Contribution of Dockage (admixture) to the Chlorophyll Content of Canadian Canola Exports
نویسندگان
چکیده
The 2004 Harvest Survey of Canadian canola (1) had higher than average chlorophyll content due to a cooler than normal season combined with an early damaging frost resulting in immature seed. As a result, chlorophyll levels in many No. 1 Canada Canola (1CC) export shipments increased to over 30 mg/kg (2). Dockage has been suspected in contributing to the chlorophyll levels in canola cargoes but until this study, the extent was unknown. Dockage separated from export samples was tested for chlorophyll using the ISO method. Chlorophyll in the dockage ranged from 67 to 114 mg/kg. With dockage removed, the chlorophyll level in 1CC export samples was approximately 3.5 mg/kg lower.

Comparison between Canadian Canola Harvest and Export Surveys
Parameters, such as oil, protein, glucosinolates, chlorophyll content and fatty acid composition, were determined using reference methods for both harvest survey samples and Canadian Canola exports. Canola harvest survey and export data were assessed to evaluate if canola harvest survey data can be extrapolated to predict the quality of the Canadian canola exports. There were some differences i...
متن کاملDetection of Leptosphaeria maculans and Leptosphaeria biglobosa Causing Blackleg Disease in Canola from Canadian Canola Seed Lots and Dockage.
Blackleg, caused by Leptosphaeria maculans, is a major threat to canola production in Canada. With the exception of China, L. maculans is present in areas around the world where cruciferous crops are grown. The pathogen can cause trade barriers in international canola seed export due to its potential risk as a seed contaminant. The most recent example is China restricting canola seeds imported ...

In this experiment, the possibility of growth promoting of exogenous salicylic acid during two growth stages on chlorophyll content, yield and yield components of canola plant was investigated. For the purpose of improving above traits, salicylic acid was applied in four concentrations (0, 100, 200 and 400 µM) during two different growing stages (first time; when temperature was close to 7-10 °...
