“…Nitrogen and sulphur nutrition have also been shown to affect oil and protein concentration and fatty acid composition of B. napus seed (Appelqvist 1968). Additionally, photoperiod and light intensity have been shown to affect fatty acid composition in flax (Dybing and Zimmerman 1966). Frost damage during ripening of canola has been shown to reduce oil and C18:3 concentration and increase C16:0 and free fatty acid concentration, presumably by prematurely terminating seed maturation (Daun et al 1985).…”

environmental effects on saturated fatty acid concentration of canola grown in Manitoba. Can. J. Plant Sci. 84: 749-756. The low saturated fatty acid concentration of canola oil relative to other vegetable oils has resulted in a favourable market share for canola. Understanding the effects of genotype and environment on saturated fatty acid concentration will facilitate Brassica napus breeding efforts aimed at maintaining or reducing saturate levels in the seed oil. Canola-quality B. napus samples from the Manitoba Crop Variety Evaluation Team (MCVET) trials in 1999, 2000 and 2001 were tested for fatty acid composition, oil concentration and protein concentration. Weather data were obtained from nearby weather stations. The majority of the variation in total saturates for the cultivars studied was attributed to variation in palmitic acid (C16:0) due to the genotype main effect and variation in stearic acid (C18:0) due to the genotype and environment main effects. The variation due to the genotype × environment interaction was small relative to the main effects for the individual saturated fatty acids. C18:0 and arachidic (C20:0) acid concentrations were correlated between genotypes, suggesting pleiotropy or that these traits are controlled by linked genes in the cultivars tested. The data also suggested that C16:0 and C18:0 acid concentrations are controlled by different genes. C18:0, C20:0 and behenic (C22:0) acid concentrations were correlated across environments, but did not correlate with C16:0 concentration. Relationships between weather variables and fatty acid composition, oil concentration and protein concentration were not established. Additive Main effects and Multiplicative Interaction (AMMI) analysis revealed that some canola cultivars were more stable than others with regard to total saturates over environments.

“…The growing area of linseed was a little less than 2 000 ha in 2005 in Finland (Anneli Partala, Information Centre of the Ministry of Agriculture and Forestry, personal communication). There are some advantages to growing linseed in the northern latitudes, as the content of linolenic acid and omega-3 fatty acids in the oil are higher in linseed grown in cool temperatures typical for northern countries compared to southern countries (Dybing and Zimmerman 1966). However, the effect of northern production of linseed on other quality properties has not been published.…”

In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% α-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed grown in northern latitudes. The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably for linseed oil. This variation depends mainly on differences in the examined varieties and industrial processing treatments. The fatty acid composition leads also to some problems, rancidity probably being the most challenging. Some information has been published concerning oxidation and taste, whereas only a few studies have focused on colour or microbiological quality. Rancidity negatively affects the taste and odour of the oil. There are available a few studies on effects of storage on composition of linseed oil. In general, storage and heat promote auto-oxidation of fats, as well as decrease the amounts of tocopherols and vitamin E in linseed oil. Several methods are available to promote the quality of the oil, including agronomic methods and methods of breeding as well as chemical, biotechnological and microbiological methods. Time of harvesting and weather conditions affect the quality and yield of the oil.

“…Studies of flax and temperature have been reported a lot, but these focused mainly on the effect of different temperatures on seed germination, plant growth, seed yield and oil composition of oilseed flax (Dybing and Zimmerman, 1965;Dybing and Zimmerman, 1966;Green, 1986;O'Connor and Gusta, 1994;Casa et al, 1999;Saeidi and Rowland, 1999;Kurt and Bozkurt, 2006). In fiber flax, Yang et al (2013) only reported that diurnal temperature range (DIF) had a significant influence on the agronomic traits.…”

“…While, in other study Dybing and Zimmerman (1965) concluded that high temperatures could reduce the number and weight of seeds, and even decrease oil quality of flax during the seed ripening period under controlled environments. And temperature is also customarily assigned a major role in regulation of fatty acid composition of flax oilseeds (Dybing and Zimmerman, 1966).…”

Three flax (Linum usitatissimum L.) cultivars ('Ariane', 'Argos' and 'Viking') were used to study the effect of diurnal temperature range (DIF) applied throughout the whole growth stage on the development of fiber cells. Diurnal temperature ranges were set at 5C, 10C and 15C with the same daily mean temperature and accumulated growing degree days (GDDa). All measured traits showed obvious DIF and varietal differences except the length of fiber bundle (LFB) and the inter-fiber bundle distance (IFBD). Significant interactions of DIF and cultivar were observed to affect the width of fiber bundle (WFB), the size of fiber cell (SFC), the size of fiber cell cavity (SFCC) and the thickness of fiber cell wall (TFCW). Compared with other DIFs, the number of fiber cells per bundle (NFCB) and WFB increased, but IFBD decreased under DIF 5. However, WFB, TFCW and NFCB all decreased under DIF 10. Under DIF 15 condition, both SFC and SFCC increased. For 'Ariane', IFBD was short under DIF 5, but SFC and SFCC were both large under DIF 10. For 'Argos', IFBD was also short under DIF 5. Under DIF 10, WFB, SFC and TFCW were all small, but IFBD was long. For 'Viking', TFCW was small under DIF 10 but large under DIF 15. All these results suggested a definite influence of DIF on the development of fiber cells in flax, and DIF set at 5°C benefited the number of fiber cells in a bundle but DIF 15 was optimal for the size of fiber cells.
