Seed bank and germination
Maximum germination was observed for G. regularis at the 80 degrees Celsius dry heat shock treatment. Wet heat (boiling water) treatments, however, resulted in 100% mortality of seeds.[1]
Fire ecology
In a field study of vegetation change in Florida scrub, G. regularis cover increased after fire.[2] However, this increase may not be the direct result of fire. Heat shock germination may play a role in its post-fire recruitment.[1] The amount of G. regularis decreased after a spring burn; decreased slightly after a summer burn; and increased in the control plots.[3] A total of 24 plants in four new quadrants were recruited postburn study in the Florida scrub – Lake Wales Ridge area.[4] “Results from previous studies (Cushwa and Redd 1966; Cushwa et al. 1969) indicate that leguminous plants and seed respond best to “hot” f i r e s - - i . e., those in which a high proportion of the ground fuel is consumed. Laboratory tests (Martin and Cushwa 1966; Cushwa et al. 1968) have also shown that seed from several leguminous species germinate best after scarification with moist heat at temperatures near 80” C., a situation requiring a hot fire. The response of the leguminous plants and seed in this study, therefore, would probably have been greater if the pine stands had been burned with more intense fires. Nevertheless, further work will be necessary before we can make final conclusions about the value of prescribed burning to quail and other wildlife in the 2.5 million acres of pine in the South Carolina Piedmont.”
