Keeping this in mind, an attempt was made to standardize the technique of its vegetative propagation by stem cutting with varying thickness viz. <1cm, 1-1.5cm and >1.5cm. Juvenile and mature stem cuttings of this plant were tested for their rooting and sprouting ability. Cuttings were treated with different concentrations (50, 100, 200, 400, 600, 800 and 1000 ppm) of auxins (IBA and NAA) along with distilled water (control). IBA and NAA at 100ppm showed the best result compared to other treatments. IBA treatment reponsed better as compared to NAA. Supra optimal level of auxins treatment causing reduction in rooting. https://www.biotech-asia.org/vol4no2/vegetative-propagation-in-jatropha-curcas-l/ Jatropha curcas; vegetative propagation; stem cutting Indole-3- butyric acid (IBA)
