Studies were undertaken to explore the storage behaviour of Jaman(Syzygium cuminii L. Skeels) seeds. Seeds were dried down to different moisturelevels. Mean germination percentage was the highest (99.1%) at ambient moisturecontent (60%). Reduction in seed moisture content showed significant loss inviability depicting recalcitrant storage behaviour. Seed germination speed washigh (11.51) at 60% moisture but was adversely affected when dried to 18%. Timeto get 50% germination was also significantly increased (18 days for 30% moisturecompared to 7.4 days for control) with the passage of desiccation period. Maximumelectrical conductivity (1010 mu Scm-1) was recorded at low moisture level (18%)which resulted in considerable reduction in seed viability and germination speed.These studies revealed that Jaman seeds are sensitive to desiccation toleranceand their storage behaviour may be recalcitrant.
