Actual and predicted response to selection on maternally influenced traits in the mouse

Creator:: Lind, Ronald Egnard
Abstract:: An experiment was conducted to determine if selection from standardized litters would be effective in separating lines of mice selected for increased and decreased litter weight at 14 days of age, and if response to selection on this maternally influenced trait could be accurately predicted. Data were collected on litter...

Ecotypic adaptation of Setaria lutescens (Weigel) F. T. Hubbard to alfalfa culture in California

Creator:: Schoner, Carl Arnold
Abstract:: Setaria lutescens (yellow foxtail) plants, grown from five seed sources were compared in California. Seed sources were: Connecticut, Iowa, Massachusetts, Pennsylvania and California. Morphological and physiological differences between biotypes include: plant size, growth habit, time required to mature and reproductive capa city. Most significant is the prostrate habit of the...

Heritability estimates and associations for protein content and grain yield involving four winter wheat crosses (Triticum aestivum Vill., Host)

Creator:: Solen, Polat
Abstract:: Four agronomically and genetically diverse winter wheat parents were utilized as the experimental organisms. Atlas 66 and NB 68513 were selected as cultivars with a high and stable protein content when grown under different environmental condidtions. They are intermediate for grain yield when grown in the Pacific Northwest. Yamhill and...

Growth and reproductive development in selected cultivars of Kentucky bluegrass given different durations of exposure to floral inductive conditions

Creator:: Turner, J. Kevin
Abstract:: Kentucky bluegrass (Poa pratensis L.) cultivars are known to differ quantitatively in their photothermal floral inductive requirements. The extent to which these requirements are met influences the potential for subsequent panicle exsertion. A better understanding of the inductive requirements as they vary among cultivars would aid in the selection and...

Exogenous and endogenous factors related to seed germination and vigor in certain varieties of sugarbeet Beta vulgaris L.

Creator:: Kim, Syng Chul
Abstract:: Studies were conducted on the causes of low germination of monogerm sugarbeet seed grown in western Oregon. Emphasis was placed on the identification and measurement of endogenous inhibitors as related to the germination and vigor. Both qualitative and quantitative analytical methods were applied to examine the organic substances in the...

Influence of post-harvest management practices on plant growth and seed yield of cool season grasses

Creator:: Stanwood, Phillip Charles
Abstract:: Field and controlled environment chamber studies were carried out to evaluate modes of action of post-harvest treatments on the development and seed yield of cool season grasses. Red fescue (Festuca rubra L.) was used as the primary test species. There was no difference in total biomass production of red fescue...

Influence of post-harvest burning, thinning, shading and residue management on the subsequent growth and seed yield of Festuca rubra L.

Creator:: Kim, Syng Chul
Abstract:: The effects of post-harvest burning of red fescue on production of shoots, roots and inflorescences as well as seed yield were determined at the clonal and community level by comparing fescue plants in a burned area with those in unburned plots within the same field. Studies were also conducted to...

Effect of production methods on quality of wheat seed

Creator:: Mathenge, Felix Njeruh
Abstract:: The objective of this research was to identify the optimum cultural practices for the production of the highest quality wheat seed in Oregon. The production methods included locations, irrigation, N levels and seeding rates. The seed quality factors studied were seed weight, bushel weight, protein content and seedling vigor. Foundation...

The effects of ryegrass straw and monensin on performance of feedlot lambs

Creator:: Shqueir, Adnan Ali
Abstract:: The objectives of this study were to investigate the effects of the by-product, ryegrass straw, and the feed additive, monensin, on the performance of feedlot lambs. Four pelleted rations were fed ad libitum: Ration 1 - 50% barley, 50% alfalfa hay; Ration 2 - 50% barley, 50% alfalfa hay and...

Cyperus esculentus control with glyphosate : time of application and addition of ammonium sulfate

Creator:: Costa, Jaime
Abstract:: Cyperus esculentus L. var. esculentus is a serious weed problem in northwest Spain. Long-term control from glyphosate and other herbicides has been inconsistent. Field, greenhouse, and laboratory studies were conducted on factors influencing the activity of glyphosate on C. esculentus. In field studies, glyphosate controlled foliage growth at most growth...
