AbstractResearches the factors responsible for size hierarchies in individuals of Viola sororia. In V. sororia, survival and reproduction are dependent on size. This study investigates whether the differences in size are due to environment or genetics. Laboratory experiments show that there is some genetic variance explaining percent germination, speed of germination, and some morphological characters but not for growth rate. Additional experiments showed that competition and environment contribute substantially to plant size and growth rate. The author concludes that environment is more important than genetics in determining plant size under natural conditions.
