Axillary buds of Japanese white birch (Betula platyphylla SKATCHEV var. japonica HARA) were encapsulated in sodium alginate to produce individual beads. Using a systematic screening to determine what was necessary for regeneration of plantlets from the beads, we showed that the presence of a large concentration of sucrose in alginate matrix was essential. Most of the encapsulated buds regenerated complete plantlets under aseptic conditions. The beads could be stored at 4°C for at least 40 days without loss of viability.
