An evaluation of creeping habit in various progenies of red fescue (Festuca rubra L.)

Creator:: Kim, Dal Ung
Abstract:: Thirty-three genotypes of red fescue were selected on the basis of diverse origin, anthesis date, and type of spreading from a space-planted introduction nursery. Open-pollinated, single-cross, and top-cross progeny nurseries were established into a randomized block with four replications, 20, 9, 8 entries, respectively, with nine plants per entry on...

In vitro and in vivo evaluations of chemically treated ryegrass straw

Creator:: Anderson, Daniel Craig
Abstract:: Seven in vitro trials were conducted to compare the effects of soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH), potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM) was the criterion used to measure treatment response. A 3 x 3...

Evaluation of three methods of selection in relation to yield and yield stability in winter wheat (Triticum aestivum Vill., Host)

Creator:: Charoenwatana, Terd, 1937-
Abstract:: The effectiveness of early generation selection for yield and yield stability and the possible identification of superior parental combinations were studied in winter wheat populations representing different levels of genetic diversity. Experimental material for evaluating yield stability consisted of nine bulk and seven modified bulk populations derived from nine parental...

The examination of seed yield potential in certain genotypes of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: Bresciani, Juan Carlos
Abstract:: In the last 30 years, birdsfoot trefoil (Lotus corniculatus L. ) has been recognized as a great potential source of forage. Since the 1930's, many studies have been reported in relation to birdsfoot trefoil characteristics, including some directly related with the association between seed yield and its components. The purpose...

Effect of chlorpropham on vegetative and reproductive development in chewings fescue (Festuca rubra L. subsp. commutata Gaud.)

Creator:: Akobundu, I. O.
Abstract:: Experiments were conducted under field and greenhouse conditions to investigate the effects of chlorpropham (isopropyl mchlorocarbanilate) on vegetative and reproductive development in Chewings fescue (Festuca rubra L. subsp. commutata Gaud.) and to determine the time of induction and initiation under natural conditions. Chewings fescue was found to be very susceptible...

Nitrite dissimilation by microorganisms incapable of efficient nitrate utilization : nutritional and ecological considerations

Creator:: Vangnai, Somsak
Resource Type:: Dissertation

An examination of seedling vigor and the effects of genetic diversity on response to heterosis in tall fescue (Festuca arundinacea Schreb.)

Creator:: Moutray, Jim B., 1939-
Abstract:: Response to heterosis for plant height, anthesis date, panicle number, seed yield, and fall vigor rating was determined in a tall. fescue group selected for diverse morphology, origin, and anthesis date. Parents, single-cross progeny (SX), and first generation selfed progeny (S₁) were included in the study. Each experimental plot consisted...

Relationships of clay mineralogy to landscape stability in Western Oregon

Creator:: Taskey, Ronald D. (Ronald David), 1944-
Abstract:: Soil erosion by mass wasting is the major problem on forest lands of the Pacific Northwest, The clay fractions of soils from a large number of sites in Oregon's Western Cascades were characterized in order to determine the relationships of various clay materials to mass movements. Each site was either...

Meiotic irregularities in selected parents and their hybrids in tall fescue (Festuca aruninacea, Schreb.)

Creator:: Woodward, W. T. W. (William T. W.)
Resource Type:: Dissertation

Alfalfa cutting management in the Columbia Basin

Creator:: Suttner, Donald Lee
Abstract:: Field studies to determine appropriate cutting management regimes consistent with yield, quality, and persistence of stand were conducted on several alfalfa varieties in the Columbia Basin region of Oregon. Two groups of treatments, including consecutive cuts at the same stage of maturity and cuts made at varying maturities, were imposed...
