Seed Storage <\/strong><\/p>\n

The storage behavior of this species is orthodox (desiccation-tolerant seeds), dry to 15 to 20% eRH, and store at -20\u00b0C.<\/p>\n

Germination<\/strong> requirements<\/strong><\/p>\n

The seeds of this species are not dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks at 4 \u00baC to germinate uniformly. Then germinate under an alternating temperature regime of 15\/20 \u00baC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).<\/p>\n
