Relationship of Pratylenchus penetrans (Cobb, 1917) population density and yield of peppermint, Mentha piperita L.

Creator:: Pinkerton, John Nelson
Abstract:: A root-lesion nematode, Pratvlenchus penetrans, was determined to be a major component of peppermint stand decline in Western Oregon. Regression analysis showed that P. penetrans root densities in August were negatively correlated (P=0.01) with yield, while soil densities in August and root and soil densities in April were poorly correlated...

Distribution and Population Dynamics of Plant-Parasitic Nematodes in Oregon Vineyards, and Their Effects on Vine Growth [1994-1995]

Creator:: Ingham, Russell E., Forge, Thomas, Strik, Bernadine C., and Pinkerton, J. N.
Abstract:: Objectives 1. Survey Oregon vineyards for the presence, identity and abundance of plant-parasitic nematodes. 2. Relate the distribution and abundance of potentially pathogenic species to viticultural practices and site characteristics. 3. Evaluate the efficacy of Nemacur for reducing populations of plant-parasitic nematodes. 4. Document seasonal changes in the abundance of...

Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Genetic resistance to eastern filbert blight

Creator:: Coyne, Clarice Jean
Abstract:: Eastern filbert blight, caused by Anisogramma anomala (Peck) E. Muller, is a serious threat to hazelnut (Corylus avellana L.) production. Resistant cultivars offer the best control. Screening systems were needed to reliably identify disease, particularly in immune progeny derived from 'Gasaway'. An indirect enzyme-linked immunosorbant assay (ELISA) was developed using...
