Abstract: This study is to investigate the in vitro propagation and ex vitro root formation of Gnetum gnemon var. griffithii Markgr (G. gnemon), one of the nutrient-rich forest vegetables. The results showed that MS medium supplemented with 1.5 mg l-1 BAP was the most suitable combination for shoot formation after 90 days of culture. The combination between 1 mg l-1 BAP and 0.5 mg l-1 NAA gave the best in vitro rooting rate (40%) after 60 days culture. After 60 days tranfered to the greenhouse, plantlets which planted on the substrate of coconut fiber powder had a better growth (plant height of 6.14 cm, root length of 6.90 cm) than those on a combination substrate of coconut fiber powder and sand (1:1). In additional, plantlets treated with 3.0 mg l-1 IBA for 1 minute had the highest root formation rate (80%), the greatest root number per plantlet (2.80 roots), and the longest root (1.76 cm) when compared with those in different of treatment.
