Summary : A greenhouse nursery experiment was conducted at the Tarlac College of Agriculture in Camiling, Tarlac to determine the best location of cuttings in the ortet and the appropriate level of concentration of indole-3-butyric acid for the micropropagation of mamalis under low-cost, non-mist propagator.The stem cuttings treated with 4000 ppm and 5000 ppm IBA consistently registered the best performance in terms of root production, shoot development. They also recorded tha highest percentage of survival per cutting and the least was 0 ppm (control), Most of the cuttings rooted after three months. Generally, there is a great potential of using low-cost, non-mist propagators using juvenile plant material and appropriate level of concentration of IBA in the mass production of quality planting stock of mamalis.
