Cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant. The main characteristics which facilitate cross-pollination are: Herkogamy : Flowers possess some mechanical barrier on their stigmatic surface to avoid self-pollination, e.g. presence of gynostegium and pollinia ...
The MN55 cultivar apple developed by David Bedford, a senior researcher and research pomologist at the University of Minnesota's apple-breeding program, and James Luby, PhD, professor, Department of Horticultural Sciences, Horticultural Research Center, is a cross between Honeycrisp and MonArk (AA44), a non-patented apple variety grown in Arkansas.
Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate. [1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years.

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 ...
For instance, hand-pollination is used with date palms to avoid wasting space and energy growing sufficient male plants for adequate natural pollination. Because of the level of labor involved, hand-pollination is only an option on a small scale, used chiefly by small market gardeners and owners of individual plants.
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...

Chasmogamy is the type of plant reproduction in which the flowers open up, enabling cross-pollination. This is in contrast to cleistogamy , in which the flowers stay closed and self-pollinate . Chasmogamous flowers are commonly showy with open petals encircling exposed reproductive parts.
