Answer:
Three basic reproductive cycles have been described for temperate-zone conifers.Pollination occurs in the spring or early summer of the second year and fertilization takes place a few weeks later. After fertilization, development of the embryo and seeds is continuous and rapid, with seeds released as early as late summer of the year of pollination.
