A nursery trial was conducted at National Forest Seed Centre, Seed Orchard Division, Bangladesh Forest Research Institute, Chittagong to evaluate the effect of storage condition and duration on germination of Agar seed. Agar seed were stored at five different storage condition viz. open air (control), sand, chalk powder, normal refrigerator (0-40C) and saw dust for different storage durations viz. 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 and 36 days. Storage condition, duration and their interaction were found significant on germination of Agar seed. Refrigerator (0~40C) showed the highest germination (82%) at 3 days duration. It also prolonged the seed viability (12%) up to 33 days. Such technique of maintaining viability of Agar seed may be useful for raising seedlings and plantations at large scale.
