Unweathered crop residues can produce growth-inhibiting substances, stimulate pathogen growth, and immobilize nutrients. The location of seed relative to residue may be an important factor in the early health of a crop. This greenhouse study simulated sowing conditions possible under annual dryland winter wheat (Triticum aestivum L.) production to evaluate the likelihood of inhibitory effects. ...

Nascent allohexaploid wheat may represent the initial genetic state of common wheat (Triticum aestivum), which arose as a hybrid between Triticum turgidum (AABB) and Aegilops tauschii (DD) and by chromosome doubling and outcompeted its parents in growth vigor and adaptability. To better understand the molecular basis for this success, we performed mRNA and small RNA transcriptome analyses in na...

Soil texture is an important environmental factor that influences the crop productivity of wheat (Triticum aestivum) because it provides all nutrients required for growth plants. The soil based on classified into four classes: silt, clay, sand, and loam. mineral particles was by United States Department Agriculture (USDA). According to USDA, loam have a size between sand (2.00–1.0 mm) silt (0.0...

Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced norma...

256 Journal of Plant Registrations, Vol. 3, No. 3, September 2009 ’Camelot ‘ (Reg. No. CV-1036, PI 653832) hard red winter wheat (Triticum aestivum L.) was tested under experimental line number NE01604 and was developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA–ARS and released in April 2008 by the developing institutions. Camelot will be marketed through the Nu...

Pigment-protein complexes separated from wheat (Triticum aestivum L. selection ND96-25 by two gel electrophoresis techniques were analyzed by high-performance liquid chromatography for chlorophylls and carotenoids. The two techniques are compared, and pigment analyses are given for the major reaction centers and light-harvesting complexes. Reaction centers contain mostly chlorophyll a, carotene...

Light-grown 7-day-old wheat seedlings (Triticum aestivum, var. Maris Dove) showed an increase of 200% in plastids per cell between 1.7 and 4.5 centimeters from the leaf base. This increase was the result of divisions of young chloroplasts at various stages of development, and was well separated in distance, and therefore in time from the region of cell division in the basal meristem. [(3)H]Thym...

Abstract: Increased crop density and use of herbicides are two important components of integrated weed management program in wheat but no much information is available on combined effects of these two treatments. A field experiment was conducted to determine the interaction effect of increasing seed rates and weed management treatments on monocot and dicot weeds, grain and straw yield and uptak...
