Since even non-serotinous cones and woody fruits can provide protection from the heat of fire, [6] [7] the key adaptation of fire-induced serotiny is seed storage in a canopy seed bank, which can be released by fire. [8] The fire-release mechanism is commonly a resin that seals the fruit or cone scales shut, but which melts when heated.
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 ...

Their serotinous pine cones open only after having been heated by a fire. [7] [33] The prevalence of forest fire allows the pitch pines to dominate over oaks, which by comparison are usually killed outright by a moderate or intense fire. High air temperatures and dry plant undergrowth contribute to the intensity of the fire.

This pine often forms pure stands on sandy or rocky soil. Many populations are adapted to stand-replacing fires, with the cones remaining closed for many years, until a forest fire kills the mature trees and opens the cones, reseeding the burnt ground. Other populations have not been shaped by regular stand-replacing fires and have reduced ...
