    Reprinted from: Issues in new crops and new uses. 2007. J. Janick and A. Whipkey (eds.). ASHS Press, Alexandria, VA. Camelina sativa, A Montana Omega-3 and Fuel Crop* Alice L. Pilgeram, David C. Sands, Darrin Boss, Nick Dale, David Wichman, Peggy Lamb, Chaofu Lu, Rick Barrows, Mathew Kirkpatrick, Brian Thompson, and Duane L. Johnson Camelina sativa (L.) Crantz, (Brassicaceae), commonly known as false flax, leindotter and gold of pleasure, is a fall or spring planted annual oilcrop species (Putman et al. 1993). This versatile crop has been cultivated in Europe since the Bronze Age. Camelina seed was found in the stomach of Tollund man, a 4th century BCE mummy recovered from a peat bog in Denmark (Glob 1969). Anthropologists postulate that the man’s last meal had been a soup made from vegetables and seeds including barley, linseed, camelina, knotweed, bristle grass, and chamomile. The Romans used camelina oil as massage oil, lamp fuel, and cooking oil, as well as the meal for food or feed. Camelina, like many Brassicaceae, germinates and emerges in the early spring, well before most cereal grains. Early emergence has several advantages for dryland production including efficient utiliza- tion of spring moisture and competitiveness with common weeds. In response to the resurgent interest in oil crops for sustainable biofuel production, the Montana State Uni- versity (MSU) Agricultural Research Centers have conducted a multi-year, multi-specie oilseed trial. This trial included nine different oilseed crops (sunflower, safflower, soybean, rapeseed, mustard, flax, crambe, canola, and camelina). Camelina sativa emerged from this trial as a promising oilseed crop for production across Montana and the Northern Great Plains.

  • Novel Mutant Camelina and Jatropha As Valuable Feedstocks for Biodiesel
    www.nature.com/scientificreports OPEN Novel mutant camelina and jatropha as valuable feedstocks for biodiesel production Muhammad Mahran Aslam1, Asif Ali Khan1,2, Hafza Masooma Naseer Cheema1, Muhammad Asif Hanif3*, Muhammad Waqar Azeem3 & Muhammad Abubakkar Azmat4 Novel mutant camelina has become a crop of interest inspired by its short growing season, low harvesting costs and high oil composition. Despite those advantages, limited research has been done on novel mutant lines to determine applicability for biodiesel production. Jatropha is an extremely hardy, frugal and high oil yielding plant species. The major aim of the present study was not only to compare biodiesel production from jatropha and camelina but was also to test the efcacy of camelina mutant lines (M6 progenies) as superior feedstock. The biodiesel yield from camelina oil and jatropha oil was 96% and 92%, respectively. The gas chromatographic analysis using fame ionization detector (GC-FID) showed that mutant camelina oil biodiesel sample contain major amount of oleic acid (46.54 wt%) followed by linolenic acid (20.41 wt%) and linoleic acid (16.55 wt%). Jatropha biodiesel found to contain major amount of oleic acid (45.03 wt%) followed by linoleic acid (25.07 wt%) and palmitic acid (19.31 wt%). The fuel properties of produced biodiesel were found in good agreement with EN14214 and ASTM D6751 standards. The mutant camelina lines biodiesel have shown comparatively better fuel properties than jatropha. It has shown low saponifcation value (120.87–149.35), high iodine value (130.2–157.9) and better cetane number (48.53–59.35) compared to jatropha biodiesel which have high saponifcation value (177.39–198.9), low iodine value (109.7– 123.1) and lesser cetane number (47.76–51.26).

A split-plot design, with sowing date as main plot (autumn and spring) and cultivar (V1, V2, V3, V4, V5, V6, and CELINE) as subplot, was adopted over two growing seasons (2017–2019). Phenology, yield and yield components, protein and oil content, and fatty acid profile were evaluated. Going from autumn to spring sowing, a significant reduction was observed in the number of days (139 vs. 54 days) and GDD (642 vs. 466 ◦C d) from emergence to beginning of flowering, with more consistent variations among cultivars. V1 and V2 were the earlier ones both in spring and autumn sowing. Autumn sowing increased seed yield (+18.0%), TSW (+4.1%), number of siliques per plant (+47.2%), contents of α-linolenic, eicosenoic, erucic and eicosadienoic acids, and polyunsaturated to saturated fatty acid ratio. Regarding genotype, V3 showed the best seed and oil yield in autumn, whereas V1 and CELINE were the best performing in spring.

  • Pollination of Two Oilproducing Plant Species: Camelina (Camelina
    GCB Bioenergy (2013), doi: 10.1111/gcbb.12122 Pollination of two oil-producing plant species: Camelina (Camelina sativa L. Crantz) and pennycress (Thlaspi arvense L.) double-cropping in Germany JANNA H. GROENEVELD* andALEXANDRA-MARIA KLEIN*† *Institute of Ecology, Ecosystem Functions, Leuphana University Luneburg,€ Scharnhorststr. 1, Luneburg€ 21335, Germany, †Institute of Earth and Environmental Sciences, Nature Conservation and Landscape Ecology, University of Freiburg, Tennenbacherstr. 4, Freiburg 79106, Germany Abstract Camelina and pennycress are two annual oil-producing plant species that have recently gained attention as bio- fuel feedstock crops. Prior to commercial production, information on their breeding and pollination system is essential to ensure sustainable management. We conducted pollination experiments and observed flower visitors in an experimental double-cropping system in southern Germany. We found that common camelina varieties were mainly self-pollinated and yield of one variety seemed to benefit from insect visitation, whereas penny- cress was predominantly wind pollinated. Camelina showed higher overall visitation rates by insects than pen- nycress. Flies and wild bees visited both crop species, but honey bees visited camelina only. We conclude that both oil crop species produce yield without pollinators but offer foraging resources for different insect taxa at times when few other crops and native plants are flowering.

In vitro assays were used to determine the antioxidant + activity, i.e., ABTS• and DPPH• scavenging activity, the ferric-reducing antioxidant power (FRAP) and the ability to inhibit β-carotene–linoleic acid emulsion oxidation. Phenolic compounds, such as mono- and dicaffeoylquinic acid isomers and caffeic acid hexose, were identified using the LC–TOF–MS/MS technique. The predominant compound during the growth cycle of the plant was 3,5-di-O-caffeoylquinic acid, whose content was the highest at the mid-flowering stage. The total phenolic content was also the highest in sunflowers at the mid-flowering stage. The main phenolic + compound contents were closely correlated with ABTS• and DPPH• scavenging activity and FRAP.

It has more biodiesel potential per unit area of land than many other crops with minimum usage of inputs. This is very useful for effective spring moisture utilization. Biofuels appear to be a potential alternative “greener” energy substitute for fossil fuels. About 84% savings in GHG emissions were obtained with camelina jet fuel, compared with petroleum jet fuel.

  • A Catalogue of the Wild Relatives of Cultivated Plants Native to Europe
    Flora Mediterranea 5 - 1995 375 A Catalogue of the Wild Relatives of Cultivated Plants Native to Europe An enumeration of the wild genetic resources of native European plants that are grown in Europe for food, forage, ornament, timber and other purposes Prepared by Vemon H. Heywood & Daniel Zohary Introduction Europe has a long history of plant domestication and a rich heritage of crops cultivated for a diversity of purposes. The number of plants involved is remarkably high yet much of this heritage has been surprisingly neglected. No systematic account of the crop plants developed in Europe and the genetic resources present in their wild relatives has been produced up to the present. This Catalogue aims to fili that gap. Approximately 10% of the species of the European flora are regarded as being threatened to some degree. Amongst these are wild relatives of numerous cultivated plants, some of which are already facing serious genetic erosion, and in a few cases, a risk of their extinction. The development of new priorities for the conservation of threatened plants is urgently needed in Europe. In these priorities, some of the plants Iisted here should figure prominently if the continent is not to lose much of the wild genetic basis of economie plants which have had their origins here. This Catalogue provides a survey of the wild genetic resources of cultivated plants in Europe as circumscribed by Flora Europaea (Tutin, Heywood et al. 1964-1980, Tutin et al. 1993). (See also Fig. I). In addition, Cyprus and the Canary Islands are also included because they are member states (or part of a member state) of the Council of Europe.
