Vetiver oil is one of Indonesia's potential export commodities, but the quality of vetiver oil <br /> <br /> <br /> from Indonesian producers tends to be low. Glomus aggregatum is arbuscular mycorrhizal <br /> <br /> <br /> symbiotic with vetiver plant and function can increase the absorption of soil nutrients, so it <br /> <br /> <br /> can help increase the growth and quality of metabolite in vetiver oil. Secondary metabolites <br /> <br /> <br /> produced by vetiver can also vary in their components at different ages, so research is <br /> <br /> <br /> needed on secondary metabolites produced at any age difference in vetiver roots, either <br /> <br /> <br /> symbiosis or not, in order to know the right time to harvest secondary metabolites that <br /> <br /> <br /> desired. In this study was evaluated the effect of vetiver interaction with Glomus <br /> <br /> <br /> aggregatum on the growth of vetiver and quality also quantity of vetiver oil with different <br /> <br /> <br /> age variation. Vetiver aged 6 months, 9 months and 12 months were acclimatized, then <br /> <br /> <br /> inoculated with Glomus aggregatum for 4 weeks and observed growth, mycorrhizal <br /> <br /> <br /> infection test, tissue phosphorus (root and leaf) test, soil phosphorus test, terpenoid test, <br /> <br /> <br /> total oil and GC-MS test to determine the diversity of compound components in the oil. <br /> <br /> <br /> The results of some of these tests showed that plants with the highest wet weight (10.95 <br /> <br /> <br /> grams), highest root dry weight (0.82 grams), and highest leaf dry weight (1.15 grams) <br /> <br /> <br /> were at 12-month-old fragrant roots symbiotic with mycorrhiza, the highest test of infection <br /> <br /> <br /> is at the vine root age of 12 months (88%), highest root P levels at 9-month-old vine root <br /> <br /> <br /> symbiotic with mycorrhizal, P content of highest leaves at 12 months of symbiotic root <br /> <br /> <br /> with mycorrhiza, and terpenoids are found in the fragrant roots aged 6, 9 and 12 months. <br /> <br /> <br /> The results of this study indicate that root vetiver plants can grow optimally when <br /> <br /> <br /> innoculated with Glomus aggregatum. Acquisition of the largest volatile oil of vetiver was <br /> <br /> <br /> found in the 12-month-old vetiver plants symbiotic with mycorrhiza ie 3.43%. The result of <br /> <br /> <br /> GC-MS analysis showed that exudate released by vetiver plant was thought to be phenol <br /> <br /> <br /> compound (Phenol, 2- methoxy-4- (1-propenyl). Compound of metabolite of vetiver oil that <br /> <br /> <br /> symbiotic with mycorrhiza is more diverse and vetiver plants age 9 and 12 months have <br /> <br /> <br /> more distinctive compound of vetiver compared with root plants of 6 months old.
