keinopölyttämistä

Keinopölyttäminen, also known as artificial pollination or assisted pollination, refers to the practice of manually transferring pollen from one flower to another to facilitate fertilization and fruit or seed production. This technique is employed when natural pollination is insufficient or impossible due to various factors.

Natural pollination typically relies on wind, water, insects, or other animals to carry pollen. However, in some situations, such as in greenhouses where pollinators are absent, or with certain plant species that have difficulty with natural pollination, keinopölyttäminen becomes necessary. It can also be used to ensure the pollination of specific desirable crosses in plant breeding programs.

The process involves collecting pollen from the male part of a flower (anther) and applying it to the female part of a receptive flower (stigma). This can be done using various tools, such as a small brush, cotton swab, or specialized mechanical devices. For larger-scale operations, methods like blowing air or using vibrating machines to dislodge pollen may be employed.

Keinopölyttäminen is a valuable horticultural and agricultural technique that can significantly improve crop yields and quality, particularly in controlled environments or for specific plant varieties. It allows for greater control over the pollination process, ensuring that fertilization occurs and leading to successful fruit or seed set where it might otherwise fail.
