The identity and host relations of the late-breaking virus

Creator:: Raymer, William Bruce
Resource Type:: Dissertation

Resource Type:: Dissertation
Full Text:: sprout, obtained infections of healthy plants using the aphids 1\rZus persicae, 1ï. solani (Kalt

Seedborne Phytophthora infestans : effect of pathogen clonal lineage and potato cultivar on seed transmission of late blight and plant growth responses

Creator:: Partipilo, Heather M.
Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

The relation of chlorogenic acid and total free phenols in potato plants to resistance to infection by Verticillium albo-atrum

Creator:: Patil, Suresh S.
Resource Type:: Dissertation
Full Text:: vascular systems of root tips and sprout tips of young potato plants. It has been reported by Tolmsoff

Monitoring potato leafroll virus movement in differentially aged potato (Solanum tubersom L.) plants with an immunosorbent direct tissue blotting assay

Creator:: Whitworth, Jonathan L.
Abstract:: Potato leafroll virus (PLRV) causes yield and quality losses in potato. PLRV is identified by plant symptoms and serological tests such as an enzyme-linked immunosorbent assay (ELISA). A similar serological test, direct tissue blotting assay (DTBA), was used to detect and monitor PLRV movement in field-inoculated Russet Burbank plants and...
Resource Type:: Dissertation
Full Text:: (A) healthy eye; (B) PLRV-infected sprout on a seed piece. Each blot is a core of an eye cut and

Soil water pressure and Verticillium dahliae interactions on potato

Creator:: Gaudreault, Suzanne M.
Abstract:: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10...

Water deficit stress effects on bacterial ring rot of potato caused by Clavibacter michiganensis subsp. sepedonicus

Creator:: Crabtree, Kristine L.
Abstract:: Population size of Clavibacter michiganensis subsp. sepedonicus in potato cv Russet Burbank and plant response as affected by drought were assessed in a greenhouse experiment. Water deficit stress and no stress treatments, and inoculum densities of 0 or 2 X 10⁷ cfu C. m. sepedonicus/seed piece were arranged factorially. Stem...

Rhizoctonia of the potato

Creator:: Corsaut, Jesse Harrison
Resource Type:: Masters Thesis

Optimizing virus detection in potato breeding populations

Creator:: Hane, Dan C.
Abstract:: Virus contamination in a potato breeding program can seriously disrupt the variety development process. Experiments were conducted from 1989 through 1993 to: evaluate the extent to which Potato Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding program, determine viral spread within hills and within individual tubers,...
