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