Siemenkestävyys

Siemenkestävyys refers to the ability of seeds to survive unfavorable conditions for a certain period. This survival mechanism allows plants to persist through seasons or environmental challenges that would otherwise be lethal. The duration of dormancy, which is a key aspect of siemnkestävyys, varies greatly depending on the plant species and the specific environmental triggers. Some seeds can remain viable for only a few months, while others, under optimal storage conditions, can survive for decades or even centuries.

Factors influencing siemnkestävyys include the seed's genetic makeup, its physical structure, and the presence of inhibitors or promoters of germination. Environmental factors such as temperature, moisture, and light also play crucial roles in maintaining or breaking dormancy. For instance, some seeds require a period of cold stratification to germinate, while others need specific light wavelengths. Understanding siemnkestävyys is vital in agriculture for seed storage and crop management, as well as in ecological studies for understanding plant population dynamics and restoration efforts. Seed banks worldwide aim to preserve biodiversity by storing seeds with long-term viability.
