摘　　要：<i><span style="font-family:"">Jatropha</span></i><span style="font-family:""> <i>platyphylla</i> </span><span style="font-family:"">is considered as a potential source of edible protein, oil, and phenolic compounds with anti-inflammatory activity. The use of stem cutting in vegetative propagation and grafting is as indispensable tools for mass multiplication of superior genotypes and helps in improve planting yield and quality. The study was aimed to investigate the effect of different diameters (10 - 15, 16 - 25 and 26 - 35 mm) and different hormone concentrations of indo-butyric acid (0, 1.5, 3, 6 and 10 g/L), in the rooting of <i>Jatropha</i> <i>platyphylla</i> and to obtain axillary buds to performed grafts. Rooting efficiency was 80% in greenhouse conditions. Hormone concentration and diameter significantly affected the rooting and shooting ability of <i>Jatropha</i> <i>platyphylla</i> stem cuttings. Stem cuttings of 26 - 35 mm have the greatest number, length and dry root weight. 76% survival of the grafted plants was obtained. <span>This demonstrates the necessity to improve the conventional propagation methods</span> with appropriate scientific inputs for more economical and time efficient techniques for standard propagation protocols.<i><span style="font-family:"">Jatropha</span></i><span style="font-family:""> <i>platyphylla</i> </span><span style="font-family:"">is considered as a potential source of edible protein, oil, and phenolic compounds with anti-inflammatory activity.
