Propagation Processing/Propagule Characteristics:
Seeds exhibit physiological dormancy.

Pre-Planting Propagule Treatments:
Seeds are placed in cold moist stratification for 6 to 12 days. Germination occurs at 20D/10N C alternating temperature cycle.
In another study, seeds placed in cold stratification germinated at 25/15 alternating temperature cycle.
