Oomah, B.D. | Kenaschuk, E.O. | Mazza, G.
Lipoxygenase content of meal from eight flaxseed cultivars grown for 3 years at four locations in western Canada was evaluated to examine genotypic and environmental effects. Flaxseed, on average, contained 1.6-6.0 g of lipoxygenase/kg of meal. Lipoxygenase content in flaxseed was cultivar specific and strongly influenced by environmental conditions. Variation in lipoxygenase content was predominantly due to cultivar x location x year interaction. Seasonal differences in lipoxygenase enzyme content were significant at most locations. In flaxseed, lipoxygenase content was independent of oil and protein contents but was inversely related to the kinetic lag period. The lipoxygenase enzyme was expressed mainly in the embryo with only partial enzyme expression in the seed coat or hull of flaxseed.
