Morpho-Agronomical Diversity of Forest Clove in Moluccas, Indonesia

Abstract

Forest clove (Zyzygium aromaticum) is a type of wild clove found in Moluccas. The increasing interest of farmers in cultivating this plant leads to complete their information of morpho-agronomical characteristics which could provide diversity reflecting morpho-agronomical their distribution areas. This study aimed to characterize the morpho-agronomical traits of Forest clove plants in Moluccas. By survey, Forest clove more than 15 year old tree totalling of 50 populations were observed their 54 morpho-agronomical characteristics in two areas (Ambon and Seram) from March to June 2018. Two aromatic cloves, namely Tuni and Zanzibar were used for comparative analysis. The results showed that Forest cloves had a similarity of 78% among the population and grouped into 3 groups with a morpho-agronomical variation of 22%. On the contrary, Forest cloves and comparators (Tuni and Zanzibar) had morpho-agronomical differences of 58%. Based on the main component analysis, there were 11 most influential characters of Forest cloves (leaf size index, leaf length, leaf width, leaf area, petiole length, flower length, diameter of flower tube, ripe flower weight, fruit length, fruit width, and fruit weight) which could be descriptors for this plant species.

Isolation and identification of indigenous Arbuscular Mycorrhizal Fungi (AMF) of forest clove rhizosphere from Maluku, Indonesia

“…Clove (Syzygium aromaticum L.) is one of the leading commodities in Maluku (Moluccas) (Alfian et al 2019;Mahulette et al 2019a;Hariyadi et al 2020). However, clove production is still around 40-60% of the potential production of plants (Mahulette et al 2019b).…”

“…Forest clove is an endemic plant from the Maluku Islands (Hariyadi et al 2019;Mahulette et al 2020aMahulette et al , 2019bMahulette et al , 2020bMahulette et al , 2019a. The fast growth and robust root system allow the association of this clove with AMF (Hariyadi et al 2019;Mahulette et al 2019bMahulette et al , 2020a.…”

“…AMF from the forest clove rhizosphere has the potential to be explored as a biological agent in supporting clove productivity. The distribution area of forest cloves in Maluku includes Ambon Island (Hitulama and Hitumesing villages) and Seram Island (Latu and Hualooi villages) (Mahulette et al 2019a(Mahulette et al , 2019b(Mahulette et al , 2020a. It is possible to find mycorrhizae with different types and densities in two different distribution areas.…”

Analisis Rantai Pasok Komoditas Cengkih Hutan di Maluku

“…Dengan demikian dapat meningkatkan kekayaan plasma nutfah cengkih Hutan di provinsi Maluku. Kata Kunci: Ambon, cengkih liar, plasma nutfah cengkih PENDAHULUAN Kepulauan Maluku merupakan "The center of origin" sebaran cengkih di dunia (Alfian et al 2019;Hariyadi et al 2020bHariyadi et al , 2020aMahulette et al 2019c;Milind and Deepa 2011). Sebagai daerah asli sebaran cengkih, Provinsi Maluku memiliki kekayaan plasma nutfah cengkih yang cukup tinggi.…”

“…Salah satu spesies cengkih tipe liar yang mulai banyak diminati oleh petani terutama di wilayah sebarannya di Maluku adalah cengkih Hutan. Cengkih Hutan sebarannya luas di beberapa lokasi tertentu di Pulau Ambon (Desa Hitulama, Hitumesing) dan di Pulau Seram (Desa Latu dan Hualoi) (Mahulette et al, 2019a(Mahulette et al, , 2019c (Hariyadi et al 2020a(Hariyadi et al , 2019Mahulette et al 2019cMahulette et al , 2019bMahulette et al , 2020aMahulette et al , 2020bMahulette et al , 2019a.…”
