anemophily

(redirected from Wind pollination)

anemophily

the transfer of pollen from male to female plant organs by means of the wind. The process usually involves cross-pollination between different plants, rather than self-pollination (see POLLINATION). Wind pollination is very wasteful of male gemetes and is fairly rare in ANGIOSPERMS (most having evolved other, more efficient methods in partnership with insects), but common in GYMNOSPERMS such as pines.

Well-known angiosperm anemophilous plants include the grasses (a group containing cereals such as maize, wheat and barley), stinging nettles, docks and plantains.

Various features of anemophily can be recognized in angiosperms: flowers small and inconspicuous, often green with reduced petals; flowers with no nectar or perfume; stamens often long and pendulous (e.g. hazel catkins) or projecting up above the herbaceous plant (e.g. plantain, docks) to ensure efficient pollen dispersal; flowers frequently appear early in spring before leaves can interfere with pollination; stigmata are often branched and feathery to catch the airborne pollen. Compare ENTOMOPHILY.

Wind pollination is normal in plants with tassels such as pecans, casuarinas and sweetcorn, to name just a few.
For wind pollination to be successful, the plants must produce lots more pollen.
For this purpose, this article is organized into three main sections: (1) a brief review of some basic aerodynamic concepts pertaining to wind pollination, (2) a consideration of the functional traits of most anemophilous species, and (3) a re-evaluation of the data previously reported for the two species of Ephedra.
Honey bee workers as well as other insect visitor in the area had access to flowers and wind pollination was also possible.
For wind pollination to work well, several plants must grow close enough together that pollen gets released in drifting clouds.
According to these results, wind pollination had no effect on the number or the weight of seeds per fruit.
The article said wind can "carry pollen for miles" but, unlike insects as pollen carriers, wind pollination is much less effective at carrying pollen more than a short distances from the anthers of the plants that produce it.
The flowers are self-fertile, so wind pollination and insect pollinators are not required for fruit set.
To determine effect of different guilds of vectors of pollen on production of achenes, pollination treatments were applied during the flowering season of each of the four species in 1996: control, with access to all possible mechanisms of pollination (insects, wind, and autonomous self-fertilization); diurnal pollination, with access to diurnal insects (from dawn to sunset), wind, and autonomous self-fertilization; nocturnal pollination, with access to nocturnal insects (from sunset to dawn), wind, and autonomous self-fertilization; wind pollination, preventing access by insects but allowing autonomous self-fertilization; and, autonomous self-fertilization, prohibiting access by both insects and wind.
napus is considered a self-compatible crop (Williams, 1978; Eisikowitch, 1981), susceptible to wind pollination (Gene Technology Regulator, 2002), the foraging bees increase its productivity rate (McGregor, 1976; Delaplane and Mayer, 2000; Sabbahi et al., 2005).
Plant out leeks and celery in rows and plant sweet corn in blocks to ensure good wind pollination. Sow successional rows of salad crops such as rocket, radish and lettuce, using the spaces between the rows of slower growing crops to maximise the use of your plot.
CROPS are mostly populated through bee and wind pollination.
