Plants grow and flower as long as there is open space and plenty of light. Fireweed reaches its average peak colonization after five years and then begins to be replaced as trees and brush grow larger. When a new fire or other disturbance occurs that opens up the ground to light again, the seeds germinate.
Fire exclusion has resulted in a declining reproductive output, and thus population size, of some species of pyrogenic plants. [3] Additionally, evidence suggests that fires that occur outside of normal seasonal burn times (typically summer months) can have negative repercussions on pyrogenic flowering plants, including lower flowering and seed production when compared to fire-exposed plants ...
Longleaf pine (Pinus palustris) is a pyrophile, depending on fire to clear the ground for seed germination. [4] The passage of fire, by increasing temperature and releasing smoke, is necessary to raise seeds dormancy of pyrophile plants such as Cistus and Byblis an Australian passive carnivorous plant. Imperata cylindrica is a plant of Papua ...

The karrikins and water can provide a 'wake-up call' for such seeds, triggering germination of the soil seed bank. The plants that depend on karrikins to grow are known as "fire-followers", [1] they emerge grow quickly, flower and produce new seeds, which fall to the ground. These seeds can remain in the soil for decades, until the next fire ...
"Obligate seeders" are plants with large, fire-activated seed banks that germinate, grow, and mature rapidly following a fire, in order to reproduce and renew the seed bank before the next fire. [23] [24] Seeds may contain the receptor protein KAI2, that is activated by the growth hormones karrikin released by the fire. [25] Fire tolerance.
