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

Storage behavior of this species is orthodox; dry to 15-20% eRH and store at -20\u00b0C.<\/p>\n

\u00a0<\/strong><\/p>\n

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

The seeds have dormancy and this dormant related to seed coat (external dormancy) and inhibition materials in the seeds (physiology dormancy).To remove of seed coat (Scarification) can be used different methods (Sandpaper, Sulfuric Acid, Hot water, etc.). To remove physical dormancy (Stratification), Pre-Chilling (for 14 days), Ultrasonic Waves and Hormones (Gibberellic acid 100ppm) are affect. The best methods for remove seed coat and physical dormancy are sandpaper and pre-chilling (14 days at 4\u00b0C) respectively. Then germinate under a constant temperature of 25\u00baC or with an alternating temperature regime of 15\/20\u00baC (with an 8\/16hr photoperiod).<\/p>\n
