Abstract

Masoyi (Cryptocarya massoy) is one of the high economic value, non wood forest products endemic to Papua. Development of masoyi plants currently are constrained by meeting the needs for quality seeds in a large quantity on time. Therefore, vegetative propagation become one of the solutions for this problem. The aim of this study was to get the best media, cutting materials, and doses of growth regulators for vegetative propagation of masoyi. Completely randomized factorial design was used. The first factor was the media of cuttings (soil+sand (2:1, v/v), coconut fiber+husk (2:1, v/v), and sand media). The second factor was cutting materials derived from 1 year old seedlings (the upper shoots and the down shoots). The third factor was the concentration of growth regulators (0; 500; and 1,000 ppm of NAA). The root percentage was influenced by media, the shoots, and growth regulator NAA. Root length was influenced by media as a single factor and the interaction between media and the shoots. The number of leaves was influenced by the media, while the number of roots was not influenced by each single factor and their interactions. Media was a critical factor for the success of masoyi cuttings. Thus, the combination of soil+sand (2:1, v/v) media with the upper shoots is a recommended treatment for masoyi shoot cuttings, where the combination is not influenced by the growth regulator NAA.
