Popis: 349 Camelina is an ancient crop believed to have evolved as a weed in fi elds planted with fl ax, hence the name “false fl ax” (Budin et al., 1995; Gugel and Falk, 2006). According to Matthaus and Zubr (2000), camelina was cultivated for oil in Europe during the Bronze and Iron Ages; however, its production dwindled during the Middle Ages. Th ere has been recent interest in camelina production because of increased demand for biofuel and other industrial applications from non-edible oilseeds. Several attractive features of camelina make it a potential oilseed crop. It is a low-cost bioenergy crop and the oil has been used successfully as fuel for diesel transport engines (Bernardo et al., 2003). According to Shonnard et al. (2010), when camelina jet fuel was fl ight tested, it met all the requirements for engine performance. In addition, greenhouse gases emitted during combustion of camelina-based fuels were lower than that of petroleum based fuel. Pinzi et al. (2009) indicated that cold weather aff ects the performance of most biofuels; however, fuel derived from camelina is able to withstand lower temperatures because of its high polyunsaturated fatty acid content. Besides biodiesel potential, camelina seeds have an average oil content of 350 to 450 g kg–1, and the proportion of unsaturated fatty acid in the oil is approximately 900 g kg–1 (Gugel and Falk, 2006). Th e high content of unsaturated fatty acid makes camelina oil fastdrying which is useful for making environmentally friendly polymers, varnishes, paints, cosmetics, and dermatological products (Zaleckas et al., 2012). Agronomically, camelina has wide environmental adaptation because it can grow under diff erent climatic and soil conditions (Zubr, 2003). According to Moser and Vaughn (2010), camelina is able to grow well in semiarid regions and in low-fertile and saline soils. Camelina requires low agricultural inputs and its production cost is relatively low (Budin et al., 1995; Moser and Vaughn, 2010).
