The effect of forest fertilization on the ectomycorrhizae of western hemlock (tsuga heterophylla)
Granular urea (46% N) was applied at rates of 224 Kg N/ha and448 Kg N/ha to 4x4 m plots within a 20 yr. old stand composed almost exclusively of western hemlock [Tsuga heterophylla (Rafn.)Sarg.], located in the Mount Seymour Demonstration Forest, North Vancouver, British Columbia. Changes in the …

The effect of ectomycorrhizae on the uptake of lead by Pinus sylvestris L. seedlings
… were combined to determine the effect of ectomycorrhizae on the uptake of lead by Pinus sylvestris L. seedlings. By culturing the ectomycorrhizal fungus, Pisolithus tinctorius (Pers.) Coker and Couch, in liquid Hagem's medium with different concentrations of lead (0, 50, 250 and 500 ng/g …

The incidence of ectomycorrhizae by Pisolithus tinctorius on Quercus rubra seedlings fertilized with sodium nitrate and ammonium chloride
… (480) were ectomycorrhizal with P. tinctorius. Ectomycorrhizae other than those characteristically produced by P. tinctorius were not observed and all non-inoculated seedlings (480) were free of ectomycorrhizae. Ectomycorrhiza formation was enhanced with late nitrogen applications; however, …

Pisolithus Tinctorius Mycobiont Inoculations as a Factor in Performance of Containerized and Bare-Root Shortleaf Pine Seedlings on Lignite Minesoils in Panola County, Texas
… of the fungal symbiont Pisolithus tinctorius on ectomycorrhizae development of short leaf pine (Pinus echinata) seedlings grown in styroblock containers were tested in the greenhouse. These preliminary tests showed that both spores and mycelia will produce satisfactory ectomycorrhizae …

The systematics and ecology of Boletes with special reference to the Genus Suillus and its ectomycorrhizal relationships in Nepal
… completely. Cultures of eight and synthesized ectomycorrhizae of six of the Suillus species are described. Synoptic keys to the basidiocarps and to the cultures are presented. Numerical taxonomic analyses of the cultures generated clusters which paralleled the species concepts developed using …

The effects of age and size of canopy gaps on the mycorrhizae of yellow birch (Betula alleghaniensis Britton) and sugar maple (Acer sacchrum Marsh.) from deciduous forests of the Québec city region
… sized and different aged canopy gaps on the ectomycorrhizae of yellow birch and vesicular-arbuscular mycorrhizae of sugar maples collected from two deciduous forests in central Quebec were examined. The colonization of maple roots by arbuscules, vesicles, and coils were quantified. …

Trace metal effects on ectomycorrhizal growth, diversity, and colonization of host seedlings
… is discussed. The third experiment surveyed ectomycorrhizae on a mine reclamation project in Wise County, Virginia. Pinus strobus trees planted 1, 8, 13, and 25 years prior to the experiment were sampled. Colonization was lower than in well developed soils, but occurred on all seedlings. …

Influence of Mycorrhizal Inoculation Treatments on Native Tree and Shrub Survival in a Floodplain, Flathead Indian Reservation
Mycorrhizal inoculum treatments of two marketed products, Mycopak and Biogrow, were tested against forest soil, and a control treatment on biomass and survival of Populus tremuloides, Salix bebbiana, Populus trichocarpa, and Cornus stolonifera during the summer of 2003 and 2004. Because these …

The Inhibitory Effect of Rhododendron maximum L. (Ericaceae) Thickets on Mycorrhizal Colonization of Canopy Tree Seedlings
Thickets of Rhododendron maximum (Rm) in the southern Appalachians impose severe limitations on the regeneration of hardwood and coniferous seedlings. Interactions between Rm thickets and ectomycorrhizal colonization were examined to explain seedling inhibition. Experimental blocks were established …

The Fungal Connection: Characterizing the Ectomycorrhizal Community and Belowground Response to Restoration Treatments in Northern Mississippi.
Ectomycorrhizal (ECM) fungi are symbionts on the roots of woody plant species throughout the world. These fungi provide plants with nutrients and are important drivers of ecosystem processes. ECM fungi vary in their effect on host plants and host-specificity, making them important considerations in …
