Mango Glossary

Pollination is the transfer of pollen to a flower's receptive stigma. Mango panicles bear male flowers and bisexual flowers, and insects such as flies and bees can help move pollen between them. A mango can often set fruit without a second cultivar, but pollination is only one step: fertilization, weather, disease, and the tree's resources also influence retention. Protect useful flower visitors and avoid interpreting every fallen flower as evidence that the tree needs a pollination partner.

Self-compatibility is the ability of a plant's own pollen, or pollen from the same genotype, to contribute to successful fertilization. Many mango cultivars can set fruit without a different cultivar nearby, but actual cropping also depends on flower health, weather, pollinators, and tree condition. It is not a guarantee that every solitary tree will crop heavily. A second tree cannot correct poor drainage, damaged flowers, or an unsuitable climate merely by being present in the same yard.

The stigma is the receptive surface of a flower's female reproductive structure where pollen can land and begin the process leading to fertilization. In a mango's bisexual flower, its condition and receptivity are part of successful reproduction. Seeing pollen on a flower does not prove that a compatible pollen tube has reached an ovule. The term is useful when understanding pollination, but ordinary growers usually gain more from protecting flower health and insect visitors than from attempting to inspect every tiny stigma.

A zygotic seedling develops from an embryo formed through fertilization of an egg by pollen. It combines genetic contributions from the parents and can differ from the mother tree even after self-pollination. Mango seeds may produce such a seedling, while polyembryonic seeds can also contain nucellar embryos arising from maternal tissue. The distinction matters for breeding and identity: a seedling grown from a named mango cannot automatically be sold or recorded as that same cultivar.
