Trichoderma spp. : distribution in stumps infested with Phellinus weirii and growth and antagonism in vitro

Creator:: Goldfarb, Barry
Abstract:: To determine which isolates will most rapidly replace Phellinus weirii in stumps and roots, Trichoderma spp. were isolated from P. weirii-infested stumps and roots, identified, and examined for growth rates and lethal effects on P. weirii in vitro. Phellinus weirii-infested Douglas-fir stumps and stump roots were sampled for microorganisms by...

Susceptibility of coast redwood seedlings to Phytophthora ramorum

Creator:: Lucas, Sunny L.
Abstract:: Coast redwood (Sequoia sempervirens) (D. Don) Endl. is a host for Phytophthora ramorum but it was unclear if the pathogen represents a significant disease risk to this tree species. In this study the susceptibility of coast redwood seedlings and the likelihood of sporulation on redwood were examined. Two methods were...

Succession and certain adaptive features of plants native to the sand dunes of the Oregon coast

Creator:: Kumler, Marion Lawrence, 1941-
Abstract:: The vegetation of the Oregon coast is characterized by a variety of stages of plant succession which are repeated widely throughout the sand dune area. During the years from 1960 to 1963 the gradation of upland sand dune succession was studied on 48 plots within a 150 mile section of...

Abstract:: Forest health issues are on the rise in the United States, resulting from introduction of alien pests and diseases, coupled with abiotic stresses related to climate change. Increasingly, forest scientists are finding genetic/genomic resources valuable in addressing forest health issues. For a set of ten ecologically and economically important native...

Description and classification of the forests of the upper Illinois River drainage of Southwestern Oregon

Creator:: Atzet, Thomas
Abstract:: The purpose of this study was to develope a plant community classification within the Siskiyou mountains, a small range within the Klamath geological province well known for its geologic and floristic diversity. Forest land managers have expressed the need for identification of basic Land classes that will aid in the...

Contributions to the plant ecology of the Oregon coastal sand dunes

Creator:: Wiedemann, Alfred M.
Abstract:: Sand dunes are found along the coasts of most of the large land masses of the world. Because of their proximity to man and his activities, the maritime sand dunes of Europe, particularly Germany, France, Holland and Scandinavia, have the longest history of stabilization activities and botanical investigation. There are...

Contracting nucleolar vacuoles in somatic tobacco cells growing in microcultures

Creator:: Johnson, John Morris
Abstract:: Contracting nucleolar vacuoles are a general and consistent feature of somatic tobacco cells growing in microcultures. Nucleolar vacuoles were studied in cells from callus tissues of two single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana tabacum X N. glutinosa). Vacuoles periodically contracted either completely or incompletely, apparently releasing a...

An analysis of montane forest vegetation on the east flank of the central Oregon Cascades

Creator:: West, Neil E.
Abstract:: Montane forest vegetation as it occurs on the east flank of the central Oregon Cascades has provided excellent conditions for a "natural experiment" in the use of various methodologies in studying vegetational distribution. This "experiment" has reflected on some theory and practice for the discipline of plant synecology. Detailed descriptions,...
