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...
Differential exudation of polypeptides by roots of aluminum-resistant and aluminum-sensitive cultivars of Triticum aestivum L. in response to aluminum stressDownload
Cultivars of Triticum aestivum differing in resistance to Al were grown under aseptic conditions in the presence and absence of Al and polypeptides present in root exudates were collected, concentrated, and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Upon exposure to...
Induction of microsomal membrane proteins in roots of an aluminum-resistant cultivar of Triticum aestivum L. under conditions of aluminum stressDownload
Three-day-old seedlings of an Al-sensitive (Neepawa) and an Al-resistant (PT741) cultivar of Triticum aestivum were subjected to Al concentrations ranging from a to 100 mu M for 72 h. At 25 mu M Al, growth of roots was inhibited by 57% in the Al-sensitive cultivar, whereas root growth in the...
Estimation of Source- and Quality-Differentiated Import Demand Under Aggregate Import Quota: An Application to Japan's WheatDownload
Since a seminal work by Armington (1969), estimating source-differentiated import demand has become a useful tool in applied international trade research. Trade policy evaluation and simulation require reliable estimates of the responsiveness of import demand to international price changes....
Quantitative information on the uptake and distribution of Al at the cellular level is required to understand mechanisms of Al toxicity, but direct measurement of uptake across the plasma membrane has remained elusive. We measured rates of Al transport across membranes in single cells of Chara...
Optimizing exponential growth of Triticum aestivum by application of the relative addition rate (RAR) technique utilizing a computer-controlled nutrient delivery systemDownload
We conducted experiments designed to assess whether plants can be grown under conditions of low ionic strength simulating natural soil conditions. Wheat (Triticum aestivum, cv. Atlas 66) plants were grown using ten different relative nutrient addition rates (RAR) of nutrients (0.00, 0.06, 0.09,...
This paper reports on a review of literature in the form of academic papers and published research on ethical and consumer issues for GM crops in North America, with particular emphasis on GM wheat. The issues raised in these papers and the findings and arguments posed by the authors are...
