Seed Germination Syndromes in Higher Plants
the stages of a plant’s life history represent critical, distinctive episodes in the ongoing maintenance of genetic continuity for that species. Successful completion of each stage is dependent on the detection of and appropriate response to variation in the physical and biotic environment. Natural selection will shape a unique pattern of environmental sensitivity for each plant species, which is dependent on the past history of that species. Usually, however, a group of species will share a set of correlated life-history responses to characteristic environmental regimes. Such correlated responses have been referred to as a character syndrome (Stebbins, 1970). Insofar as we can define generalized selective regimes in the environment, we should be able to recognize a limited number of character syndromes.
