This is the second edition of a multi-author book first published in 1992. It deals with all aspects of plant regeneration by seeds, including reproductive allocation, seed dispersal and predation, longevity, dormancy and germination. All chapters have been updated, and four new chapters added on seed size, seedling establishment, the role of gaps, and regeneration from seed after fire.
There are two basic physiological prerequisites for seeds to survive in soil: germination must be avoided by dormancy or quiescence, while viability must be maintained. The remarkable longevity of some individual seeds is legendary. This chapter reviews some of these accounts, assessing these long-lived individuals in the context of the overall seed population.
