Morphophysiological Analysis of Gmelina Arborea Roxb in Community Forest in Botolempangan Village, Sinjai Barat

Abstract

Abstract Gmelina arborea Roxb is a valuable plant that has great potential in various applications, including the timber industry. This study aims to analyze the morphophysiological aspects of gmelina, but knowledge about the morphophysiological characteristics of this plant is still limited. The data collection method involves direct measurements in the field and the use of special measuring equipment to obtain accurate data. The collected data was analyzed statistically using the appropriate method. This study was conducted by collecting 75 samples of gmelina leaves in the community forest in Botolomenpangan Sinjai Barat Village. Morphological parameters include color, namely, green, light green and spotted green. The shape of the leaves is shaped like a heart (cordate). The shape of the leaf tip is tapered while the shape of the base of the leaf is flat like a straight line (Truncate). The shape of the gmelina leaf edges is jagged and flat. The shape of the gmelina leaf bones is pinnate and the texture of the leaves is smooth and shiny. Physiological parameters starting from the largest chlorophyll content are at the location of taking 2 meters from the soil surface which is equal to 0.03610. The water content in gmelina leaves has the same high value starting from the location of taking the base, middle, and ends which is 9.9774, while the highest leaf area is in gmelina leaves which is 37.21 with the location of taking the base. The results of this study are expected to provide a better understanding of the morphophysiological characteristics of gmelina. This information can be used in a variety of applications, such as plant breeding and increasing wood production.
