation of phosphorus from organic matter into the host plants.
