| Pinecones on a burned tree. Some tree species delay seed fall because their cones are dependent on a brief blast of heat to release seed. This dependency on heat during the seed production cycle is called serotiny and becomes a heat trigger for seed drop that may take decades to occur. In environments where hot, fast-moving fires are frequent, some pine species have developed thick, hard cones that are literally glued shut with a strong resin. These âserotinousâ cones can hang on a pine tree for years, long after the enclosed seeds mature. |
