Respon Eksplan Biji Gaharu (Aquilaria malaccensis Lamk.) Terhadap Pemberian 2,4-D Secara In Vitro

Edit
ABSTRACT: Aquilaria malaccensis Lamk. is one of the tree forest that are continuosly exploited. Currently, the Indonesian  export  of  the  agarwood  was  decreasing  because  its  population  was  endangered  by  excessive logging. Agarwood propagation need technology for reproduction of agarwood multiplication. Research  was  undertaken  to  determine  effect  of  plant  growth  regulator  2,4-D  on  seed  explant  A. malaccensisi in vitro has been performed. This research had purpose to determine  response of seed explant  of  gaharu  by  giving  different  cosentration  2,4-D  and  to  measure  growth  and  developtment  result  of  seed explant of gaharu. This research used a complete Randomized Non Factorial Design with using MS as basic media  by  added  2  ppm  of  BAP.  The  treatment  consisted  of  2,4-D  2  ppm,  4  ppm,  6  ppm  and  8  ppm. Observation made explants fourty two days after planting. The parameter observed were the emergence of callus, callus color and  texture of the callus.  The result showed that callus was obtained as response of A. malaccensis seed explant with 2,4 D and BAP. The concentration 2,4-D 2 ppm showed the best result for the emergence of callus. Callus color is dominate by white and a bit yellow or scoring 4, and the callus texture is dominate by compact callus and compact with node.
