Not AvailableComparison of morphogenetic potential of three important Indian species of Garcinia—G. indica, G. cambogia and G. xanthochymus has been reported. Apomictic seeds of G. indica were found to be morphogenetically most potential followed by G. cambogia. The explants of G. xanthochymus were highly recalcitrant towards in vitro conditions and failed to induce adventitious buds on any of the media tested. High frequency direct shoot bud differentiation was induced in aseptic seed cultures of G. indica and G. cambogia on MS medium supplemented with cytokinins (BAP, kinetin or TDZ). Amongst the three cytokinins tested, TDZ (0.1–0.5 μM) was most effective for adventitious bud differentiation in both G. indica and G. cambogia, however, the proliferating buds failed to elongate. Substantial number of buds induced on BAP supplemented media elongated into shoots after subculture on elongation medium. Addition of NAA along with cytokinins in the induction medium enhanced callusing without improvement in bud induction response. The induced adventitious buds were elongated on MS basal medium containing 0.2% activated charcoal. Direct rooting was achieved in both G. indica and G. cambogia on auxin supplemented media with best response at 10 μM IBA concentration in both the species. The in vitro raised plantlets showed 90% survival in the field when transferred after hardening and acclimatization.Not Availabl
