Seed germination and optimum time of transfer of seedlings of Calamus spp. from seed bed to polyethylene bag were studied. Seeds of C. latifolius Roxb. (Bhudum-bet) and C. guruba Buch.-Ham. (Jali-bet) sown under higher temperature (27-35oC) and humidity (90-95%) showed 42 and 71% germination within 12-13 weeks and 4-9 weeks respectively. Germination of C. latifolius seeds increased on removing the scaly epicarp and fleshy sarcotesta manually with ash. Seedlings of C. guruba of one to five weeks age when transferred from seed bed to polyethylene bag, showed significantly higher height growth up to five months compared to those transferred sub-sequently.
