The high valuable endemic commodities in Papua, Masoyi’s (Cryptocarya massoy) population facing great threat due to unsustainable harvest system. Generative propagation faces significant challenges due to seed characteristics and habitat conditions. Controlled conditions and the role of hormones have an important effect on generative growth. This study aimed to determine the influence of axenic culture with sterilization treatments Isothiazolone Biocide (IB) and 1-Naphtaleaneacetic Acid (NAA) in Murashige and Skoog (MS) medium on seed regeneration and to observe the development of seedlings at the acclimatization stage. The tissue culture method was used. The highest percentage of axenic cultures (57%) was obtained with 5% of BI. The germination rate of masoyi seeds was achieved by 100%. Furthermore, it showed varied responses depending upon concentrations of NAA, the addition of 1 ml l −1 NAA in MS medium is recommended. Acclimatization has been successfully carried out in the greenhouse (67% survival rate) and excellent seedlings growth at nursery (52.35 + 0.6 cm in height after one year transferred). The impact of the controlled conditions and the addition of NAA to axenic cultures in vitro increased the germination of masoyi seeds. Axenic culture and hormones were also important requirements for mass propagation of masoyi by tissue culture.
