abstract
Agarwood (Aquilaria agallocha) is a highly prized tropical tree valued for its aromatic resin, widely used in perfumery, traditional medicine, and cultural practices. However, its natural regeneration is constrained by factors such as low seed viability, excessive harvesting and vulnerability to fungal infections. Agarwood seeds exhibit recalcitrant characteristics, losing viability rapidly upon desiccation, which limits their storage potential. Sustainable cultivation of agarwood is hampered by a limited understanding of its seed biology, including germination behaviour and physical traits. This study aimed to evaluate the effects of various pre-sowing treatments on seed germination, as well as to analyse the physical traits of agarwood seeds. Various pre-sowing treatments have been investigated to enhance agarwood seed germination rates. Germination trials were conducted under controlled conditions with seven pre-sowing treatments at ICAR Research Complex for NEH region, Manipur Centre. Results obtained showed that 24 hour soaking in water at room temperature yielded the highest percentage of germination at 63.33%. The longer soaking time significantly reduced germination and treated seeds with concn. H₂SO₄ had extreme damage on the seed upon germination. Physical analysis revealed that the seed of agarwood is small size and smooth coated. By employing improved germination techniques and sustainable propagation strategies, the conservation and commercial cultivation of agarwood can be significantly enhanced, ensuring its long-term economic and ecological viability.
