ORIGIN BONE AND SELAYAR DISTRICT, SULAWESI SELATAN Kurnia Makmur 1Fakultas Sains dan Teknologi, UIN Alauddin Makassar Jl. Sultan Alauddin No. 63 Samata-Gowa, Indonesia, *email: [email protected] ABSTRACT Selayar Islands Regency is one of the coconut (Cocos nucifera L.) producing centers in South Sulawesi. C. nucifera from this area is one type of coconut that fills the market spread across several areas in South Sulawesi. Coconut character as a determinant of consumer attractiveness. In addition, the character of a plant can be used as a step in conservation, cultivation, and germplasm efforts. One solution is to characterize the morphology of these plants. This study aims to analyze and determine the morphological characters of C. nucifera from Bone Selayar Islands district. This research was conducted in the mountainous area of Bone Regency and the coastal area of Selayar Islands Regency. The coconut plant samples observed were deep type coconut plants (C. nucifera L. var typical). Each area was observed as many as 10 accessions of C. nucifera which were randomly selected in the farmer's. The object of the analysis used a descriptive method based on the International Plant Genetic Resources Institute (IPGRI) coconut descriptor manual (International Plant Genetic Resources). The sampling technique was carried out by accidental sampling. Morphological characters C. nucifera observed were tree height, stem diameter, number of fruits, fruit size, and leaf color. The results showed that coconut plants from Bone and the Selayar Islands generally had almost the same morphological characters, the only difference being in the average number of fruits per tree, fruit size, trunk diameter and tree trunk height.

C. nucifera plant INTRODUCTION age is estimated to reach 80-90 years C. nucifera is a member of the Cocos (Tjitrosoepomo, 1989). This type of genus, Arecaceae family. Has a tree coconut takes many roles in people's lives. habitus, unbranched, rounded trunk, According to Kriswiyanti (2013) of the 11 midrib leaves; fruit, oblong; the color of the coconut cultivars used in religious fruit is green, bright orange, and yellow. ceremonies on the Bali Province is better This plant consists of two varieties, namely most of them are deep type coconuts (C. the deep coconut (C. nucifera L. var nucifera var. typical). typical) and the early coconut (C. nucifera Coconut (C. nucifera) is a strategic L. var Griff). (Chan & Elevitch, 2006). commodity that has social, cultural, and The inner type coconut (C. nucifera L. economic roles in the lives of Indonesian var typical) is generally cross pollinated, people. The benefits of coconut plants lie the tree height is about 15 - 35 m, the not only in the flesh of the fruit which can base of the tree has a bulb (the base of be processed into coconut milk, copra, and the stem looks like swelling), the length of coconut oil, but all parts of the coconut the leaves ranges from 5-7 meters, plant have great benefits.

This plant has high economic typical has never been done in South value (Leterulu et al., 2019). All parts of Sulawesi. This research is the first step to the coconut tree can be used for human find coconut plants that have superior benefit, so this tree is often called the tree characters. The effort taken is to of life. Roots, stems, leaves and fruit can characterize the morphology of several be used for daily human needs. According coconut plants that are popular in the local to research results (Diba et al., 2018) market. The diversity of morphological conducted with literature studies, characteristics of plants is an important interviews, surveys and observations thing to study. because it is a guide to get showed that there were 68 types of important characters that can be used for medicinal herbs used by the The Sultanate conservation, germplasm, and cultivation of Yogyakarta royal family made from purposes (Reed, 2008). There are several coconut. environmental factors that can affect morphological characters including This plant with a million benefits comes climate, temperature, soil type, soil from the coastal areas of tropical Asia and conditions, altitude, and humidity (Sitompul the Pacific. While the center of diversity is & Guritno, 1995). Based on this spread almost all over the world. In description, researchers are interested in general, this plant likes humid tropical identifying the character of coconuts that areas and grows well at an altitude of 100- grow in different areas. The purpose of the 500 m above sea level (Hartawan & study was to determine the morphological Sarjono, 2016). character of the deep coconut plant that Selayar Islands is one part of South grows in the Bone Regency and Selayar Sulawesi which is known as a center for Islands Regency. producing coconut (Cocos nucifera L.).
