itävyysarvioon

Itävyysarvio is a Finnish term that translates to germination test or germination capacity test. It is a procedure used to determine the percentage of seeds in a sample that are viable and capable of germinating under favorable conditions. This assessment is crucial in agriculture, horticulture, and seed production to ensure the quality and performance of seeds.

The process typically involves placing a specific number of seeds on a suitable germination medium, such as filter paper or a sterile substrate, and then incubating them under controlled environmental conditions, including temperature, moisture, and light. The duration of the test varies depending on the seed species. After the incubation period, the number of seeds that have successfully germinated is counted. Viable seeds are typically identified by the emergence of a healthy radicle and plumule.

The result of an itävyysarvio is usually expressed as a percentage, representing the proportion of germinated seeds out of the total number of seeds tested. A high germination percentage indicates good seed quality, while a low percentage may suggest poor viability due to factors like age, improper storage, disease, or physical damage. This information is vital for farmers and gardeners when deciding on seeding rates and for seed companies to meet quality standards and labeling requirements.
