Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [1] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives ...
Pearl millet seed production plots at ICRISAT (Patancheru, Hyderabad (AP), India), the panicles covered in parchment paper bags to ensure self-pollination. Pollination bags, sometimes called crossing bags, isolation bags or exclusion bags, are containers made of various different materials for the purpose of controlling pollination for plants.
The pollination mechanism of Orchis mascula is given as an example of a mechanism for transferring pollen to insects: the diagram from the book shows all the petals cut away except the lowest petal, the labellum, which extends back to form a tubular nectary below the column.
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.

The plant the pollen is taken from is called the pollen donor or pollen parent, while the plant receiving the pollen is the seed parent. Hand-pollination is often done with a cotton swab or small brush, but can also be done by removing the petals from a male flower and brushing it against the stigmas of female flowers, or by simply shaking ...
The pollination network is bipartite as interactions only exist between two distinct, non-overlapping sets of species, but not within the set: a pollinator can never be pollinated, unlike in a predator-prey network where a predator can be depredated. [2]
