Sorensen's 24 research works with citations and reads, including: Effects of seed source origin on bark thickness of Douglas-fir (Pseudotsuga menziesii) growing in southwestern.   Abstract: Forest genetics (FG) research in the United States began more than years ago with racial (seed source) trials of ponderosa pine (Pinus ponderosa Douglas ex C. Lawson) and Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and over the ensuing four decades gradually emerged as a distinct and important discipline of study within the forestry research by:   Douglas-fir range-wide variation results from the IUFRO data base.

Until recently, phenology, the study of periodic phenomena in plants and animals, has been limited in practice largely to observation of visible by:

The leaf life-span of trees appears to be inversely related to solar radiation. For instance, in three Japanese conifers, maximum needle life-span of year-old individuals was 15–40% less when grown under full sunlight rather than beneath a hardwood forest canopy ().Life-span of foliage in sunny parts of the crown, especially the upper part, is shorter than that of shaded crown positions Cited by: How to Copy and Paste from Microsoft Word to Email - Oak Lawn pdf Кб.
