REKAYASA PEMBENTUKAN GAHARU PADA POHON KARAS (AquUaria malaccencis, Lamrk) DENGAN MEDIA BIAKANISOLAT JAMUR YANG BERBEDA

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.
