Pinhão manso (Jotropha curcas Linn.) ia a native plant from South America, probably from Brazil, of great economical potential, since its seeds contain 40-50% of oil rich in saturated reduced hydrocarbon, that can be extracted and converted in compounds similar to those produced from petroleum; and show interesting properties for the ndustry of pharmacy and paint. Contributes for the environmental conservancy, since is a renewable biomass, sequestering CO2 from atmosphere, producing fuel oil, replacing mineral diesel, all of this linked to the capacity of protect the soil against erosion and leaching of nutrients. The scientific literature is rare about the economical viability of extraction and utilization of oil, as well as originated from in vitro cultivation. The aim is to compare the conditions of greenhouse and laboratory related to time (conventional production system), versus the effect of hormones AIB and ANA, and seed depth. The multiplication in vi vitro. This research can result in the optimization of the multiplication system in large scale and faster. And if the in vitro cultivation results in the best option, the seedlings will have other benefits such as cleaning endo phytopatogens and uniformity unde the genetical point of view.
