Abstract

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

“Tuni” and “Afo” cloves are endemic clove varieties from the Maluku islands. Until now, there is still little information on morphological diversity in plant populations and information on the characteristics between the two varieties. The research aims to provide information on the morphological diversity and characteristics of “Tuni” and “Afo” cloves from the Maluku Islands. Morphological characterization of the “Tuni” variety of cloves was carried out at its distribution location on Ambon Island, Maluku Province. In contrast, “Afo” cloves were characterized at their distribution location on Ternate Island, North Maluku Province. The research was carried out in July 2023-May 2024. The used for morphological identification was the modified Tropical Fruit Descriptors. The characterized clove plants consisted of 30 “Tuni” clove plants and 30 “Afo” clove plants, so a total of 60 plants were characterized. The results of the Hierarchical Cluster Analysis (HCA) based on 54 morphological characters that were carried out showed two groups with a dissimilarity coefficient of 44%. The first group is a group of “Tuni” clove accessions, which are clustered with a similarity of 91%, and the second group is a group of “Afo” clove accessions, which are clustered with a similarity of 90%. The results of Principle Component Analysis (PCA) obtained a total diversity of 75.4%, where the specific characteristics of “Tuni” cloves obtained were stem bark color, crown shape, branching angle, leaf thickness, old leaf color, shoot color, leaf petiole tip color, flower stalk weight, flower length, flower tube diameter. The specific characteristics of “Afo” cloves obtained from PCA are plant height, stem circumference, North-South canopy width, East-West canopy width, leaf length, leaf texture, leaf spiciness, ripe picked flower color, picked ripe flower crown color, ripe fruit color, and color seed.

Abstract

Clove “Raja” is one of the local Maluku clove germplasm, which has characteristics similar to cultivated cloves and wild types. Until now, very limited information that are available on the morphological character of clove “Raja”. This study aims to provide basic information on the morphological diversity of “Raja”. The study was conducted at the location of the distribution of cloves “Raja” in Mamala village, Leihitu sub-district, Central Maluku district, Maluku province, in June-August 2022. The descriptors used referred to Tropical Fruit Descriptors, with some modifications. The clove “Raja” that were characterized belonged to the farmers and consisted of 30 accessions of cloves that were over twenty years old. The characterization variables included the characters of trees, stems, branches, leaves, flowers, fruits, and seeds. The results of Hierarchical Cluster Analysis (HCA) on 30 plant samples based on 54 morphological characters obtained two accession groups with a dissimilarity coefficient of 41%. The results of the Principle Component Analysis (PCA) got a total diversity of 70.5% where the first group consisted of accessions of cloves “Raja” group I having identifiable characters in the form of leaf area, leaf length, leaf width, and leaf tip shape; while the second group of clove accessions of “Raja” group I in the form of stem circumference, petiole length, flower length, fruit length, fruit width, and fruit weight. Characteristics of accession of “Raja” cloves group II had distinctive morphological traits in the form of crown shape, upper surface of leaves, lower surface of leaves, leaf thickness, leaf texture, old leaf color, shoot color, leaf tip color, leaf aroma, leaf spiciness, flower stalk length, and seed color.
