Abstract
Dendrobium primulinum is an important epiphytic orchid. A successful protocol for mass multiplication and early in vitro flowering was developed. Immature embryos of 4 week after pollination exhibited about 96% germination within 30 days of culture on MS medium containing sucrose (3%) (w/v), NAA and BA (6 and 9 μM) in combination. Protocorm-like bodies (PLBs) formed from the germinating seeds on the germination medium. Rooted plantlets were formed within 2-3 wk on MS medium containing sucrose (3%), NAA and BA (3 and 12 μM in combination) where about 29 shoot/buds produced per cycle of 4 wk interval. The well rooted plantlets produced 4-5 floral buds per spike when they were maintained on MS medium containing sucrose (3%), fresh apple juice (10%) (v/v) for four wk followed by on MS medium freed of apple juice but enriched with NAA and BA (3 and 12 μM respectively). The hardened plantlets were transferred to community potting mix where the about 80% transplants survived after two months of transfer.
