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:: Hobbs, Stephen D. and Oregon State University. Forest Research Laboratory
Abstract:: Two-year-old Douglas-fir bareroot seedlings were hoe- and auger-planted on droughty south and southwest aspects in southwest Oregon. After 2 years, no differences in height, diameter, or seedling biomass could be detected. Auger-planted seedlings survived significantly better on the southwest aspect.

Abstract:: "An important limitation In the study of tree roots has traditionally been the time necessary to excavate roots without injuring their fine structure. Thus, many root studies have been based on small samples and consequently contain large errors of estimation. This Note describes how large numbers of root systems from...

Creator:: Cleary, Brian D. and Oregon State University. Forest Research Laboratory
Abstract:: "Control of competing vegetation during establishment is one of the key links in the chain of events leading to a new plantation and, ultimately, a productive forest resource. Experience has repeatedly shown that, without adequate site preparation, reforestation efforts almost inevitably will fail. Vegetation control during the establishment period by...

Abstract:: The effects of naturally shaded microsites on survival and height growth of natural and planted seedlings were evaluated after an initial shelterwood harvest in the eastern Siskiyou Mountains of southwestern Oregon. After 2 years, the probabilities of survival for planted Douglas-fir (84 percent) and ponderosa pine (56 percent) were significantly...
