Spring 2010
Intercropping systems offer potential benefits relative to monocultures of increased crop yields and improved pest control through physical, chemical, or behavioural interference and the enhancement of natural enemy populations, prompting increased predation and parasitism. Intercrops of canola...

Lab-on-a-Chip Designs for Airborne Spore Detection: Towards the Forecasting of Sclerotinia Stem Rot of Canola
DownloadFall 2022
Sclerotinia stem rot (SSR), caused by the necrotrophic fungal pathogen Sclerotinia sclerotiorum, is one of the most devastating diseases affecting crops. More than 400 plant species around the globe are affected by this fungus. In canola, one of Canada’s most important crops, yield losses due to...

Modeling stomatal and nonstomatal effects of water deficits on CO2 fixation in a semiarid grassland
Download2007
The confidence with which we can model water deficit effects on grassland productivity is limited by uncertainty about the mechanisms, stomatal and nonstomatal, by which soil water deficits reduce CO2 uptake. We propose that these reductions can accurately be modeled from a combination of...

Monitoring Airborne Inoculum of Sclerotinia sclerotiorum at Canola Flowering and Relationships to Weather Conditions and Disease Incidence and Severity
DownloadFall 2022
Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is an important disease of canola (Brassica napus). Disease development is highly dependent on weather conditions and is initiated by infection of the petals by airborne ascospores, followed by mycelial progression into leaf and stem...

Terrestrial vegetation contributes strongly to dynamic biosphere-atmosphere exchanges of mass and energy, through activities such as photosynthesis, that help shape the Earth’s climate. The boreal forest is located in high latitudes and subject to large seasonal temperature fluctuations and a...

Monitoring year-to-year variability in dry mixed-grass prairie yield using multi-sensor remote sensing
DownloadFall 2012
The Normalized Difference Vegetation Index (NDVI) and harvested biomass were compared to assess rangeland productivity (above-ground green biomass or “yield”) in southern Albertan dry mixed-grass prairie. Seasonal trends during the 2009 and 2010 growing seasons were investigated using harvested...

Seneviratne, Ruwani Wickramasooriya
The nutritional value of biodiesel co-products were studied for swine. In Exp. 1, expeller-pressed canola meal was nutritionally characterized and validated for grower-finisher pigs. Expeller-pressed canola meal provided adequate energy and AA; ADG was reduced 3 g/d per 1% expeller-pressed canola...

Fall 2020
Canola (Brassica napus L.) is an amphidiploid or allotetraploid (AACC, 2n = 4x = 38) crop plant and it is one of the most important oilseed crops in the world. The narrow genetic base of this crop, especially in its C genome, is not only a major impediment for its continued improvement but also...

Progress towards the sustainable risk management of clubroot (Plasmodiophora brassicae) of canola on the Canadian prairies
Download2011-01-01
Strelkov, Stephen E., Hwang, Sheau-Fang, Howard, Ronald J., Hartman, Murray, Turkington, T. Kelly
Clubroot, caused by the obligate parasite Plasmodiophora brassicae Woronin, has recently emerged as an important disease of canola (Brassica napus) in central Alberta. Disease development is characterized by the formation of large galls on the roots of affected plants, which hinder water and...
