Abstract: This paper deals with quality character,safe and equilibrium moisture content equilibrium moisture content,light-inhibited germination and five storage methods of Kandelia candel hypocotyl.The results showed that process of water losing of the hypocotyl was fast,slow and fast;When moisture content reduced to 35.1%,all of the hypocotyls would lose their viability.The critical safe moisture content was 51.2%,It would be favourable for hypocotyl storage when the moisture content of hypocotyl could be controlled within 55.2%～58.3%.he lower temperature(5～8℃)storage method was the best one,by which the survival rate of hypocotyl could reach 83.3% after stored for six months,the sawdust storage was the second,by which the survive rate of hypocotyl was 70% after stored for 105 days;immersed-in-sea water,buried-in-sand and natural dry storage methods were only suitable for temporary storage(within 15 days)of collected hypocotyls.
