Sintesi micorrizica tra Pinus strobus e Tuber maculatum. I. Micorrize e sviluppo dei semenzali nel secondo anno

The authors obtained mycorrhizal synthesis of Tuber maculatum with Pinus Strobus seedlings. In addition to an abundant production of the distinctive ectomycorrhizae peculiar to this fungus, young ascocarps of Tuber maculatum formed in inoculated pots before the third growing season. The experiment was carried out in two substrata: 1) calcareous sail + peat, 2) calcareous soil + peat + vermiculite. Mycorrhizae and ascocarps were formed in both substrata, though in the vermiculite substratum inoculated with Tuber maculatum growth was significantly higher than in the absence of either vermiculite or inoculum. The inoculation technique will be used on a larger scale with Pinus Strobus and Tuber maculatum in tests of adaptation to different soils.
