Abstract
In vitro plantlets were obtained by culture of isolated embryos of jackfruit in media with activated charcoal. Meristernoids were obtained on the leaf explants from the plantlets. Long-term callus cultures could be established from the stem segments in media with 2,4-D (4 mg/1), NAA (1 mg/1) and coconut milk (15%). The stem callus showed rhizogenesis and the lower part of the roots was coloured orange-red.
Keywords: Artocarpus heterophyllus, callus,, pigments.
