Abstract

The seed germination of pre-sowing treatments of Aquilaria agallocha and Shorea robusta seeds was conducted in the nursery of Bangladesh Agricultural University. The seeds were collected from 18 to 26 years old matured and healthy trees from various locations in Bangladesh and subjected to different pre-sowing treatments, i.e. control, soaking in normal and hot water (for different times), immersion in 80 % concentrated H₂SO₄ (for 20 minutes) and so on. Seed germination was carried out in poly-bags with a mixture of topsoil and cow dung in the ratio of 3:1. The result of analysis of variance (ANOVA) showedno significant differences between seed sources but the germination percentage among the treatment of the selected species was strongly significant with each another.
