“…2b), possibly due to relatively greater daily air temperatures during flowering and seed set at Hays ( Table 2). The present results support previous findings that showed increased air temperature conditions at seed development reduced oil content in camelina and other oilseed crops (Canvin, 1965;Pavlista et al, 2011;Kirkhus et al, 2013;Schulte et al, 2013).…”

“…Air temperatures and precipitation are reported to influence seed yield and fatty acid composition in oilseed crops (Canvin, 1965;Berti and Johnson, 2008;Kirkhus et al, 2013). Increased air temperature during seed development decreased seed oil content and the proportion of unsaturated fatty acids (Canvin, 1965;Schulte et al, 2013). Higher temperatures at flowering and seed formation reduced oil content in camelina but had no significant effect on fatty acid composition (Jiang et al, 2014).…”

Camelina (Camelina sativa L. Crantz) is an alternative oilseed crop with potential for fallow replacement in dryland cerealbased crop production systems in the semiarid Great Plains. Th e interaction between genotype and environment was investigated on camelina seed yield, oil content, and fatty acid composition across two locations in the U.S. Great Plains. Treatments were three spring camelina genotypes (cultivars Blaine Creek, Pronghorn, and Shoshone), three growing seasons (2013, 2014, and 2015) and two locations (at Hays, KS, and Moccasin, MT). Results showed camelina grown at Hays yielded 54% less than that at Moccasin. Blaine Creek yielded 17 and 42% more than Pronghorn and Shoshone at Hays but yields were not diff erent among genotypes at Moccasin. Oil content ranged from 262 g kg -1 at Hays to 359 g kg -1 at Moccasin. Th e proportion of polyunsaturated fatty acids (PUFAs) ranged from 51% at Hays to 55% at Moccasin, whereas monounsaturated fatty acid (MUFA) and saturated fatty acid (SFA) contents were greater at Hays. Th e linolenic acid content ranged from 26% when Pronghorn was planted at Hays to 35% when planted at Moccasin. In general, the variations in seed yield and fatty acid profi le corresponded well with growing season precipitation and temperatures at each environment.

“…High temperatures during seed filling period interfere with the activity of enzymes responsible for PUFA metabolism (Cheesbrough, 1989), thus explaining why the temperature effect on FA composition (Schulte et al, 2013) is considerable in camelina and negligible in crambe, as the latter mainly contain MUFAs (i.e., erucic acid). Laghetti et al (1995) confirmed that erucic acid is only lightly affected by environmental conditions.…”

-Social, economic and environmental importance of bio-based economy is rapidly growing and vegetable oils play an important role. About 75% of global production of vegetable oils derives from commodity oilseeds (i.e., soybean, oil palm, rapeseed), while the remaining 25% is produced from minor oilseeds characterized by unusual fatty acid composition. The present review aims at analyzing the potentialities of two alternative oilseed crops for Europe, camelina (Camelina sativa) and crambe (Crambe abyssinica), identified as major candidates for the future European bio-based economy as testified by the recently funded EU Project (Horizon 2020) COSMOS (Camelina and crambe Oil crops as Sources of Medium-chain Oils for Specialty oleochemicals). The interest on camelina and crambe is mainly due to their unique fatty acid profile, low input management and wide environmental adaptability. We attempted to analyze pros and cons of development of camelina and crambe in Europe in the light of biorefinery concept (i.e., using oil and whole produced biomass) as undertaken by COSMOS project.Keywords: Bioeconomy / oil crops / Brassicaceae / PUFA / eicosenoic acid / erucic acid Résumé -La bioéconomie, tremplin de développement pour la cameline et le crambe. L'importance sociale, économique et environnementale de l'économie reposant sur le bio, est en pleine expansion et les huiles végétales y jouent un rôle important. De l'ordre de 75 % de la production mondiale d'huiles végétales provient de graines oléa-gineuses (à savoir le soja, le palmier à huile et le colza), tandis que les 25 % restants sont produits à partir de graines oléagineuses mineures caractérisées par une composition inhabituelle en acides gras. Le présent article vise à analyser le potentiel pour l'Europe de deux cultures oléagineuses alternatives, la caméline (Camelina sativa) et le crambe (Crambe abyssinica), identifiées comme les principaux candidats à la future bio-économie européenne comme en témoigne le projet de recherche dit COSMOS (acronyme de : Camelina and crambe Oil crops as Sources of Medium-chain Oils for Specialty oleochemicals, ou Les cultures de cameline et de crambe comme sources d'huiles à chaîne moyenne pour les produits oléochimiques de spécialité) financé dans le cadre du programme Horizon 2020 de la Communauté européenne. L'intérêt porté à la caméline et au crambe est principalement lié à leur profil unique d'acides gras, à leur faible demande d'intrants et à leur large capacité d'adaptation environnementale. Nous avons tenté d'analyser les avantages et les inconvénients du développement de la caméline et du crambe en Europe à la lumière du concept de bioraffinerie (à savoir, en utilisant l'huile et toute la biomasse produite) comme dans le cadre du projet COSMOS.
