Seed Storage
The storage behavior of this species is orthodox (desiccation-tolerant seeds); dry to 15-20% eRH and store at -20°C.
Germination requirements
The seeds of this species have non-deep dormancy. Sterilize seeds before placing them on wet germination paper. Place seeds 14 days in 4ºC for breaking dormancy. Then germinate under an alternating temperature regime of 15/20 ºC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).
