Port-Orford-cedar and Phytophthora lateralis : grafting and heritability of resistance in the host, and variation in the pathogen

Creator:: McWilliams, Michael G.
Abstract:: Port-Orford-cedar (Chamaecyparis lawsoniana) is a forest tree native to a small area of Oregon and California. A root disease caused by Phytophthora lateralis causes widespread mortality of Port-Orford-cedar. This dissertation examines three important elements of the Port-Orford-cedar P. lateralis pathosystem related to breeding for disease resistance: use of resistant rootstocks...

Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...

Genetics of sexuality and population genetics of Phellinus weirii

Creator:: Angwin, Peter A.
Abstract:: Phellinus weirii (Murr.) Gilbertson, cause of laminated root and butt rot, is a heterothallic basidiomycete lacking clamp connections. Two biological species groups of the fungus have been hypothesized, the Douglas-fir and cedar-types, on the basis of physiological, morphological and epidemiological differences. Single-spore and vegetative isolates differ in cultural morphology, nuclear...

Effect of intervention strategies on specific verbal feedback of volunteers and its secondary effect on qualitative motor performance

Creator:: Gately, Jeanne E.
Abstract:: The purpose of this study was twofold. First, to determine if planned interventions could increase untrained undergraduate students' use of positive and specific skill feedback while a teaching fundamental motor skill to children who are disabled. Second, to qualitatively assess the effect of specific verbal feedback on student motor performance....

The infection and colonization of Douglas-fir needles by the Swiss needle cast pathogen, Phaeocryptopus gaeumannii (Rhode) Petrak

Creator:: Capitano, Bryan R.
Abstract:: Phaeocryptopus gaeumannii is a pathogenic fungus on Douglas-fir needles which has become a serious threat to timber production in the last decade along the Oregon coast This research was undertaken to describe the general biology and pathology of F. gaeumannii on Douglas-fir needles and how environmental variables affect fungal development....

Distribution and prediction of Swiss needle cast of Douglas-fir in coastal Oregon

Creator:: Rosso, Pablo H.
Abstract:: This study was directed to improve our understanding of the ecology of Swiss needle cast (SNC) of Douglas-fir, a disease that produces extensive damage to forests and plantation in the coastal region of Oregon and Washington. A disease prediction model for the coastal area of Oregon was built by establishing...

Incompatibility reactions and nuclear condition of three Phellinus species

Creator:: Hennon, Paul E.
Abstract:: Phellinus arctostaphyli (Long) Niemela, P. igniarius (L. ex Fr.) Quel., and P. tremulae (Bond.) Bond. et Boriss., heartrotting hymenomycetes in the family Hymenochaetaceae (Aphyllophorales), all conform to a multi-allelic heterothallic mating system. Both compatible and incompatible reactions result from pairings of homokaryons from the same basidiocarp. Homokaryons isolated from different...
