Transplant shock in stored and unstored 2+0 Douglas-fir seedlings : effect of initial root volume and soil water content

Creator:: Haase, Diane L.
Abstract:: Transplant shock was induced by applying a range of soil water contents to unstored and cold-stored two-yearold (2+0) bareroot Douglas-fir seedlings graded by root volume. Moisture stress had the greatest influence on morphological characteristics commonly associated with transplant shock. Terminal growth, lateral growth, stem diameter growth, and needle length increased...

Simulating Effects of Genetic Tree Improvement on Growth and Yield of Coastal Douglas-fir

Creator:: Joo, Sukhyun
Abstract:: Estimating volume gains in genetically improved stands at rotation age is challenging because first-generation progeny tests in Douglas-fir were typically established to measure the relative growth performance of individual trees from open-pollinated parent trees. The overall goal of this dissertation research was to improve growth simulation of genetically improved Douglas-fir...

The impact of microclimate variation on budburst phenology within a mature Douglas-fir tree (Pseudostuga menziesii)

Creator:: Miller, Rebecca A.
Abstract:: Budburst, the initiation of annual growth in plants, is sensitive to climate variation and is therefore used to monitor physiological responses to climate change. Budburst timing can vary between regions of an individual tree, but this phenomenon it is unaccounted for in current monitoring efforts and may contribute to the...
