In this paper we studied in vitro and ex vitroculture techniques for Jatropha curcas L. vegetative propagation. Cloning oflocal varieties of this species will establish the basis fo a domestication programof Jatropha curcas L. in the province of Misiones. Using in vitro culture techniques,it was obtained organgenic tissue induction in different explants growth on MSbasal medium (Murashige and Skoog, 1962) supplemented with BAD, TDZ KIN or incombination with AIB. Significant differences between nutrient media studied inthe differentiation process were not observed, being able to be used MS, MS ½ orMS + CA with a high rate of differentiation. The rooting of apical sectionsobtained, from juvenile and adult stock plants, whose bases were treated with asolution of 70% ethanol for 10 seconds without IBA (TC1) showed, respectively,75 and 45% rooting, significantly higher than the cuttings treated with IBA.Nevertheless, when the apical section cuttings received the treatment control withwater (TC2), they showed significant differences between young and adult cuttings.A significantly higher rooting percentage was obtained when juvenile apicalcuttings were used with no hormone application (TC2) (75±15%).
