Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma , either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination , so pollinizer trees are planted in orchards.

The tree produces spiky green fruits about the size of a golf ball, which turn brown and drop off the tree over an extended period beginning in fall and continuing over the winter.
The seeds of many Australian plants and plants from southern Africa and the American west require smoke or fire to germinate. Some plant species, including many trees, do not produce seeds until they reach maturity, which may take many years. Seeds can be difficult to acquire, and some plants do not produce seed at all.
The fruit is a dry egg-shaped capsule 3–4 centimetres (1 + 1 ⁄ 8 – 1 + 5 ⁄ 8 in) long, containing numerous tiny seeds. The seeds are winged and disperse by wind and water. Pollarded trees do not produce flowers, as these form only on mature wood. Paulownia tomentosa requires full sun for proper growth.
Propagation is nearly always by seeds, but the fruit of seedling trees is variable. Fresh seeds need to be planted within a few days if they are to remain viable, and germinate in two to three weeks. The lower branches of the seedling may be pruned after a year, and the first fruit can be expected in three years, with substantial yields at five ...
Plant showing autumn coloring and mature fruit. Nyssa sylvatica is an important food source for many migrating birds in the fall [autumn]. Its early color change (foliar fruit flagging) is thought to attract birds to the available fruit, which ripen before many other fall fruits and berries.
