serotiny (adj. serotinous) In certain plants, especially trees (e.g. jack pine (Pinus banksiana), lodgepole pine (P. contorta), and many species of Eucalyptus), the retention of seeds in pods or cones on the tree, often for many years, until a disaster, most commonly the heat of a fire, causes their release. After fire, the seeds fall on ground fertilized by ash in a site cleared of competitors.
