== Propagation ==

* '''Seed''' is the standard method. Seeds are recalcitrant, with no dormancy and a storage life measured in days, so sow them fresh after cleaning. Germination takes 10 to 120 days. Seeds are polyembryonic, meaning that one seed can produce 3 to 8 seedlings, most of them close to the parent type. Surface-sow in shade, firm the seed into the medium, and keep it moist. Young plants transplant poorly, so pot them individually before the roots become crowded.<sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-2|[2]]]</sup>
* '''Air-layering''' is the most useful clonal method. Spring layers treated with 1000 ppm NAA have produced about 60% rooting. Air-layers taken during the rainy season may fail to root. In West Bengal, air-layering is performed in July, with planting out in October and November.<sup>[[#cite_note-1|[1]]]</sup>
* '''Cuttings and grafting''' have produced inconsistent results. Hardwood cuttings did not root even with hormones, while semihardwood cuttings achieved about 20% success. Chip and T-budding were unsuccessful. Veneer grafting of spring-flush scions onto one-year-old rootstocks succeeded in about 31% of plants.<sup>[[#cite_note-1|[1]]]</sup>

In India, vegetative propagation work has focused on selecting and maintaining dwarf types. These selections may be particularly useful for container growers.
