Effect of Hormonal Treatment on Propagation of Jatropha curcus

Study on vegetative propagation in Jatropha curcas clearly indicates the response of different treatments in relation to different characters under observation. IBA treatments of concentration 50 and 75 ppm (24 hour dip) was found reasonably good for getting higher rooting percent, good survival of rooted plants and more vigour than other treatments. In terms of rooting response and survival of rooted plants, IBA treatment with 1000ppm and 1500 ppm concentration (5 minutes dip) performed better over other treatments. Lack of well developed rotting system in higher concentration of IBA through exogenous application seems that it has raised the IBA content to supra optimal level causing considerable reduction in rooting. In the absence of growth regulators, distilled water treatment can serve the purpose of cloning to some extent in this species.
