Induksi Tunas Eksplan Biji Tembesu (Fagraea Fragrans Roxb.) Pada Media Wpm Dengan Penambahan Bap Secara In Vitro
One of the forest crop that has high prospect to be developed as quality for strong
wood is tembesu (Fagraea fragrans Roxb.). Its wood can be used for a heavy
construction and home construction. The seedlings produced from seeds of
tembesu in natural stands are rarely found seedling causing problems in
propagation. The aim of this research was to determine the effect of BAP and the
best concentration in inducing shoots from seed tembesu explants using in vitro
method. This research was conducted at the Laboratory of Integrated Biology
Department of Biology Faculty of Mathematics and Natural Sciences University
of Riau from December to April 2015. This research used a Completely
Randomized Design (CRD) with the concentration of BAP (0; 0,5; 1; 1,5; 2; 2,5;
3; 3,5; 4 mg/l) with 5 replications. Seeds the were planted in the media WPM for
120 days. The results of this research showed the highest percentage of shoots
formation is 100% contained in the control treatment. The highest number of
shoots produced in treatment of 1 mg/l BAP was 5,93 shoots with percentage of
shoots formation is 93,34%, average of shoot length 1,64 cm and the number of
leaves 3,00.
Keywords : BAP (Benzylaminopurine), in vitro, shoot induction, tembesu
(Fagraea fragrans Roxb.), WPM (Woody Plant Medium).
