Abstract

Jack pine (Pinusbanksiana Lamb.) seedlings were grown for 20 weeks in a peat–vermiculite medium inoculated with solid carrier mycelial inoculum. The low fertilizer levels used resulted in seedling sizes below standard for outplanting but permitted mycorrhizal development by 9 of the 12 fungi tested. Greater than 90% of the short roots were infected when seedlings were inoculated with Thelephoraterrestris Ehrhart ex Fr., Laccariaproximo Boudier, Hebeloma sp., or E strain. About half the short roots were infected when Cenococcumgeophilum Fr., Pisolithustinctorius (Pers.) Coker & Couch, and Astraeushygrometricus (Pers.) Morgan were used. Thirty-two and 17% of the short roots were infected by Lactariusparadoxus Beardslee & Burlingham and Sphaerosporellabrunnea (Alb. & Schw. ex Fr.) Svrcek & Kubicka, respectively. Inoculation with Amphinemabyssoides (Fr.) J. Erikss., Hydnumimbricatum L. ex Fr., and Tricholomaflavovirens (Pers. ex Fr.) Lundell resulted in no infection.
