A large insert genomic library from eastern white pine (Pinus strobus) was probed for the microsatellite motifs (AC)n and (AG)n, all 10 trinucleotide motifs, and 22 of the 33 possible tetranucleotide motifs. For comparison with a species from a different subgenus, a loblolly pine (Pinus taeda) genomic library was also probed with the same set of di- and tri-nucleotide repeats and 11 of the tetr...

BACKGROUND Tests were conducted on two insecticides (carbaryl and bifenthrin) for excluding subcortical beetles (Coleoptera: Curculionidae and Cerambycidae) from loblolly pine trees (Pinus taeda L.). Two trap designs (single- and double-pane windows) and two trapping heights (1.5 and 4 m) were also evaluated for maximizing beetle catches. RESULTS In July 2009, 15 loblolly pine trees were doub...

This review compares fall acclimation patterns and lift/store practices for Pseudotsuga menziesii var. menziesii, Picea glauca (Moench) Voss x P. engelmannii Parry ex engelm and Pinus taeda L. seedlings. Spruce seedlings achieve budset and an endodormant state in late summer, coastal Douglas-fir in early fall, while loblolly pine achieves a less endodormant state with a limited amount of mitoti...

Few studies have examined the combined effects of nutrition and water exclusion on the canopy physiology of mature loblolly pine (Pinus taeda L.). Understanding the impacts of forest management on plantation productivity requires extensive research on the relationship between silvicultural treatments and environmental constraints to growth. We studied the physiological responses of 18-year-old ...

Surrogate pollen induction (SPI) was evaluated on loblolly pine (Pinus taeda L.) donor scions from 5-year-old progeny that were grafted by topworking into the lower crowns of 16-year-old loblolly pine receptor clones in a seed orchard. On each of 25 study trees, one of three pollen induction treatments (wire girdle, saw girdle or control) was applied to 10 receptor branches below the graft loca...

Multiple TREGRO simulations were conducted with meteorological data files containing different growing season peak ozone (O(3)) episodes at O(3) exposures of 1.0 and 2.0 x ambient O(3) to assess the relationship between O(3) response and the phenology of mature yellow poplar (Liriodendron tulipifera L.) and loblolly pine (Pinus taeda L.) trees. Regardless of O(3) exposure and peak O(3) episode ...
