Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. [1] Almost all gymnosperms are anemophilous, as are many plants in the order Poales , including grasses , sedges , and rushes . [ 1 ]
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.
Pollination systems in monocots are just as diverse as in dicots. [1] About two thirds of monocots evolved to be zoophilous (animal pollinated). [1] Others are instead water-pollinated or wind-pollinated such as Cyperaceae, Juncaceae, Sparganiaceae, Typhaceae, and most notably Poaceae. [16]
Wind-pollinated flowers may be small and inconspicuous, as well as green and not showy. They produce enormous numbers of relatively small pollen grains (hence wind-pollinated plants may be allergens, but seldom are animal-pollinated plants allergenic). Their stigmas may be large and feathery to catch the pollen grains.
In leptosporangiate ferns, the fern catapults its spores 1-2 cm so they can be picked up by a second dispersal vector, often the wind. [4]Autochory is the dispersal of diaspores, which are dispersal units consisting of seeds or spores, using only the energy provided by the diaspore or the parent plant. [5]
These plant-animal relationships are often mutually beneficial because of the food source provided in exchange for pollination. Pollination is defined as the transfer of pollen from the anther to the stigma. [2] There are many vectors for pollination, including abiotic (wind and water) and biotic (animal). There are benefits and costs ...
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 ...
Wind pollination is the reproductive strategy adopted by the grasses, sedges, rushes and catkin-bearing plants. Other flowering plants are mostly pollinated by insects (or birds or bats), which seems to be the primitive state, and some plants have secondarily developed wind pollination.
