Abstract/Summary

Seeds of Avicennia alba BI. matured at high moisture content and were sensitive to desiccation: no seeds survived desiccation below 35% moisture content. The effect on survival of a factorial combination of five moist storage treatments (fresh seeds in a polyethylene bag, open with water sprayed over regularly, mixed with sand at 10% moisture content, mixed with moist paddy hulls, or naked seeds mixed with sand at 10% moisture content) and three temperatures (28-30degreesC, 17degreesC and 8-10degreesC) was investigated. In addition, seeds were mixed with sand at 5% moisture content and stored at 17degreesC in order to determine the effect of sand moisture content on seed moisture content and viability during storage. Avicennia alba showed recalcitrant seed storage behaviour, but 75% of the seeds remained viable after four months' moist (45-47% moisture content) storage in 10% moisture content sand at 17degreesC.
