The seeds should be collected from healthy, mature plants which are prolific producers of fruits with desirable characteristics. Only large seeds are used. Immediately after extraction from the fruit, the seeds are washed in water to remove the slimy coating around the seeds. The horny part of the pericarp is also removed to hasten germination. As a general rule, the seeds are sown immediately without drying because they are recalcitrant (click to read Sexual Propagation: Orthodox vs. Recalcitrant Seeds). If not possible, however, the seeds can be stored in air-tight plastic containers at 20 C to maintain their viability for about 3 months. In sowing, the seeds are laid flat or with their hilum facing downward. Germination should begin within 10 days. It is expected that 80-100% of the seeds will have germinated within 35 to 40 days after sowing.
