Effect of Fungal Inoculation to Resin Content on Gaharu Plants (Gyrinops versteegii (Gilg.) Domke)

One of the commodities of non-timber forest products (NTFPs) is agarwood which has high economic value and as an export commodity. Agarwood is an aromatic substance in the form of lumps that are found between wood cells in various shapes and colors that are specific and have a resinous content. Resins are secondary metabolites that are produced by agarwood due to injury or infection by microbes. One of the microbes that infects aloes is a variety of fungi. This study aims to obtain effective technology in resin formation through a combination of fungal inoculation with strangulation in agarwood plants. This research is an experimental research with a factorial pattern of RCBD design. The first factor is strangulation namely: S0 (without strangulation) and S1 (with strangulation). The second factor is fungal inoculation, namely: J0 (without fungal inoculation), JF (Fusarium fungal inoculation), JR (Rhisopus fungal inoculation), JT (Trichoderma fungal inoculation). There are 8 treatment combinations, each combination treatment was repeated 4 times. Analysis of the resin by the extraction method using methanol as a solvent. Data were analyzed statistically with the variance test (ANOVA). If the treatment has a significant effect then it is continued with Duncans test at 5% level. The results showed that each treatment, namely strangulation and fungal inoculation, had significant effect until very real, while the combination treatment had no significant effect on agarwood resin content. The highest resin content was obtained in the combination of strangulation treatment with trichoderma fungi inoculation (S1JT) of 9.87%.
