Ryegrass fluorescence expression during three generations of seed increase and its heritability among half-sib families

Creator:: Floyd, Donald J.
Abstract:: Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...

Olives in Oregon: Grower Survey, On-Farm Propagation, and Orchard Establishment in a Non-Traditional Growing Region

Creator:: Barker, Tessa A.
Abstract:: Olive production potential in Oregon was researched in a multi-disciplinary approach, including a grower survey, a propagation greenhouse study, and a field study, from 2018 through 2020. The Oregon Olive Grower Survey was designed to collect information relating to orchard establishment and management practices, knowledge and understanding of these practices,...

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,...

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...

Simple sequence repeat marker development and fingerprinting in Cuphea lanceolata Ait. and C. viscosissima Jacq

Creator:: Karmarkar, Vidyadhar M.
Abstract:: Microsatellites or simple sequence repeats (SSRs) are highthroughput sequence based DNA markers that have been exploited as tools for measuring genetic distance and diversity in evolutionary studies, protection of intellectual property, genetic resource conservation management, cultivar identification and molecular breeding of crop plants. We isolated and sequenced 1095 clones from...

Maturity and stability evaluation of composted yard debris

Creator:: Brewer, Linda J.
Abstract:: Compost maturity is an important determinant of end use for composted municipal yard debris, and generally refers to the effect the compost has on plants. The rate of microbial respiration is an indicator of compost stability. The objectives of this research were to: i) determine whether continuous aeration resulted in...

Bees Associated with Linden (Tilia spp.) Trees and their Susceptibility to Toxic Sugars in Nectar

Creator:: Argoti, Adriana G.
Abstract:: Bees provide critical pollination services to diverse agricultural crops, native plants and trees. Globally, there are reports of bee declines which have been attributed to diseases, exposure to pesticides and changes in land use that are believed to have led to a reduction in foraging resources and nesting habitats for...
