Abstract

Ectomycorrhizal (ECM) colonization of northern red oak (Quercus rubra L., NRO) seedlings in response to different degrees of overstory and understory removal was investigated in NRO and red pine (Pinus resinosa Ait.) stands in northern Lower Michigan. The experimental design consisted of two stand types (oak and pine), three blocks nested within stand type, four levels of canopy cover (clearcut, 25% first year), 75%, and uncut), and two understory treatments (shrub removal and untreated control). NRO acorns from a common seed source were sown in the spring of 1991 and the emerged seedlings were sampled to quantify their ECM during the first two growing seasons. Photosynthetically acitive radiation (PAR) transmittance was recorded during the second growing season. Soil moisture and temperature were also measured at two- to three-week intervals for the first two years.
