Creator:: Lavender, Denis P. and Oregon State University. Forest Research Laboratory
Abstract:: The effect of lifting Douglas-fir seedlings from the nursery bed and replanting them, either immediately or after storage at 2 C for periods up to six weeks, was investigated through a series of experiments conducted in controlled-environment chambers and under field conditions. Seedlings lifted prior to December, or after buds...

Creator:: Wright, Ernest and Oregon State University. Forest Research Laboratory
Abstract:: Correlation was sought between abundance of mycorrhizae on Douglas-fir seedlings and their survival in field plantations. One possible indication of dormancy desirable for lifting from nursery beds could be the varying seasonal abundance of ectotrophic mycorrhizae on roots of seedlings. No direct correlation between percentage of mycorrhizae and survival in...

Creator:: Kangur, Rudolf and Oregon State University. Forest Research Laboratory
Abstract:: Two intermediate cuttings were made in a Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stand on the Wilark forest management research area in northwestern Oregon. Age of trees in the stand varied from 47 to 62 years at the first cutting. Crawler tractors were used in both extractions. In the first cutting,...

Creator:: Hermann, Richard K. and Oregon State University. Forest Research Laboratory
Abstract:: Planting techniques, size and age of seedlings, and protection against animals were investigated for their influence on survival of ponderosa pine at two sites in southern Oregon. Caging and mulching with paper were the most effective measures for reducing mortality. Preliminary trials prior to large-scale planting were recommended for determining...

Abstract:: This publication is part of a 1-year project funded by the Oregon Department of Agriculture, Alternatives to Field Burning Program. Crop substitution is one strategy for reducing smoke from field burning. The objective of the project was to evaluate the potential for hybrid poplar as an alternative crop for poorly...
