Question

Optimum germination conditions differ between species. Sometimes this depends on the evolutionary history of the plant species. One species has higher germination rates when the seeds are exposed to soil with ash present. This is an example of _______________.

Answer 1

seed dormancy

Step-by-step explanation:

Seed dormancy represents an evolutionary adaptation capable of preventing seed germination. Seed dormancy enables to overcome unfavorable periods for germination, thus being critical for plant survival. In this regard, it has been shown that in plants living in fire-prone ecosystems (such as, for example, montane forest species), seed germination may be triggered by ash after fire, which is required to break seed dormancy.
