摘要

Albizia saman (Jacq.) F. Muell. commonly known as rain tree seeds were treated with five pre-sowing treatments to study the effect of pre-sowing treatments on germination and initial seedling development in the nursery. The experiment was established in the nursery of the Institute of Forestry and Environmental Sciences, University of Chittagong, Chittagong, Bangladesh. Results revealed that Nail clipping in one side of the seed (at the distal end of the seed) (T_4) provides the highest (50%) seed germination. The second highest germination (42%) was obtained for the seeds treated with immersion in cold water for 24 h (T_1). Germination was completely inhibited when the seeds immersed in boiled water for 30 s followed in cold water soaking for 24 h. Other germination parameter and initial morphological growth and biomass production of the seedlings was also higher for the treatments T_4 and T_1 in comparison to the control (T_0) treatment. Pre-sowing treatments of T_4 e.g. Nail clipping in one side of the seed (at the distal end of the seed) and T_1 (Seeds immersed in cold water for 24 h) may be recommended for maximum germination and initial vigorous seedlings growth of Albizia saman in the nursery.
