Tuuleviljastumisel

Tuuleviljastumisel refers to the process of pollination mediated by wind. It is a common mode of reproduction in many plant species, particularly those that grow in open environments such as grasslands, deserts, and forests where wind currents are prevalent. Plants that rely on wind pollination, also known as anemophily, typically possess specific characteristics to facilitate this process.

These characteristics often include the production of vast quantities of lightweight, dry pollen grains that can be easily carried by the wind over long distances. The pollen grains are usually smooth and lack the sticky or spiny surfaces found in insect-pollinated plants. Flowers adapted for wind pollination are often inconspicuous, lacking bright colors, strong scents, or nectar, as these attractants are unnecessary when wind is the pollinator. Instead, they may have exposed stamens that readily release pollen and large, feathery stigmas that efficiently capture airborne pollen. Grasses, sedges, rushes, and many tree species like oaks, pines, and birches are well-known examples of plants that utilize wind for pollination. The effectiveness of tuuleviljastumisel is highly dependent on wind speed, direction, and atmospheric conditions.
