Kultur in Vitro Biji Duku

. This experiment was conducted at the tissue culture laboratory of Indonesian Fruits Research Institute at Solok, from July to December 1999. The objective of this experiment was to find out suitable medium for growing langzone explants. The results indicated that a suitable media for growth of seed explant on the initiation stage was WPM + 0.5 ppm BAP without NAA during one week and subculture medium for multiplication stage was WPM + 1 ppm BAP without NAA. Highest number of adventitious shoot and shoot length were 6.67 and 5.4 + 0.2449 cm, respectively. The use of 0.5 ppm of BAP associated with 0.1 ppm of NAA was essential for obtaining the vigor plantlets. Maximum root number, 20,33 were obtained on media WPM + 2 ppm BAP + 0.2 ppm NAA
