Cadmium uptake and translocation in seedlings of near isogenic lines of durum wheat that differ in grain cadmium accumulationDownload
Background Cadmium (Cd) concentrations in durum wheat (Triticum turgidum L. var durum) grain grown in North American prairie soils often exceed proposed international trade standards. To understand the physiological processes responsible for elevated Cd accumulation in shoots and grain, Cd...
Differential aluminum tolerance of high-yielding, early maturing Canadian wheat cultivars and germplasmDownload
Twenty-eight spring wheat (Triticum aestivum) cultivars were tested for tolerance to aluminum (Al) using solution culture techniques. Fourteen of these cultivars were also grown in the fietd under two different management levels, Conventional and Intensive Crop Management (ICM), to determine...
Formation and Morphology of an Iron Plaque on the Roots of Typha latifolia L. Grown in Solution Culture.Download
Roots of Typha latifolia L. exposed to Fe2+ under reduced conditions in solution culture developed visible coatings (plaques) of an oxidized Fe compound that extended as much as 15-17 ,um into the rhizosphere. Iron concentrations were significantly less and discoloration was not apparent on the...
Mechanisms of Aluminum Tolerance in Triticum aestivum L. (Wheat). I. Differential pH Induced by Winter Cultivars in Nutrient Solutions.Download
Twenty winter cultivars of Triticum aestivom L. (wheat) were grown in solution culture with and without aluminum (A1) (74 gM, 2.0 mg L-') for 14 days. Exposure to s increased root growth of the most tolerant cultivar, while both root and shoot growth were depressed in all other cultivars. On the...
Mechanisms of Aluminum Tolerance in Triticum aestivum L. (Wheat). II. Differential pH Induced by Spring Cultivars in Nutrient Solutions.Download
Twenty spring cultivars of Traticum aestivum L. (wheat) were grown in solution culture with and without aluminum (A1) (74 gM, 2.0 mg L-l) for 14 days. Root growth and shoot growth were depressed in all cultivars grown with A1; however, symptoms of A1 toxicity were most evident on roots. Based on...
Response of eight Canadian spring wheat (Triticum aestivum L.) cultivars to copper: Copper content in the leaves and grainDownload
Concentrations of copper (Cu) in the youngest fully emerged leaves (YFEL) and grain of eight widely grown Canadian spring wheat (Triticum aestivum L.) cultivars, Biggar, Columbus, Conway, Katepwa, Laura, Oslo, Park and Roblin, were determined. l,eaves were sampled at five growth rtulE f.o. field...
Response of eight Canadian spring wheat (Triticum aestivum L.) cultivars to copper: Pollen viability, grain yield plant-1 and yield componentsDownload
Eight Canadian spring wheat (Triticum aestivum L.) cultivars, Katepwa, Roblin, Park, Laura, Conway, Oslo, Columbus and Biggar., were tested in the field for copper (Cu) use efficiency. The experiment was conducted at Stony Plain, Alberta on an Orthic, Dark Grey, Chernozemic, Cu deficient 10.48 pg...
Replicate samples of Phragmites communis roots coated with hydrous iron oxide were analyzed for internal and external Fe using the dithionite-citrate-bicarbonate technique (hot DCB), a modified DCB technique (cold DCB), Ethylenediaminete traacetic acid (EDTA), Diethylenetriamine pentaacetic acid...
