Abstract

The impact of altering IBA concentration, cutting location, and the effect of treatment interaction on the survival, initiation, and development of Katmon of (Dillenia philippinensis) cuttings was explored using an experimental design. Katmon cuttings were used to test the treatment^s effectiveness in terms of percent survival, percent rooting, percent callusing, percent shooting, and length of adventitious root. In addition, the study intended to identify the optimal cutting location and IBA concentration for Katmon survival and rooting. In CRD, a 3 x 5 factorial experiment was performed. The Katmon stem cuttings were stored in a non-moistened chamber until the data collection was complete. The interaction between cutting location and IBA concentration had negligible effects on survival rate, number of adventitious roots, number of shoots, number of calluses, root length, and shoot length. In terms of location and concentration, the study^s results revealed statistically significant variations in percent survival, percent rooting, average number of roots, number of callus, and average number of callus. Variations in survival, adventitious root, root length, and the number of calluses are inconsequential in terms of interaction and IBA concentration.
