The effect of harvest date and pre-storage drying methods on capsule thebaine yield, seed oil yield, and seed germination of two accessions of Papaver bracteatum Lindl.

Creator:: Seddigh, Majid
Abstract:: A field study was conducted in 1978 and 1979 at the Hyslop Crop Science Field Laboratory near Corvallis, Oregon, to determine the optimum capsule harvest date of Papaver bracteatum Lind. for thebaine yield and oil yield, while maintaining an acceptable percentage of seed germination. Accessions PI 383309 and PI 381607...

Apoplastic distribution of atrazine and glyphosate in intact sunflower leaves

Creator:: Jachetta, John Joseph
Abstract:: Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)- 6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)- glycine], the naturally occurring apoplastic leaf solutes, and the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate) were compared. Aliquots of sap were expressed from intact sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4 bars. Three distinct fractions were detected...

Experimental studies on species relationships in T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: A study of populations characteristics of T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides was completed using numerical analysis. A sample of 74 accessions of ssp. carthlicum and 20 of ssp. carthlicoides were scored for 46 characters. It was established that three morphological distinguishable groups of ssp. carthlicum can...

Pollination biology and pollinator alternatives in mermaid meadowfoam (Limnanthes alba Hartw. ex Benth.)

Creator:: Jahns, Thomas R.
Abstract:: Meadowfoam (cultivar Mermaid) is an entomophilous winter annual oilseed crop that has historically produced an average of only two of five seeds per flower. Reference to inadequate meadowfoam pollination exists in the literature, but quantitative evidence is lacking. Studies were undertaken to: 1) quantify meadowfoam pollination requirements and 2) evaluate...

Enhancement of 'Scio' barley seed protein by late foliar applications of urea-ammonium nitrate

Creator:: Turley, Robert H.
Abstract:: Foliar applications of urea-ammonium nitrate (UAN) around anthesis increased seed protein content by about 40% in 1983 and 1984 in 'Scio' barley (Hordeum vulgare L.). In exploring the mode and the mechanism of this increase, agronomic and physiological studies were conducted. The late N applications did not affect yield or...

The effect of precipitation variation on soil moisture, soil nitrogen, nitrogen response and winter wheat yields in eastern Oregon

Creator:: Glenn, D. M. (David Michael)
Abstract:: The semi-arid regions of the Pacific Northwest are characterized by a high degree of annual temperature and precipitation variation. As a result of this climatic variation, dryland nitrogen fertilizer trials on fallow- ,wheat rotations typically demonstrate a variable response. Wheat growers in the area must not only cope with this...

Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....
