Abstract: Canarium strictum Roxb., belonging to the family Burseraceae of flowering plants, is a medicinally and economically important tree species. It is highly demanded for its aromatic resin which is being used locally or commercially. In India, the species is found in north eastern region, southern states, and the Andaman Islands. It is distributed in the tropical moist mixed deciduous forests up to an altitude of 1600 m. It has been observed that in the recent times, the natural population of the species is reduced drastically and the species has become rare and vulnerable in the country. For promoting commercial cultivation and management, a regeneration study was undertaken. The paper deals with the germination behavior of Canarium strictum where seed germination, seedling growth, and seedling survival of the species were investigated. Different pre-seed germination treatments were applied where seed germination was highly effective in the treatments T7: IBA 1000 ppm (48.61 ± 10.69%) followed by the treatment T5: mechanical scarification (46.53 ± 4.81%) and treatment T8 with IBA 2000 ppm (45.83 ± 3.21%) where late arrival of germination was recorded in T1 (control) with 25.93% of germination. Earliest commencement of germination was found in T8: IBA 2000 ppm followed by T3: GA 1000 ppm. In case of Mean Germination Time (MGT), it was lower for treatment T7: IBA 1000 ppm and highest for treatment T1 (control). In all treatments, seedling survival did not show significant difference
