ABSTRACT: Jatropha platyphylla 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 Jatropha platyphylla 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 Jatropha platyphylla 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. This demonstrates the necessity to improve the
conventional propagation methods with appropriate scientific inputs for
more economical and time efficient techniques for standard propagation
protocols.
