Germinability

With germination ability of is called plant seed , a seedling form. A seed that cannot sprout is commonly referred to as deaf.

Usually, the ability to germinate and the vigor (the energy inherent in the seedling to pierce the crumb) are tested with a larger amount of plant seeds under defined conditions. The laboratory methods used are defined by the International Seed Testing Association and are valid worldwide. The germination capacity and the vigor is given in% of the seeds that have formed a seedling and referred to as the germination percentage . A minimum germination capacity for seeds that come on the market is stipulated in the Seed Traffic Act and is generally over 90% for useful plants . In the case of forest seeds, however, the germ percentage is often lower. European beeches only achieve a value of around 45%.
