Efficient transformation of pinaceous gymnosperm cells by Agrobacterium

Creator:: Morris, John W. (John William), 1954-
Abstract:: Agrobacterium tumefaciens and Agrobacteriwn rhizogenes, the causal agents of crown gall disease and hairy root disease, are known for their ability to transfer part of their DNA (the T-DNA) from the bacterial tumor-inducing (Ti) plasmid to the genome of the host plant. Interest has focused on these bacteria because they...

Clonal expansion and seedling recruitment of Oregon grape (Berberis nervosa) in Douglas-fir (Pseudotsuga menziesii) forests: comparisons with salal (Gaultheria shallon)

Creator:: Huffman, David W. (William), 1962- and Tappeiner, John C.
Abstract:: Seedling regeneration and morphology of Oregon grape (Berberis nervosa Pursh) and salal (Gaultheria shallon Pursh) were studied in thinned and unthinned Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the central Coast Range, Oregon. Above- and below-ground growth of both species were significantly and negatively correlated with stand density. Oregon grape...

Density, ages, and growth rates in old-growth and young-growth forests in coastal Oregon

Creator:: Tappeiner, John C., Huffman, David W. (William), 1962-, Marshall, David, Spies, Thomas A., and Bailey, John D.
Abstract:: We studied the ages and diameter growth rates of trees in former Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) old-growth stands on 10 sites and compared them with young-growth stands (50-70 years old, regenerated after timber harvest) in the Coast Range of western Oregon. The diameters and diameter growth rates for the...

Clearcut and shelterwood reproduction methods for regenerating southwest Oregon forests

Creator:: Tesch, S. D., Mann, John William, and Oregon State University. Forest Research Laboratory
Abstract:: Clearcut and shelterwood reproduction methods are both important, silviculturally viable reforestation tools for southwest Oregon. The ecology of local forests lends itself to the successful application of either method, in most cases; thus, choice of method is typically based on land management objectives, which integrate social and resource values, economics,...

Survival and growth of Douglas-fir seed sources in the Hospital Tract rangewide source archive plantation

Creator:: Gamble, William E., Adams, W. T., Tappeiner, J. C. (John C.), and Oregon State University. Forest Research Laboratory
Abstract:: "In 1954, Dr. Helge Irgens-Moller initiated a rangewide collection of seed and seedlings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Nearly 700 trees or stands were sampled in 10 western states, Canada, and Mexico. From 1957 to 1971, 639 of these collections were planted in the Hospital Tract Rangewide Source Archive...
