abstract the use of plants for remediation of heavy metals contaminated soils is an economical, cheap and effective strategy. this research was conducted in order to study the effect of potassium chloride on cadmium uptake and enhancement of it's phytoremediation by canola (brassica napus l.) and sunflower (helianthus annuus l.) in a cadmium polluted soil from angoran in zanjan province. in a r...

Blackleg, also known as Phoma stem canker, caused by Leptosphaeria maculans (Phoma lingam), is one of the most serious diseases of canola worldwide. In this study, the mean disease severity (Ds) and incidence (Di) of canola cv. Westar plants infected at the cotyledon, three-leaf, and six-leaf stages by pycnidiospores of L. maculans were monitored in the greenhouse after infection of the plants ...

________________________________________________________________________________ Abstract Dietary conjugated linoleic acid (CLA) causes adverse effects on quality of eggs by modifying the fatty acid composition of the yolk. Supplementing oils prevent CLA-induced changes, but cause a decrease in the level of egg CLA. The objective of the study was to investigate the incorporation of CLA into the...

We conducted a long-term investigation to ascertain effects on honey bee, Apis mellifera L., colonies during and after exposure to flowering canola, Brassica napus variety Hyola 420, grown from clothianidin-treated seed. Colonies were placed in the middle of 1-ha clothianidin seed-treated or control canola fields for 3 wk during bloom, and thereafter they were moved to a fall apiary. There were...

Clubroot disease is one of the most serious diseases of Brassica species, which is caused by soil-borne pathogen Plasmodiophora brassicae Woronin. Clubroot disease has a long history on vegetable crops belonging to the Brassica species; most recently, this disease is also invading rapeseed/canola crop around the globe. The clubroot disease causes significant yield and quality losses in highly i...

We have generated a Brassica napus (canola) population of 3,158 EMS-mutagenised lines and used TILLING to demonstrate that the population has a high enough mutation density that it will be useful for identification of mutations in genes of interest in this important crop species. TILLING is a reverse genetics technique that has been successfully used in many plant and animal species. Classical ...

In this study, bacteria were isolated from the rhizosphere and inside the roots of canola (Brassica napus L.) plants grown in the field from northern Iran. Firstly, 150 strains (endophytic and rhizospheric isolates) isolated from canola were characterized for plant growth promoting (PGP) traits. Of them, one hundred isolates produced indole3-acetic acid (IAA), whereas 17 isolates solubilized ph...

Lodging, defined as the permanent displacement of aboveground parts, is a common problem to cause yield loss, deterioration in seed quality and difficult to harvest in canola (Brassica napus L.) crop production. This study aimed to develop a method for assessing crop lodging, to examine how agronomic practices affected the relationships between root lodging and electrical capacitance traits. Ca...

The impact of feed processing and in vitro ruminal cultures on the persistence of recombinant and canola-specific endogenous DNA was studied using various canola substrates (whole seed, cracked seed, meal and diet). For both, parental and genetically modified substrates, ribulose-1,5-bisphosphate carboxylase/oxygenase gene was amplifiable up to varying time points. Persistence of recombinant DN...

Blackleg disease of canola in western Canada has been effectively managed for the past 20 years through a combination of resistant varieties, adequate crop rotation intervals and good agronomics. Increased canola production in western Canada, in large measure through more frequent cropping in the rotation, has increased the risk that resistance to blackleg in current varieties may be defeated. ...
