selvbestøvede

Selvbestøvede, also known as self-pollinated, refers to the process by which a plant pollinates itself without the need for external agents such as insects, wind, or other animals. This type of pollination is common in many plant species, particularly those that are wind-pollinated or self-compatible. In self-pollination, the pollen from the anthers 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 mechanisms, including the movement of pollen grains by the wind, the shaking of the plant, or the physical contact of the flower's parts.

Self-pollination is advantageous for plants in several ways. It ensures genetic diversity within a single plant, as the pollen can come from different parts of the same flower or plant. This can lead to the production of seeds with a wider range of genetic traits. Additionally, self-pollination can be more efficient than cross-pollination, as it does not rely on external factors such as the presence of pollinators or favorable weather conditions.

However, self-pollination also has its limitations. It can lead to inbreeding, which may result in a decrease in genetic diversity over time. This can make a population more susceptible to diseases and environmental changes. To mitigate this, many plants that are capable of self-pollination also have mechanisms to promote cross-pollination when conditions are favorable.

In agriculture, self-pollinated plants are often preferred for their reliability and consistency. They can produce seeds that are true to type, meaning they will grow into plants with the same characteristics as the parent plant. This makes them ideal for breeding and cultivation purposes. Examples of self-pollinated plants include many varieties of corn, wheat, and soybeans.
