The first fossil evidence of a pine cone sprouting seeds has been preserved in 40 million-year-old amber. Seed germination typically occurs in the ground after a seed has fallen, but several ...

Precocious germination in pine cones is so rare that only one naturally occurring example of this condition, from 1965, has been described in the scientific literature, Poinar said.

“Next, we hope to take a closer look at whether this is a widespread phenomenon,” says Cannon. Generally speaking, hurricanes can create good conditions for pine seed germination.

Pine seeds that will be stored (cached) for later use need to be handled with care. Exposure to oxygen can be detrimental to the pine seed, affecting its germination rate.
