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 ]
Most wind-pollinated plants do not produce nectar, attractive scents, or petals because they are not adapted to pollination by animal vectors. Grasses are a large wind-pollinated group; their stigmas are often feathery to help catch pollen in the wind.
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar ; they may also ...
Chiropterophily or bat pollination is the pollination of flowering plants by bats. Plants adapted to use bats or moths as pollinators typically have white petals, strong scent and flower at night, whereas plants that use birds as pollinators tend to produce copious nectar and have red petals. [25]
Wind-pollinated flowers often have small, dull petals and produce little or no scent. Some of these flowers will often have no petals at all. Flowers that depend on wind pollination will produce large amounts of pollen because most of the pollen scattered by the wind tends to not reach other flowers. [15]
Ash flowers are wind-pollinated and lack petals and sepals. Structurally, the flowers may be bisexual, consisting of two stamens and an ovary, or may be male (staminate), lacking a functional ovary, or female (carpellate), lacking functional stamens. Different forms may occur on the same tree, or on different trees. [8]
Generally flowers that are white or green tend to be wind pollinated; where being a bright color isn't necessary. [2] A common phenotype of UV coloration is the “bulls-eye” pattern where a flower reflects UV light at the ends of the petals and absorbs UV light in the center. [4] This acts as a guide for pollinators to locate and find pollen ...
Traits of the staminate flowers and inflorescences are adapted to wind pollination- either by pendulous spikes, which can be moved by the wind to shed the pollen or by the special adaptation of detachment of anthers, and their secondary attachment allowing the shedding of pollen by motion of anthers.
