Soil salinity is one of the major abiotic stresses that adversely affect plant productivity and quality. Therefore, an experiment was conducted to investigate the effects of seed treatment with L-arginine on some morphological and physiological parameters of Brassica napus under salinity stress. The seeds of canola were pre-treated with three arginine concentrations (0, 5, and 10μM Arg) for 24 ...

Background Proteases are enzymes used in diversified process and industrial products, where the most important is the food sector and the detergent fabrication. The microbial obtention way is the most relevant, and the filamentous fungi are the main synthesis agents in industrial scale. [1]. The genres Conidiobolus, Verticillium, Penicillium e Aspergillus are reported as proteases producers. Th...

INTRODUCTION The role of the fatty acid in the prevention or progression of chronic diseases has generated significant interest on the part of researchers. Thus, our objective was to evaluate the long-term effects of high-fat diet containing soybean or canola oil on body development and bone parameters of male rats. METHODS After weaning, rats were grouped and fed either a control diet (7S) o...

This research paper investigates whether ICE futures contracts are an effective and affordable strategy to manage price risk for Canadian commodity producers in recent periods of high price volatility. Long memory in volatility is found to be present in cash and futures prices for canola and western barley. This finding is incorporated into the hedging strategy by estimating hedge ratios using ...

Many plant-associated bacteria synthesize the phytohormone indoleacetic acid (IAA). While IAA produced by phytopathogenic bacteria, mainly by the indoleacetamide pathway, has been implicated in the induction of plant tumors, it is not clear whether IAA synthesized by beneficial bacteria, usually via the indolepyruvic acid pathway, is involved in plant growth promotion. To determine whether bact...

This paper analyses the potential and limitations of airborne remote sensing systems for detecting crop growth variability and weed infestation within paddocks at specified capture times. The detection of areas of crop growth variability can help farmers become aware of regions within their paddock where they may be experiencing above and below average yields due to changes in soil or managemen...

The Ogu cytoplasm for male sterility and its fertility restorer gene Rfo in canola (Brassica napus L.) were originally introgressed from radish (Raphanus sativus L.) and have been widely used for canola hybrid production and breeding. The objective of this study was to determine the physical location of the Rfo locus in the canola genome using fluorescence in situ hybridization and genetic mapp...

Key message "We identified both quantitative and quantitative resistance loci to Leptosphaeria maculans, a fungal pathogen, causing blackleg disease in canola. Several genome-wide significant associations were detected at known and new loci for blackleg resistance. We further validated statistically significant associations in four genetic mapping populations, demonstrating that GWAS marker loc...

Oilseed crops, particularly canola, Brassica napus L., and B. rapa L., are now a major part of the prairie landscape in Canada. A diverse assemblage of arthropods can be found in areas devoted to oilseed crop production, either feeding on a resource provided by the crop, or feeding on other insects that have been attracted to these areas. Some insects prefer to feed on other plants that are gro...

The changes of Chl a fluorescence induction curve in response to different salinity levels in Canola (Barassica napus, L.) plants were investigated. The canola seedlings were exposed to salt stress (100 mM and 200 mM NaCl) for 7 days and Chl a fluorescence induction kinetics was analysed. By using the OJIP-test, various parameters like VJ, area, N, φPo, φEo, ψo, RC/ABS and PIABS were calculated...
