Influence of different nitrogen and moisture levels on the expression of grain yield and protein content in selected wheat (Triticum aestivum, L. em Thell) and barley (Hordeum vulagre, L. em Lam.) cultivars

Creator:: Gomez-Pando, Luz
Abstract:: This investigation was conducted to provide information regarding 1) the relationship between the nitrogen percentage in the vegetative tissue of wheat and barley at various growth stages with grain protein and 2) to evaluate the possible association between grain yield and grain protein as influenced by different cultivars, nitrogen levels...

Endosperm morphogenesis in wheat (Triticum aestivum L.)

Creator:: Huber, Andrew Gail, 1944-
Abstract:: Wheat endosperm morphogenesis was studied by light microscopy during the entire growth period of anthesis to maturity. Four developmental stages have been described in this thesis: (1) double fertilization, (2) formation of the lower endosperm cells, (3) termination of nuclear divisions, and (4) initiation of protein bodies. The first manuscript...

Growth rate and phosphorus uptake of wheat (Triticum aestivum VILL., Host) as a function of soil water suction and soil temperature

Creator:: Fazilat, Mohammad
Abstract:: The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL. , Host) was studied. Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable membrane. Measurements were made at temperatures of 10.0, 18.3,...

Nitrogen uptake by wheat (Triticum aestivum VILL., Host) as a function of root temperature and plant water stress

Creator:: Sepaskhah, Ali Reza
Abstract:: The effect of soil temperature and plant water stress on nitrogen uptake, growth rate and transpiration rate of wheat (Triticum aestivum VILL. , Host) seedlings was studied. A special apparatus for the control of plant water stress and root temperature was used. Leaf area was measured by the air flow...

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...
Resource Type:: Dissertation
Full Text:: elimination of material with low potential is needed. Such a method is clearly advantageous due to

Effect of seed protein content on plant growth of barley and wheat

Creator:: Lopez, Arturo
Abstract:: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

Combining ability and gene action estimates and the association of the components of yield in winter wheat crosses

Creator:: Kronstad, Warren E. (Warren Ervind), 1932-
Abstract:: A diallel cross consisting of ten parents was grown on the Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain estimates of the gene action contributing to yield and its components in wheat. Gene action estimates were obtained by two methods of diallel analysis and from narrow sense heritability...

The influence of various climate and edaphic factors on the toxicity of 2-tert. butylamino-4-ethylamino-6-methylthio-s-triazine (Igran) to winter wheat (Triticum aestivum Vill., Host)

Creator:: Figuerola, Luis Fernan
Abstract:: Several studies were conducted to determine the influence of various environmental factors on the toxicity of 2-tert.butylamino- 4-ethylamino-6-methylthio-s-triazirxe (Igran) to winter wheat. The effect of temperature on Igran toxicity was studied by growing wheat plants in pots submerged in water baths to control soil temperature and in controlled-environment chambers. Igran...

The effect of fertility level on plant growth and development, water uptake and water stress in dryland wheat production

Creator:: Agamennoni, Raul Jose
Abstract:: Dryland winter wheat in eastern Oregon is usually subjected to water stress several times during the growing period. Moreover, the last three months of growth period depend strongly on the available soil water. The fertility level, stage of growth, availability of soil water and climatic conditions all interact to determine...

A study of methods of parental evaluation using testers to predict subsequent progeny performance in winter wheat (Triticum aestivum L.)

Creator:: Alexander, William Larry
Abstract:: The major objective of this study was to determine why certain winter wheat cultivars, when hybridized, will produce a greater proportion of desirable plants in subsequent, segregating generations. Three winter wheat parents were chosen as the experimental material, based on their known performance as parents. Yamhill and Pullman Selection 101...
