Comparison of the host range and physical properties of Eola rasp leaf, tobacco ringspot and tomato ringspot viruses

Creator:: Liu, Kang-chien
Abstract:: Eola rasp leaf of cherry was first described by Milbrath and Reynolds in Oregon in 1961. Dr. Cadman of the Scottish Horticultural Research Institute suggested that this disease was incited by a strain of tomato ringspot virus (TomRSV), but since then controversial results with some isolates of EoIa rasp leaf...

Dry coniferous forests in the Western Oregon Cascades

Creator:: Means, Joseph E.
Abstract:: Pseudotsuga menziesii dominates the forests of the Pacific Northwest. But though it is dominat, Tsuaa heteroohylla or Abies amabilis is usually climax. Many researchers have studied Pseudotsuga on the widespread mesic sites where it is seral, but few have examined the relatively rare ecosystems in which Pseudotsuga or its associate...

Host range, serological and electron microscope studies of phages of Agrobacterium tumefaciens (Smith and Townsend) Conn

Creator:: Buangsuwon, Pairoj
Abstract:: Phages of crown gall bacteria were among the first to be isolated and certain properties of these phages have been studied by a number of investigators. However, several important characteristics have not been studied in detail. The present investigation was made in order to determine the major sources of phages...

Microsite selection of resident and invading plant species following logging and slash burning on Douglas fir clear-cuts in the Oregon Coast Range

Creator:: Cox, Stephen William
Abstract:: In 1967 an investigation seeking to understand the disturbance effects produced by broadcast slash burning was conducted on Douglas fir clear-cuts in the Harlan area of the Siuslaw National Forest. Specifically, this study was concerned with the effects disturbance has on the growth (spatial) patterns and the replacement (time) patterns...

The ecology and reproduction of Sophora leachiana Peck (Fabaceae)

Creator:: Crowder, Cheryl Alison
Abstract:: The goal of the study was to collect data on the ecology and reproduction of Sophora leachiana in order to help explain the rarity and restricted range of this species. There are 13 known populations of S. leachiana, occurring in a 29 by 6.4 km area in the Siskiyou Mountains...

The influence of tree cover and shade pattern upon the distribution of understory plants in ponderosa pine stands of central Oregon

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Seven sites of uniform topography and soil were selected within a self perpetuating ponderosa pine forest found on the eastern flank of the central Oregon Cascades. These plots were located along a vegetational gradient caused mainly by an orographic rain shadow. Data gathered included density, frequency, and cover for all...
