PEDRAZA SANCHEZ, Erik Alexander  e  CAYON SALINAS, Daniel Gerardo. Morphophysiological characterization of Jatropha curcas L. variety Brazil in two areas of Colombia. Acta Agron. [online]. 2010, vol.59, n.1, pp.30-36. ISSN 0120-2812.

Piñón or Jatrofa (Jatropha curcas L.) is an oleaginous plant that has gained importance in Colombia for their high production and quality of oil for biofuels, it has attracted interest by the investigation of its physiology and production performance. The study was conducted in two production areas (Vichada and Santander), determining plant height, stem number, leaf area, leaf dry weight, specific leaf area, specific leaf weight, percentage of oil extraction and solvent the fatty acid profile of oil by gas chromatography. A complete randomized blocks design, two production areas, three replications and six plants for replication was utilized. The conditions of the production areas influenced the development of the crop growing season, with the lower leaves of the plant showed a greater area in the two areas, the specific leaf area and specific leaf weight also varied in the two areas. The oil content in the seed showed no changes.
