Growth Response of Five Rocky Mountain Conifers to Different Ectomycorrhizal Inocula

Artificial inoculation with the mycorrhizal fungus Pisolithus tinctorius (Pers.) Coker & Couch significantly increased the growth of Engelmann spruce (Picea engelmannii Parry ex. Engelm.) and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) containerized seedling stock. No significant differences in height, diameter, and weight of limber pine (Pinus flexilis James), lodgepole pine (Pinus contorta var. latifolia Engelm.), and ponderosa pine (Pinus ponderosa Dougl. ex Laws.) were noted when artificial and natural inoculation were compared. Root/ shoot ratios were greater with artificial inoculation for lodgepole and ponderosa pines. Pine species readily form P. tinctorius mycorrhizae; Englemann spruce and Douglas-fir do not.
