Rooting ability in IBA induced stem cuttings in vegetative regeneration experiments largely depends on various parameters, which has been established using SVI (sprouting value index), a mathematical approach. Marathi-moggu the Bombax ceiba tree is a medicinal and avenue tree species of tropical India that has known to have poor regeneration through seeds and hence in the present study stem cuttings of saplings were used to generate clonal plant propagules. Field studies were carried out using three rooting medium at a location in Central Kerala, Peninsular India, for one year at four months regular interval. Three IBA (Indole 3- butyric acid) concentrations 300 ppm, 500 ppm and 1000 ppm IBA, have been used and the data obtained was evaluated with SVI (sprouting value index) method in order to evaluate the suitable medium, which gives maximum results. The control cuttings do not recorded rooting. The results obtained indicate high SVI (sprouting value index), when stem root cuttings planted in root trainers with coir pith compost (RTCP) for all the three concentration of IBA applied. Sprouting percentage was increased and the delay in completion of sprouting/rooting initiation decreased by the use of IBA treatment.
