Mine soil properties influencing white pine (Pinus atrobus L.) growth in Southwest Virginia
Thirty-six eight-year-old white pine (Pinus strobus L.) trees were used to identify minesoil, plant moisture, and foliar nutrient properties influencing white pine growth on reclaimed mine sites in southwest Virginia. PRESSAll (SAS Views, 1984) was used to determine relationships between soil …

Biology and natural control of the white pine weevil, Pissodes strobi (Peck), in Virginia
… development and termination of diapause in the white pine weevil were studied by dissecting weevils at various intervals throughout the winter. Old-generation adults brought into the laboratory November produced viable eggs within 5 days. New generation adults brought into the laboratory on …

The response of 12 clones of eastern white pine (Pinus strobus L.) to ozone and nitrogen dioxide
… rootstock and scion from 12 ortets of eastern white pine (Pinus strobus L.) growing at the Radford Army Ammunition Plant (RAAP). The 12 ortets represented 4 symptom severity classes (3 ortets/class) ranging from trees with > 25% of their crowns exhibiting necrotic tipburn (Class I) to those …

Foliar damage and shoot growth changes resulting from exposure of eastern white pine seedlings to nightly acidic mists
Eastern white pine is an important coniferous forest species of the northeastern United States where nightly acidic mists may be a factor in the decline of highland forests. During 3 studies, experimental mists were applied nightly in order to simulate nocturnal misty conditions common in the …

Comparative study of an antioxidant defense mechanism in genotypes of eastern white pine which show differential foliar characteristics
Approximately 10-15% of field-grown eastern white pine (Pinus strobus L.) within a nursery plantation expressed foliar characteristics similar to that induced by oxidant pollution. Sensitive genotypes (based on foliar characteristics), had a 50% reduction in needle growth, severe needle tip burn, …

The etiology of the decline of eastern white pine (Pinus strobus L.) on Virginia landscapes: a survey of stress factors
A decline of eastern white pine, Pinus strobus L., has been observed for over 80 years in the eastern United States. The syndrome has not always been discussed as a decline but reported under a variety of names. Symptoms vary with time required for trees to die, but generally include chlorotic …

Variation in the physiological processes of eastern white pine (Pinus strobus L.) differing in sensitivity to ozone, sulfur dioxide, and nitrogen dioxide
Ten clones of eastern white pine (Pinus strobus L.) representing three different pollutant sensitivity classes (i.e. sensitive, intermediate, and tolerant) were exposed to ozone, sulfur dioxide, and nitrogen dioxide singly, and in. combinations at various concentrations. Visible symptom expression, …

Time series analysis of limber pine (Pinus flexilis) health in the U.S. Rocky Mountains in response to white pine blister rust (Cronartium ribicola) and bark beetles
From 2004-2007, 106 permanent limber pine monitoring plots were established and measured throughout the U.S. Rocky Mountains (MT, WY, CO) to characterize health trends in response to white pine blister rust (WPBR) and bark beetles (including mountain pine beetle, "MPB", and Ips spp., "Ips") over …
