Pengaruh Stressing Terhadap Percepatan Pembentukan Gubal Gaharu Pada Tanaman Gaharu (Aquilaria malaccencis, Lamk)
Abstract: Agarwood is an
aromatic substance formed as brown clumps, blackish brown in the lining of
agarwood, divided into 3 classses; agar, kemedangan, ash. Aqualaria malaccencis
has been known as an agar producing tree. Naturally, the forming of agar needs
teens years. Several method has been known formed agar through wounded to
Aquilaria malaccencis, Lamk. The reseach aimed was to test stressing at
Aquilaria malaccencis. Lamk in forming agarwood. This research was conducted at
Plot Forest Research Institute of Technology Fibers Forest at Ujungbatu, Rokan
Hulu, Riau for about 5 months, started from June to October 2011. Aquilaria
malaccencis, Lamk, was wound by given fisics stressing consist of without
stressing (P0), cordage with 1 ring (P1), cordage with 2 rings (P2), prunning
2/3 part crown (P3), and prunning 1/2
part crown (P4) then combined with biological stressing by inoculation of
Fusarium sp. The stressing was designed by randomized block design Duncan’s
Multiple Range Test at significant level of 5% was applied to compared physics
to agarwood producing. The changed of color and fragrance were analyzed by
Non-Parametric Test. Kruskal Wallis at significant level of 5% was applied to
evaluate significant treatments. Correlations Test was done between treatment
at significant level of 1%. The result showed that Aquilaria malaccencis, Lamk,
with fisics tressing (P1, P2, P3, dan P4) showed wood colour changed after 1
month inoculation of Fusarium sp. Stressing cordage with 2 rings (P2) which
followed by inoculation of Fusarium sp at Aquilaria malaccencis, Lamk, resulted
26,76 g dryweight of brown agar with
best fragrance at level 2 after 5 months stressing. Based on statistical
analysis, there were significant between stressing and agar formed. The best
stressing at Aquilaria malaccencis, Lamk, was cordage with 2 rings. The result
of correlations test showed strong to very strong of infection area, color
changing, fragrans and dryweight of agarwood
