Although seed propagation is sometimes practised, to ensure superior traits of the parent trees it is necessary to prefer asexual propagation which can be achieved by cuttings, layering, budding and grafting. Budding and grafting are most popular. Seeds quickly lose their viability, and hence should be sown soon after extraction from the fruit. Soaking of the seed in water for about 8hr or removing the seed coat and a thin slice at top and bottom may accelerate germination. Seeds are planted in nursery at a spacing of 30cm × 60cm and then transplanted to polybags when they have put forth 4–5 leaves. When seedlings reach 80–90cm in height, they can be transplanted to their permanent location.
Generally, vigorously growing seedlings irrespective of source are used as rootstocks. However, cultivars have also been recognized with specific objectives for using as rootstocks. For example, Duke seedlings are resistant to root rot and cold hardiness and Pollock stock can overcome salinity problem. Similarly, Green and Purple also do well as rootstocks. Green imparts more vigour to the scion than Purple. Side, veneer, cleft grafting or shield budding on 30–40 cm tall, robust, succulent seedlings is generally practised. Trees on rootstocks produced by clonal propagation usually bear fruits early and more uniform than trees grafted on seedling rootstocks.
