A study was conducted to study the morphology of the forest cloves groups based on their sizes of their leaves, flowers, fruits and seeds, and to determine their potential yield and optimize their production system. The research was conducted for six months from January until June 2018 in Ambon, Maluku Province, Indonesia. The research used a random sampling technique to > 15-year-old trees in productive clove forest maintained by the local farmer in Ambon. The observation and recording was conducted at several stages of clover growth, namely bud sprouting, flower bud, blooming, perianths and anthers senescence, unripe green and ripe fruits. Different size groups of forest cloves have significant differences in the duration of flower and fruit formation. Forest cloves with large leaves, flowers, fruits and seeds had quicker ripening process than the othersize groups, but their fruits were longer to ripen. Flower from the medium size group had the shortest duration to develop its flower and form its fruit, whereas the smallest type took the longest time in fruit formation process but the duration of fruit ripening was similar to those from large morphology. Among the three different sizes of forest cloves in Maluku, the trees with large leaves, flowers, fruits and seeds group are the best to be commercially developed due to its earliest time to harvest and large flower sizes. Forest cloves are best harvested when the flowers are fully matured, indicated by one or two flower buds from one inflorescence have bloomed.
Abstract. Mahulette AS, Alfian A, Kilkoda KA, Lawalata IJ, Marasabessy DA, Tanasale VL, Makaruku MH. 2021. Isolation and identification of indigenous Arbuscular Mycorrhizal Fungi (AMF) of forest clove rhizosphere from Maluku, Indonesia. Biodiversitas 22: 3613-3619. Forest clove is classified as wild-type and endemic to the Maluku (Moluccas) Islands, Indonesia. The different condition of growing areas causes various types of Arbuscular Mycorrhizal Fungi (AMF) associated with forest clove. The study aimed to identify and obtain indigenous AMF inoculums from the forest clove rhizosphere from two distribution areas in Maluku. The results of AMF identification found two types of spores from the genus Glomus in the rhizosphere of forest cloves from Ambon Island with a spore density of 35/50 g of soil. In comparison, three spores were found in Seram Island, two from the genus Scutellospora and one from the Acaulospora. With an overall spore density of 5/50 g of soil. After culture trapping, there was a change in type and an increase in spore density in soil samples from the rhizosphere of the two forest clove distribution areas. Soil samples from Ambon after trapping culture obtained two new types of spores from the genus Acaulospora with a total spore number of 57/50 g soil while in soil samples from Seram found three new types of spores from the genus Glomus with a total spore count of 104/50 g of soil.
Abstract. Mahulette AS, Alfian A, Suyadi, Supriyanto, Situmorang J, Matatula AJ, Kilkoda AK, Nendissa JI, Wattimena AY. 2022. Type and morphological character of local clove (Syzygium aromaticum) from Maluku, Indonesia. Biodiversitas 23: 1301-1309. Maluku Islands are known as the origin for the distribution of cloves (Syzygium aromaticum L.) in the world, where the diversity of clove germplasm is high. So far, information on the diversity of local clove morphology in Maluku is still very limited. The study was aimed to characterize the morphological diversity of local clove accessions in Maluku. The study was conducted in three distribution areas in Maluku, namely Ambon Island, Seram Island, and Haruku Island. Characterization was carried out on 130 local clove accessions of Maluku based on 32 morphological characters. The exploration identified nine types of cloves, namely Tuni, Forest Clove, Raja, Boiselang, Zanzibar, Bogor, Jinten, Tae, Damar, and three variants of Forest Clove, two variants of Raja, and two variants Zanzibar. Forest cloves, Raja, Boiselang Jinten, Tae, Damar are classified as wild-type cloves, while Tuni, Zanzibar and Bogor cloves are classified as cultivated cloves. The Hierarchical Cluster Analysis (HCA) obtained 2 large groups of local cloves with 57% agro-morphological differences. The first group is Forest Clove and Boiselang, while the second group is other local clove accessions (Tuni, Jinten, Red Zanzibar, White Zanzibar, Bogor, Damar, Tae, and Raja). The Principle Component Analysis (PCA) shows a total diversity of 66.7% with 4 characters based on grouping. These cloves are also categorized into wild type, cultivated, aromatic, and non-aromatic types.
The objective of the study is to reach shorter seeds of forest cloves through the application of growth inhibitors, namely paclobutrazol. The study used a randomized block design (RBD) one factor with three replications. The experimental factor was 5 concentrations of paclobutrazol which were 0 ppm (control), 25 ppm, 50 ppm, 75 ppm, 100 ppm. The results revealed that the concentration of paclobutrazol 75-100 ppm produces shorter forest clove seedlings with higher leaf chlorophyll content.
