Abstract

A non-mist propagation study was conducted to assess the rooting responses of mayapis [Shorea palosapis (Blanco) Merr.] and narig (Vatica mangachaoi (Blanco) juvenile cuttings to various concentrations of indole butyric acid (IBA), napthalene acetic acid (NAA), and Superthrive Vitamin Hormone (StVH). It aimed to develop rooting protocols for such species intended for mass propagation. Results indicated that among the plant growth regulators (PGRs) used, IBA induced the highest rooting percentage of mayapis and narig as compared with NAA and StVH. In Phase 1 of the study, 100 ppm IBA induced a high rooting percentage of mayapis at 82.29%. In Phase 2, increasing the concentration of IBA to 150 ppm slightly increased the rooting percentage to 87.45%. The difference, however, was not statistically significant. In terms of the number of roots developed, no significant differences were observed among varying IBA concentrations (50 ppm, 100 ppm, and 150 ppm). IBA treatment, however, was significantly different from the control and StVH. Root lengths did not significant differ among treatments.
