Early realized genetic gains for coastal Douglas-fir in the Northern Oregon Cascades. Western-Journal-of-Applied-Forestry 19(3): 195-201. Keywords: genetic tree improvement growth 251 Abstract: Block-plot realized genetic gain trials were established for coastal Douglas-fir (Pseudotsuga menziesii var. menziesii) at five sites in the northern Oregon Cascades. The longterm objectives of these trials are to explore the growth trajectories and productivity of genetically improved stands and their relationship to predicted genetic gains based on performance in progeny tests. Measurements 5 years after planting provide an opportunity for an early assessment of realized genetic gains as compared to predicted gains and provide data for determining the number of replicates needed to detect statistically significant differences between improved and unimproved populations using large block plots. Results indicate that progress from selection and breeding of Douglas-fir is readily achievable, and realized genetic gains 5 years after planting are similar to those predicted based on results from progeny tests. Realized genetic gains were about 6% for height, 8% for diameter, and 28% for stem volume, compared to predicted genetic gains of about 8% for height, 7% for diameter, and 25% for stem volume. Large numbers of replicates (30-50) are required to detect statistically significant differences in height and diameter between improved and unimproved populations given genetic gains expected in a typical tree improvement program. 573. St-Clair, J.B. and R.A. Sniezko. 1999. Genetic variation in response to shade in coastal Douglasfir. Canadian-Journal-of-Forest-Research 29(11): 1751-1763. Keywords: genetic tree improvement growth tree morphology carbon allocation tree phenology Abstract: Tree improvement programmes have generally relied on testing families in open light environments. With increased interest in multiaged silvicultural systems, some people have questioned whether families selected in the open are appropriate for planting in the shade. Douglas-fir (Pseudotsuga menziesii var. menziesii) families from two climatically distinct seed sources in the Coast Range (NW Oregon) and Siskiyou Mountains (SW Oregon) were grown for 2 years under four levels of shade. The response to shade differed for several traits between the two populations and among families within populations. The magnitude of variation associated with the interaction, however, was small compared with the overall effects of genetic selection or of shade. Families selected based on performance in an open light environment resulted in nearly the same response to selection when grown under shade as families selected based on performance in the shade. It is concluded that seedlings from families selected in an open light environment are appropriate for use in the low-light environments of alternative silvicultural systems and that use of such genetically selected stock may compensate for the less favourable growing conditions. Genetic selection may contribute importantly to meeting multiple objectives, including the production of significant amounts of wood as well as the efficient and timely creation of large stand structures needed for other forest values.

Canadian-Journal-of-Forest- Research 20(3): 343-349. Keywords: fertilization thinning growth Abstract: Basal area and volume growth response of unthinned and thinned Douglas fir (Pseudotsuga menziesii) stands to single and multiple applications of N fertilizer (as urea) were estimated for eight 2-yr periods in second-growth stands in Washington and Oregon. Response estimates, as differences between growth rates on fertilized and control plots after adjusting for initial volume (or basal area), and trends, were analysed on a regional scale. Average responses to the initial fertilization and to both the second and third fertilizer applications, 8 and 12 yr later, were statistically significant (P
