Effect of Plant Growth Regulator and Irrigation on Physiological and Harvest Maturity of Red Clover in Relation to Seed Quality

Creator:: Angsumalee, Duangporn
Abstract:: Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...

Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Small broomrape (Orobanche minor) biology and management in red clover (Trifolium pratense) seed production

Creator:: Lins, Ryan D.
Abstract:: Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...

The effect of winter grazing on production and dynamics of a Lolium perenne (L.)-Trifolium repens (L.) pasture

Creator:: Jaindl, Raymond G.
Abstract:: Perennial ryegrass (Lolium perenne) - white clover (Trifolium repens) hill-land pastures were grazed at different times in the winter to study the effect of time of winter grazing on plant response and forage production. The same pastures were grazed by sheep once in early December, January, February, March, or April...

Seed quality and plant establishment studies of seashore paspalum (Paspalum vaginatum Sw.)

Creator:: Baker, Stanley D.
Abstract:: Seashore paspalum (Paspalum vaginatum Sw.) is an important warm-season perennial turfgrass, known for its tolerance to salinity. Turfgrass is used for homes, municipalities, sod farms, resorts, and sports fields. Seashore paspalum has historically been planted in sub-tropical and tropical climates because of its heat tolerance. Seashore paspalum could become an...

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...

Genetic variation and phenotypic stability among three elevational sources of coastal Douglas-fir from southwest Oregon

Creator:: Mangold, Robert
Abstract:: This study had three objectives: (1) to determine the degree to which within-source genetic variation and genetic correlations differ among elevational sources of Douglas-fir [Pseudotsuga menziesii (Mirb). Franco var. menziesii]; (2) to ascertain the degree to which phenotypic stability differs among and within elevational sources; and (3) to compare the...
