Responses of barley and wheat cultivars to applications of fish- solubles and ammonium nitrate
… NH₄NO₃ on yield and components of yield of four cultivars each of barley (Hordeum vulgare) and wheat (Triticum aestivum). Both barley and wheat expressed significant yield responses to FS. The NH₄NO₃ application increased yields in both crops, although the increase in wheat was not statistically …

The effect of copper on the growth, development and chemical composition of some dryland wheat cultivars
… areas, thus it was of importance to assess the wheat cultivars (Triticum aestivum) historically used in the study areas, to ensure the viability of wheat farming. The nine wheat cultivars screened were Flameks, Knoppies, Rooiwol, Rooigys, Yecoro Royo, Charchia, Witwol, Kariega and Losper. A …

A Comparative Study of Iron and Zinc Concentration, Localization, Speciation and Bioavailability in Two Wheat Cultivars
… with the assessment of bioavailability of Fe in wheat using an in vitro Caco-2 cell model system. Speciation of Fe and Zn varied between milling fractions with low molecular weight (LMW) complexes likely to be Fe-deoxymugenic acid/nicotianamine and Zn-nictainamine being the predominant …

Evaluation of breadmaking quality from common wheat quality parameters and fundamental rheological, chemical, and functional properties of wheat cultivars
… stress relaxation and deformability modulus of wheat doughs made from five groups of wheat cultivars of differing breadmaking ability were determined. Doughs made from poor breadmaking cultivars had greater rates of stress relaxation than doughs made from good breadmaking cultivars. Doughs made …

Variation for root and shoot growth among wheat cultivars and the effects of barley yellow dwarf virus on growth
Studies were conducted on eight soft red winter wheat cultivars to evaluate differences in root growth, to evaluate the effects of barley yellow dwarf virus (BYDV) on root and shoot growth, and to study the effects of a plant growth regulator on root growth of healthy and BYDV infected plants. …

Root Rot Pathogens of Wheat in South Dakota and Their Affect on Seed Germination and Seedling Blight in Spring Wheat Cultivars
… root rot are the important root diseases in wheat (<em>Triticum aestivum</em> L.) and other cereals causing significant germination and yield losses in the Northern Great Plains and other parts of the world. <em>Bipolaris sorokiniana</em> (Bs) and <em>Fusarium graminearum</em> (Fg) cause …

Studies on improvement of Chinese wheat cultivars for resistance against an endemic virus using transgenesis and virus-wheat interactions at the molecular and ultrastructural levels
… study was aimed at the improvement of Chinese wheat cultivars for resistance to Soil-borne wheat mosaic virus (SBWMV) by transgenesis, and an examination of virus movement by studying the complementation of movement proteins (MPs) from Tobacco mosaic virus (TMV) and SBWMV using a TMV-based …

Effects of wheat streak mosaic virus and interactions with other cereal viruses on wheat
… of plants. The effects of an Illinois isolate of wheat streak mosaic virus (WSMV) on yield of selected hard red spring wheat and soft red winter wheat cultivars were evaluated in three studies. In spring and fall of 1993 and 1994, twenty hard red spring wheat cultivars and fourteen soft winter …

Investigating the role of the circadian clock in the physiology of wheat
… targets for breeders looking to create new elite wheat cultivars. The first aim of this thesis was to identify naturally occurring variation in circadian clock genes across wheat cultivars important in modern breeding efforts. In Arabidopsis, LUX ARRYTHMO (LUX) and EARLY FLOWERING 3 (ELF3) are …

Evaluation of alpha-amylase activity and falling number for soft white and soft red wheat varieties adapted to Michigan
… (PHS) is a major threat to Michigan soft white wheat, and recent epidemics were experienced in 2008 and 2009. Alpha-amylase is an important component of PHS and the falling number (FN) test is used by industry to identify sprouted wheat that is unacceptable for various food products. The …

Development of new tools and germplasms for improvement of wheat resistance to Fusarium head blight
Wheat Fusarium head blight (FHB) is a devastating disease of wheat worldwide, which can significantly reduce grain yield and quality. Although the application of fungicides can reduce FHB damage, growing FHB resistant wheat is the most effective and eco-friendly approach to reduce the losses. To …

Effect of different sprouting conditions on alpha amylase activity, functional properties of wheat flour and on shelf-life of bread supplemented with sprouted wheat
In this study sprouting two different wheat cultivars under various environmental conditions revealed that varietal variation is the most important factor affecting α-amylase quantity as well as quality to modify flour functionality significantly, followed by pre-soaking duration and temperature. …

Comparison of the effects of reducing light intensity after flag leaf emergence in two wheat cultivars, Triticum Aestivum cv. Karamu and Triticum Aestivum cv. Arawa: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science (Hons.) in the University of Canterbury
… derivatives is different from that of standard wheat cultivars. Light is a factor that is important in the development of the inflorescence, so the aim of this experiment is to see if Karamu is more affected by a drop in light intensity than is any of the standard cultivars, and to see if any …

Characterization of Hessian fly from Israel
… family Cecidomyiidae. It is a common pest of wheat found throughout all of the major wheat growing areas of the world and poses a serious economic threat to the United States (US), particularly in the Southeast winter wheat region. Damage to wheat is done solely by feeding first and second …

Genotypic characterization and fungicide resistance monitoring for Virginia populations of Parastagonospora nodorum in wheat
… blotch (SNB), is a major foliar disease of wheat in the mid-Atlantic U.S., is caused by the necrotrophic fungus Parastagonospora nodorum. SNB is managed using cultural practices, resistant varieties, and foliar fungicides. There are increasing trends of severity and incidence of SNB in …

Exploring relationships between root architecture and growth of UK wheats (Triticum aestivum L.)
… the grain filling period, growing deep rooting cultivars increased wheat yields by approximately 15%. Seedling root angle is associated with adult root system depth in Australian field-grown wheat cultivars (Triticum aestivum L.), but it is not yet known whether selection for root angle and …

Genetic and Environmental Responses of Harvest Index and Other Agronomic Traits in Winter Wheat (Triticum Aestivum L.) and Spring Oats (Avena Sativa L.)
Two experiments conducted with winter wheat and spring oats investigated the potential of several agronomic traits, especially harvest index, total dry matter production, and growth rate, for improving grain yield. The effect of four nitrogen fertilizer treatments on harvest index, grain yield, …
