Seed germination ecology of the rare hemiparasite Tomanthera auriculata (Scrophulariaceae)

Cold stratification was required to break seed dormancy, and the optimum thermoperiod for germination of nondormant seeds was 15/6 or 20/10°C. Light was required for germination, and maximum germination percentages were obtained for seed samples that were both cold-stratified and incubated in light. Seeds can remain viable for at least 2.5-3.5 yr. -from Authors
