Pretreatment: soak the seeds in cool water for 48 hours; or cover the seeds with boiling water, allow them to cool, and soak for 24 hours.
Nursery technique: the pretreated fruits are put in polythene bags with half of the fruit above the soil. The germination commences in 8 to 12 days and takes about 50 days to complete. The use of pregerminated seeds is preferred to save time and ensure uniform germination. The seedlings are sensitive to drought both at the germination stage and subsequently.
