General outcomes of this study show that early growth of planted red alder is often slowed in the presence of neighboring vegetation, and overwhelmingly by salmonberry, a common associate in disturbed Oregon Coast Range habitats. Additionally, young red alder plantations located in
riparian areas may be highly susceptible to frost...
Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and bigleaf maple) in mixed-species old-growth forests of the Oregon Coast Range and to determine whether and how soils differ among the...
Two winter wheat (Triticum aestivum L. em Thell) and two
winter barley (Hordeum vulgare L. em Thell) cultivars were grown
with and without straw mulch utilizing six different planting dates.
Soil temperature was recorded continuously at seeding depth from
planting date through March of the crop year. A series of...

The growth of western hemlock during the first four
years of seedling establishment was examined in a competitive
environment in which seedlings were exposed to various types
of animal damage and salmonberry and/or alder competition.
The study utilized an existing Nelder/replacement series
experiment which focused on the competitive effects among...
This thesis concerns the alteration of the course of selective
protein synthesis and morphogenesis in plants treated with growth
regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings
(Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused
inhibition of epicotyl and primary root elongation and proliferation of
massed lateral...
