Pollination is the sexual method of reproducing in every plants by the procedure of transferring the pollen grains from the anther come the stigma the the gynoecium and thereby permit the fertilization process. In this process, the spermatophytes or the seeds plants pass their genetic information come its next-generation, just like all other living organisms.

You are watching: What is a difference between self-pollination and cross-pollination?

Christian Konrad Sprengel first identified the procedure of pollination in the 18th century. This is frequently known as an interaction in between pollen vector and a flower. The definition is found in farming and horticulture.

There room two varieties of pollination -:

Self-pollination

Let united state learn an ext in detail around the differences between the two species of pollination.

Difference in between Self-Pollination and also Cross-Pollination


Self-PollinationCross-Pollination
Transfer pollen seed from the anther to the stigma the the very same flower.Transfer pollen seed from the anther to the stigma the a various flower.
This procedure can take ar in the same flower or a various flower of the exact same plant.This procedure can take it place between two flowers present on different plants.
It wake up in the flowers which are genetically identical.It occurs in between flowers which room genetically different.
Few species that exhibition self-pollination – Paphiopedilum parishii, Arabidopsis thalianaFew types that exhibit cross-pollination – apples, daffodils, pumpkins and also grasses
Causes homogenous problems in progenies.Causes heterozygous problem in progenies.
Self-pollination increases genetic uniformity and decreases genetic variation.Cross-pollination decreases hereditary uniformity and also increases hereditary variation.
Causes inbreeding.Causes outbreeding.
Reduces the gene pool.Maintains the gene pool.
Produces limited amounts the pollen grains.Produces big amounts the pollen grains.
In self-pollination, both the stigma and also anther concurrently matureIn cross-pollination, both the stigma and also anther mature at different times.
Transfers a limited number the pollens.Transfers big numbers the pollen.
This process is brought out even when the flowers are closed.For cross-pollination come happen, the flower must be open.
No need for pollinators to move pollen grains.Require pollinators to move pollen grains.
Pollen grains space transferred straight to a flower’s stigma.Pollen seed are lugged via wind, insects, animals, water, etc.
