Abstract:
Aganvood is an aromatic substance in the form of lump brown, blackish
brown till that forms the lining of aloe wood. One of agarwood-producing trees
were trees Karas (Aquilaria malaccencis, Lamrk). But this time due to rampant
illegal voting that without coupled with the correct information about the
technical causes of the declining harvest and including plants that are protected.
The research aims to stimulate the formation of a compound of aloes and
get inoculant formulations that can induce rapid aloes compound. This research
was conducted at Arboretum Balai Penelitian Hutan Penghasil Serat - Kuok.
Research will be conducted for ± 6 months ie from July to December 2010.
The research method using a randomized block design with 5 treatments,
namely in the drill without a given isolate / control (PI), isolate the fungus
Fusarium sp. in solid medium with a dose of 2 g / hole (P2), isolates fungus
Fusarium sp. in solid medium with a dose of 4 g / hole (P3), isolates fungus
Fusarium sp. in liquid medium with a dose of 2 cc / hole (P4) and isolate the
fungus Fusarium sp. in liquid medium with a dose of 4 cc / hole (P5). Each
treatment consisted of 3 blocks. Obtained data were analyzed range, if a real
influence on the level 5%, then followed by DMRT test. The parameters measured
were: infection, changes in wood color, fragrance and yield levels.
After a month inoculated it changes color. Browning symptoms that form
on stems spread vertically follow the direction of stem vascular tissue. Brown
stem tissue surrounding the drill holes indicates there has been accumulation of
secondary metabolites in response to wounding or fungal infection Fusarium sp.
These changes are characteristic has been the formation of pig aloes.
The best dose is the use of liquid isolate as much as 4 cc per hole drill that
produces yield of 2.21% with a rate of less fragrant scent at the age of 5 months
after inoculation and brown. This shows the indication and the correlation
between media culture isolates against infection agarwood-producing trees.
