Why do female pine cones remain on tree after pollination?
Unlike other gymnosperms, in which pollination, fertilization, and seed maturation occur within the same year, the pines have an extended reproductive cycle of 14-20 months. (The period elapsed between the appearance of the ovulate cone and the maturation of pine seeds in those cones. Fertilization takes place about 1 year after pollination, and seed maturation takes several additional months). Some seeds are shed as soon as they mature, whereas others remain within the female cones for weeks, months, or even years before being shed.
