Epicuticular Wax and White Pine Blister Rust Resistance in Resistant and Susceptible Selections of Eastern White Pine (Pinus strobus).
ABSTRACT Epicuticular wax on needles was evaluated for its influence on Cronartium ribicola infection of resistant and susceptible selections of Pinus strobus. Environmental scanning electron microscopy comparisons revealed that needles from a resistant selection of eastern white pine, P327, had a significantly higher percentage of stomata that were occluded with wax, fewer basidiospores germin...
متن کاملResponse of Planted Eastern White Pine (Pinus strobus L.) to Mechanical Release, Competition, and Drought in the Southern Appalachians
Conversion of low-qual i ty , natural mixedpinelhardwood ecosystems, containing a mountain laurel (Kalmia latifolia L.) dominated understory, to more productive eastern white pine (Pinus strobus L.)l mixed-hardwood systems is a common prescript ion on relat ively xeric southern Appalachian forest s i tes . We examined the ef fects of mechanical release, interspeci f ic competi t ion, and annual...

Chainsaw fe l l ing , burning, and p lant ing of eastern whi te pine (Pinus s t robus L.) have been prescribed on degradedpinelhardwoodstands in the Southern Appalachians to improve overstory composi t ion and product iv i ty . The desired future condi t ion the overstory is a product ive pinelhardwood mixture, wi th white pine, which is resistant to southern pine beetle (Dendroctonus frontalis...
متن کاملSingle-Locus versus Multilocus Patterns of Local Adaptation to Climate in Eastern White Pine (Pinus strobus, Pinaceae)
Natural plant populations are often adapted to their local climate and environmental conditions, and populations of forest trees offer some of the best examples of this pattern. However, little empirical work has focused on the relative contribution of single-locus versus multilocus effects to the genetic architecture of local adaptation in plants/forest trees. Here, we employ eastern white pin...
متن کاملGenetic diversity and population structure of disjunct Newfoundland and central Ontario populations of eastern white pine (Pinus strobus)
The dramatic decline of eastern white pine (Pinus strobus L.) populations in Newfoundland over the past 100 years presents an opportunity to determine and monitor population bottleneck effects on genetic diversity in trees. To provide benchmarks and indicators for monitoring genetic changes due to recent and future bottleneck events and to assist development of conservation strategies, we asses...
