Seed size and plant strategy across the whole life cycle

摘要: We compiled information from the international literature to quantify relationships between seed mass and survival through each of hazards plants face production maturity. found that small-seeded species were more abundant in rain than large-seeded species. However, this numerical advantage was lost by seedling emergence. The disadvantage probably results size-selective post-dispersal predation, or longer time spend soil before germination. Seedlings have higher a given amount as seedlings. seems be countered greater taken for reach reproductive maturity: our data suggested no relationship, perhaps weak negative size emergence adulthood. A previous compilation showed inverse relationship number seeds produced per unit canopy area year is positive mass, plant longevity. Taken together, these show old understanding species' result trade-off producing few large offspring, with high probability, versus many small offspring lower chance successfully establishing incomplete. It likely evolves part spectrum life history traits, including size, longevity, juvenile rate reproduction.
