| 要旨本文 | This study aims to clarify the potential role of mycorrhizal fungal species on the growth of Dahurian larch, which forms the northernmost treeline of the Eurasian arctic. We conducted inoculation experiments to determine how the growth of larch seedlings differs depending on the mycorrhizal fungal species identified in the soils of the tundra zone. We cultured strains of mycorrhizal species specific to larch (genera Suillus and Rhizopogon) and an early successional species (Thelephora terrestris). Larch seedlings inoculated with T. terrestris grew more than twice as fast as uninoculated seedlings, measured by dry weight. Suillus species increased seedling growth to various degrees. In contrast, an arctic species of Rhizopogon laricinus showed limited inoculation rates under the current growth conditions. |
