selfpollinators

Self-pollination is a form of pollination in flowering plants where pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant. This process can occur through various agents such as wind, water, or animals, or it can happen internally within the flower structure itself, a process known as autogamy. Self-pollination results in self-fertilization, leading to offspring that are genetically very similar to the parent plant.

Many plants have evolved mechanisms to promote self-pollination. These can include flowers that are hermaphroditic, possessing both male (anthers) and female (pistils) reproductive organs, and having these organs mature at the same time. Some flowers also have structures that facilitate pollen transfer within the flower. While self-pollination can ensure reproduction in the absence of pollinators, it often leads to reduced genetic diversity compared to cross-pollination. This reduced diversity can make self-pollinating populations more vulnerable to environmental changes and diseases. Examples of plants that commonly self-pollinate include peas, beans, and tomatoes. Despite its drawbacks, self-pollination is a successful reproductive strategy for many species, particularly those that are stationary or exist in isolated environments.
