The objectives of the research are:
a. To compile a database of clove varieties, distribution, and ecology in Maluku
b. To obtain data on the morphological and agronomic character of local clove in Maluku
c. To analyze the genetic diversity of cloves in Maluku, followed by SSR marker.
d. To find potential use of local clove in Maluku through analyzing of essential oils component
After the research finished, the output and outcomes we expect are:
a. At least two articles submitted to a scientific journal (Biotropia)
b. Research report
c. Clove database on website
d. New information on variety and essential oils of clove
e. The future outputs: Book (Clove of Maluku)
1. Local cloves in Maluku were identified in 2 groups with an agro-morphological difference of 57%, namely the Forest clove accession group (group I, II, III) and Boiselang as the first group and other local clove groups as the second group (Tuni, Jinan, Zanzibar Red, White Zanzibar, Bogor, Damar, Tae, Raja group I, and Raja group II).
2. The Principle Component Analysis (PCA) results of 32 agro-morphological characters in 130 local clove accessions of Maluku obtained a total diversity of 66.7% with four groups of characters based on grouping.
3. The Raja group I clove cultivation system had the highest average biomass content, while the highest percentage of land cover in the study was found in the Damar clove cultivation system.
4. The accession of wild-type cloves to the non-aromatic group represented by forest cloves group III has a close genetic distance to cloves cultivated from the red Zanzibar aromatic group, while cultivated cloves from the aromatic Tuni group have a genetic distance closer to wild-type cloves. type) non-aromatic Raja group.
5. The Physico-chemical properties of non-aromatic wild-type clove oil represented by three accession groups of forest cloves in Maluku did not meet the oil Physico-chemical standards. In contrast, the cultivated type cloves of the Tuni and Zanzibar aromatic groups as a whole met all Physico-chemical standards for clove oil.
6. Non-aromatic wild type cloves represented by three accession groups of forest cloves in Maluku have major components, namely germacrene-D, -cubebene, eugenol, - cadinene, -copaene, methyleugenol, while cloves cultivated from the aromatic groups of Tuni and Zanzibar red in the form of eugenol, caryophyllene, eugenyl acetate, and - humulene.
