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

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

\u00a0<\/em><\/p>\n

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

The seeds of this species are dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks to two month\u200c at 4 \u00baC to germinate uniformly. Then germinate under an alternating temperatures of 20 \u00baC (16 hours of light) and 15 \u00baC (8 hours of darkness).<\/p>\n
