A macro-somatic propagation study was conducted to assess the effects of rooting hormone and the level of concentration to the rooting performance of Bahai (Ormosia calavensis Azaola ex Blanco) and Bakan (Litsea philippinensis Merr.). The study was carried out in the clonal nursery of Central Mindanao University, Msuan, Bukidnon, Philippines. The experimental design used was the 2 x 4 factorial experiment arranged in Complete Randomized Design (CRD) replicated five times.  The two tree species served as Factor A: Bahai and Bakan; while levels of Indole-3-Butyric Acid (IBA) served as Factor B: control – no auxin , 100 ppm, 300 ppm, and 500 ppm. Findings show that Bahai cuttings exhibited statistically higher rooting performance compared to Bakan in terms of root length and number of roots treated with 300 ppm of IBA. Data show that Bahai had an average root length of 2.042 cm compared to Bakan with only 1.355 cm. For the number of roots, Bahai had an average of 1.855 compared to Bakan with 1.376. Between the two species used, Bahai showed higher survival rate of 84.42% compared to 57.63% for Bakan. Findings suggest that both species can be treated with 300 ppm of IBA to enhance higher rooting percentage where it produces greater number and longer length of roots. It is recommended that Bahai and Bakan tree species can be potential species for propagation using macro-somatic technologies.
