Ballistic accretion on seeds of different sizes
Physical Review A, 1991Computer simulations of ballistic driven accretions on seeds of different sizes were carried out. The results, in agreement with previous work reported for the general case of seeds of particle size, show that the kinematics of accretion does not depend on the size of the seed.

Heritability of Seed Shape and Seed Size in Soybean
Crop Science, 1997Round seeds are desirable for food‐type soybean [Glycine max (L.) Merr.] cultivars and an understanding of the heritability of seed shape would benefit the development of these cultivars. The objectives of this study were to estimate heritability of seed shape and seed size by parent‐offspring regression, parent‐offspring correlation, and realized ...

Elevational gradients are a powerful tool to investigate how abiotic factors affect ecosystems and to predict the possible consequences of climate change. Here, we investigated the assemblage-level responses of seed size, ant worker size, and rates of seed removal by ants along a 1700 m elevational gradient in Mediterranean grasslands of central Spain,

Influence of Seed Size on Seed Quality of Sorghum
Madras Agricultural Journal, 1980Five seed size classes of sorghum CSH 5 hybrid and its parents, CS 3541, ms 2077 A and 2077 8 were studied for the relative differences in seed quality. The 1000-seed weight, seed volume and specific gravity of seeds showed distinct and significant differences among seed sizes. The germination and field emergence potential of 10, 9 and 8 retained seeds

DETERMINING SEED SIZE BY A VOLUMETRIC MEASURE
Canadian Journal of Research, 1948A method for determining seed size of flax by a volumetric measurement was devised as an alternative to weighing the seed. The volumetric or 'displacement' measurement can be expressed by means of a factor, in terms of 1000 kernel weight in grams. The 'displacement' method is more rapid than weighing the seed.

The paradox of seed size and adaptation
Trends in Ecology & Evolution, 1989Correlations between habitat and seed size suggest that this character is adaptive. Mean seed size is a relatively invariant species characteristic and seed size has marked effects upon fitness. These observations have previously led to the conclusion that seed size is under stabilizing selection.

Predation, seed size partitioning and the evolution of body size in seed-eating finches
Evolutionary Ecology, 1991I compare the relationship between bill size (depth) and body size among different taxa of seed-eating finches to test the hypothesis (Schluter, 1988a) that in habitats where seed-eating finches are vulnerable to predators, finches have larger bodies relative to their bill size.

Evolutionary comparative methods taking into account the potential effects of relatedness reveal that, among 202 species of animal-dispersed tropical woody angiosperms from Peru, large seeds may be an adaptation to: (1) dispersal by mammals rather than by birds and (2) greater plant height.

Seed size and dispersal mode select mast seeding in perennial plants
Integrative ZoologyAbstractReproduction by perennial plants varies from being relatively constant over years to the production of massive and synchronous seed crops at irregular intervals, a reproductive strategy called mast seeding. The sources of interspecific differences in the extent of interannual variation in seed production are largely unknown.
