Wind Pollination
Normal wind conditions (lines), pollen transportation and deposition (dots) in a forest and a lake. Thin
lines: horizontal wind and turbulence; heavy lines: resultant updraft
Wind pollination, or anemophily, is the random
dispersal of pollen in the atmosphere using wind currents. Plants using this
mechanism will produce a great quantity of grains due to the chance factor
involved in the meeting of the two gametophytes. A small fraction of this
pollen will settle on the stigmata of other plants, but the bulk of it will be
lost in lakes and bogs. Therefore, pollen of anemophilous species will be well
represented in the fossil record. For this reason, palynologists find this type
of pollen more useful to make paleoenvironment reconstructions and other
studies, as shall be discussed in the next section.
