Abstract

The reproductive systems of forest trees that have evolved in wild habitats are usually characterized by delayed flowering age, cyclic seed years, and possibly an optimum, rather than a maximum, number of seeds per tree. Presumably these characteristics are favored by natural selection, though not necessarily in all species or in all situations.
