Storability and germination of sodium alginate encapsulated somatic embryos of Vigna aconitifolia (Jacq.) cv. BMB-43 were tested on half strength Murashige and Skoog (MS) basal medium fortified with coconut water (10% v/v). The frequency of regeneration from encapsulatd embryos was affected significantly by concentration of sodium alginate and the duration of exposure to calcium chloride. Embryos encapsulated with 2.5 % sodium alginate dissolved in MS basal salts solution recorded significantly higher germination than other treatments. A relatively short (5 min) incubation with calcium chloride solution provided uniform encapsulation of embryos that gave the highest percentage (65%) of germination. Synthetic seeds could be stored at 4üC for 50 days without reduction in viability as opposed to non - encapsulated somatic embryos which showed 6% viability after 20 days at 4°C. Germinated synthetic seeds produced normal plantlets.
