Performance of Outplanted Western Hemlock (Tsuga heterophylla (Raf.) Sarg.) Seedlings Inoculated With Cenococcum geophilum

In the first of two experiments, container-grown seedlings of western hemlock (Tsuga heterophylla (Raf.) Sarg.) inoculated with Cenococcum geophilum Fr. had significantly (P = 0.05) better top growth 2 years after outplanting than did noninoculated controls. Seedling survival was unaffected by mycorrhizal inoculation. In the second experiment, western hemlock seedlings inoculated with Cenococcum-bearing rotten wood and noninoculated western hemlock seedlings planted in either rotten wood or mineral soil on a clearcut in western Oregon survived and grew equally well during the first two growing seasons. Survival was not affected by mycorrhizal inoculation but significantly (P = 0.05) fewer seedlings survived in rotten wood than in mineral soil because of the higher second-season mortality in rotten wood.
