What is a pollination vector?

Pollination vectors are simply the processes by which pollen is transferred from flower to flower. The two main vectors include
abiotic vectors and biotic vectors.

pollinationAbiotic Vectors
Abiotic vectors of pollination
These are the non-living processes of pollen movement. It includes the actions of wind and water. For example, wind may blow pollen from one flower to the other. Flowers that depend on abiotic vectors do not produce the attractions (bright petals, smells and nectar) as in the case of abiotic vectors. Instead, they produce a lot more pollen. Such plants are not common in rain forests, as there is little wind action to move pollen around. In addition to this, the high density of vegetation means that it is unlikely that a pollen will fall on a mature stigma.

Anemophily is the scientific term for the transportation of pollen by wind. In anemophily, there is a lot of pollen grain waste.

Did you know:
Plants that are pollinated by wind action have some adaptations:
1. The anthers are well exposed so that the wind can blow them
2. The stigmas are larger and hairy to make them trap airbone pollen
3. They produce more lighter, dry and non-sticky pollen
4. Examples are willow tree, ragwed and some grasses such as wheat.

pollinationBiotic Vectors
Biotic vectors of pollination
These are the living processes of pollen movement. As we have already seen, birds, insects and other animals are able to move pollen from flower to flower. Common biotic vectors include butterflies, bees, bats and beetles. Plants that depend on biotic vectors often produce flowers with strong smells, bright colours and nectar. Pollen grains from such plants tend to be sticky.

Humans can help plants pollinate too. Sometimes, crop researchers can collect pollen from high yeilding plants and cross pollinate them with stigmas of other plants.

It is important to note that flowers are adapted to specific kinds of vectors. For example, birds will be attracted to flowers with strong perch and support.
