Planting tropical trees is often hampered by the difficulty of obtaining enough good seed of the right species. After describing the process of sexual reproduction in trees, this manual first looks at the possibilities for stimulating flower formation and for increasing the setting of fruits. It provides all the information necessary to choose the best sources for seeds, and to select the best seeds for a particular planting site. Practical instructions are given on how best to germinate the seeds, and how to nurture and care for the young seedlings.
