Magnetic gold nanoparticles (mGNPs) with uniform size and morphology synthesized by our sonication treatment method were covalently bound with fluorescein isothiocyanate (FITC) molecules. Driven by an external magnetic field, FITClabelled nanoparticles were delivered into plant cells with and without cell walls, evident from sectional transmission electron microscopy images. Confocal images fur...

208 The natural food colorants, carotenoids, are of great importance to human health. The scientists at Department of Agricultural, Food and Nutritional Science, University of Alberta, Canada enhanced the efficiency of SC-CO 2 extraction of carotenoids from carrots, by using canola oil as a continuous cosolvent. The carotenoid content of the starting material was determined by traditional solve...

Improving crop yields are essential to meet the increasing pressure of global food demands. The loss of high quality land, the slowing in annual yield increases of major cereals, increasing fertilizer use, and the effect of this on the environment all indicate that we need to develop new strategies to increase grain yields with less impact on the environment. One strategy that could help addres...

Arbuscular mycorrhizal (AM) fungi, a group of widespread fungal symbionts crops, could be important in driving crop yield across rotations through plant–soil feedbacks (PSF). However, whether preceding crops have legacy effect on the AM fungi subsequent is poorly known. We set up an outdoor mesocosm rotation experiment that consisted first phase growing either one four pre-crops establishing an...

The purpose of this study was to determine effects of feeding canola and soybean products as protein supplements on fatty acid composition of adipose tissue and muscle of slaughter bulls and steers and on fatty acid composition of kidney and liver total lipids of bulls. Products included canola meal (CM), extruded canola (EC, full-fat), ground canola (GC, full-fat), soybean meal (SBM), and extr...

Neonicotinoids currently dominate the insecticide market as seed treatments on Canada's major Prairie crops (e.g., canola). The potential impact to ecologically significant wetlands in this dominantly agro-environment has largely been overlooked while the distribution of use, incidence and level of contamination remains unreported. We modelled the spatial distribution of neonicotinoid use acros...

Several agronomic benefits can result from fall seeding of canola (Brassica spp.), but extensive research data are lacking on the potential impact of this practice on infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae), which are major pests of the crop in western Canada. Field experiments making up 13 location by year combinations were conducted in central Alberta, Canada, from 1...

In vitro incubation studies were carried out to determine if various carbohydrase preparations contained appropriate activities to target nonstarch polysaccharides (NSP) of wheat, soybean meal (SBM), canola meal, and peas. Triplicate samples (0.1 g) were incubated with a number of carbohydrase preparations (i.e., cellulase, pectinase, xylanase, glucanase, galactanase, and mannanase) or their co...

Defatted hemp, flax and canola seed cakes were extracted with different solvent systems namely methanol, ethanol, acetone, methanol 80%, acetone 80% and mixed solvent of methanol:acetone:water (MAW, 7:7:6, v/v/v). Each extract was analyzed for antioxidant capacity using ferric reducing/antioxidant power (FRAP) and 2,2-diphenyl-1picrylhydrazyl (DPPH) radical scavenging assays. MAW exhibited the ...
