Propagation methods for physic nut (Jatropha curcas)

Abstract

Jatropha curcas L. (pinhão-manso) is well adapted to various regions in Brazil with potential for use in hedges, as a medicinal plant, and in biofuel production. Physic nut also has good capacity for revegetating degraded areas. In recent years, many studies have been conducted to improve the cultivation of the species, aiming mainly to supply the market of biodiesel production. However, there is still lack of information about clonal propagation and management of the species, especially with the selection of superior individuals, since most plantations are still performed with seedlings produced from seeds. In this context, this study proposed to identify studies on physic nut considering the propagation and cultivation techniques used for seedling production, aiming at the improvement of commercial plantation species by selecting the appropriate method of establishment. Thus, the method for the production of physic nut seedlings depends on the characteristics of plant material, cultivation environment and the purpose of planting. More studies are required, taking into account plant breeding and multiplication of the species in the management of superior individuals to improve the quality of crops.
