Loblolly pine (Pinus taeda) seedlings from three full-sib families were exposed to 0, 50, 100 or 150 ppb ozone (O(3)) (5 h/d, 5 d/week for 6 or 12 weeks). Soil water potential was maintained near pot… Expand
Incidence of Phytophthora Root Rot of Fraser Fir in North Carolina and Sensitivity of Isolates of Phytophthora cinnamomi to Metalaxyl.
A survey of Fraser fir Christmas trees in North Carolina for incidence of Phytophthora root rot was conducted during 1997 and 1998. Field sites (7- to 13-year-old trees) and nursery transplant beds… Expand
Phylogenetic and phenotypic characterization of Fomes fasciatus and Fomes fomentarius in the United States
The wood-decay fungi Fomes fasciatus and F. fomentarius share many morphological characters that historically have made species delimitation challenging. We examined morphological, molecular and… Expand
Formation of ectomycorrhizae on Pinustaeda seedlings exposed to simulated acidic rain
Effects of simulated acidic rain on formation of ectomycorrhizae were studied with Pinustaeda seedlings grown in plastic trays in a greenhouse. Trays of ectomycorrhizal seedlings were exposed 37… Expand
Effect of fertilization on production of epigeous basidiocarps by mycorrhizal fungi in loblolly pine plantations
Basidiocarps of 39 epigeous species of proven or potential mycorrhizal fungi were found in three fertilized Pinus taeda plantation s during 1972 and 1973. The largest numbers of basidiocarps on all...
Temporal and Spatial Epidemiology of Phytophthora Root Rot in Fraser Fir Plantations.
In 1999, 19 plots of Fraser fir (Abies fraseri) with a disease focus were established in commercial plantings grown for Christmas tree production in the mountains of five western North Caro-lina… Expand
SUSCEPTIBILITY OF CULTIVARS AND HYBRIDS OF KOUSA DOGWOOD TO DOGWOOD ANTHRACNOSE AND POWDERY MILDEW
Twenty taxa of dogwood including cultivars of kousa dogwood (Cornus kousa) and cultivars of hybrids be- tween flowering (Cornus florida) and kousa dogwoods were evaluated for susceptibility to… Expand
