Environmental Risk Assessment

Summary: Recent findings indicate that double- or relay-cropping winter camelina with forage or food crops can increase yield per area, improve energy balance, and provide several ecosystem services. Double-cropping can help balance food and energy production. The objective of this study was to determine the environmental impact of double- and relay-cropping systems as compared with monocultured maize and soybean in ...

Summary: Objectives of this study were to 1) quantitatively assess the invasion potential of C. sativa by collecting demographic data over two years and developing a population dynamics model, 2) compare experimental results and modeling outcomes to predictions suggested by a qualitative weed risk assessment system, and 3) assess the impact of growing conditions on the relative competitiveness of C. ...

Summary: Standard laboratory-based toxicity experiments were conducted for two alternative fuels, jet fuel derived from Camelina sativa  seeds (HRJ5) and diesel fuel derived from algae (HRD76), and two conventional counterparts, jet fuel (JP5) and ship diesel (F76). Initial toxicity tests performed on water-accommodated fractions (WAF) from neat fuels partitioned into seawater, using four standard marine species in acute and chronic/sublethal ...

Summary: While camelina has high fecundity and large seed losses at harvest, it has limited seed bank persistence and is unlikely to become a weed of agricultural areas. Link: https://www.crops.org/publications/cs/abstracts/53/5/2176

Summary: Outcrossing rates in camelina were low (0.09-0.28%), suggesting camelina is a primarily self-pollinated species. Outcrossing was affected by flowering synchrony influenced by planting date as well as direction and distance (20, 40 or 60 cm) from the pollen source. Pollen-mediated intra-specific gene flow is unlikely to prohibit the development of camelina as a bio-industrial platform. Short distance outcrossing results ...

Summary: The potential for gene flow between Camelina and its wild North American relatives C. alyssum, C. microcarpa and C. rumelica subsp. rumelica, was investigated. The study provided evidence that should the species have sympatric distributions and overlapping flowering periods, gene flow between C. sativa and its wild North American relatives is possible and that it would most likely occur ...

Summary: Although camelina does not crossfertilize Brassica crop species, such as oilseed rape, nothing was known about its ability to cross with other members of the tribe Camelineae, which in addition to arabidopsis includes the widespread weed, shepherd’s purse (Capsella bursa-pastoris). We have tested the ability of camelina to cross with arabidopsis and C. bursa-pastoris, as well as with the ...

Summary: This paper summarizes biological information on three cruciferous weed species: Camelina alyssum, C. microcarpa and C. sativa. Camelina sativa has attracted renewed interest as an oil crop, because of an adaptation to various climatic conditions, low nutrient requirements and resistance to disease and pests. In Europe, where it is now widely grown, it has shown considerable potential in the ...
