Observation of morphological and physiological characteristics on Abangares Mahogany (Swietenia macrophylla King.) In South Sulawesi

Abstract

The one of identification system using morphophysiological analyses for breeding program Mahogany is needed. Mahogany (Swietenia macrophylla) is a tree species which is easy to cultivate as it is able to thrive in a great variety of habitats and soil types. Here, we present a study on the relationship between morphological and physiological parameters on S. macrophylla. The study was carried out in a seed orchard of Mahogany in genetic resource area of 2nd Forest Seed/Seedling Office, Gowa district, South Sulawesi, Indonesia, in October 2017 up to March 2018. Morphological and physiological analyses were performed on 31 S. macrophylla leaf samples. The morphological parameters consisted of leaf color, leaf shape, leaf tip, leaf base, leaf margin, upper leaf surface texture, leaf venation, and tree diameter. Meanwhile, the physiological ones were chlorophyll content, leaf area, and water content. Leaf samples were divided into three colors, two leaf shapes, and three leaf base shapes. They also had tapered leaf tip, pinnate venation, and glabrous leaf surface. The chlorophyll content and leaf area had a very low coefficient correlation, whereas leaf area and water content showed very high coefficient correlation. The relation between morphology and physiology could be determined by the correspondence between chlorophyll content and leaf color. The higher chlorophyll content, the greener the observed leaf.

Sustaining angiosperms’ diversity of Bood Promontory and Eco-Park, Butuan City, Philippines: Step towards a community based-protection management program

“…As presented in Table 1, the Large-leaf Mahogany (S. macrophylla, King) has the highest counts, and only 1 shrub species is present, the Makahiya (Mimosa pudica, L.) that grows abundantly in tropical places (Ahmad et al 2012;Larekeng 2019). There were 4 tree species, and 1 herb species which are still unnamed.…”

Morphological Characterization of Purple Yam (Dioscorea alata) in Purwodadi Botanic Garden

“…Some of the leaves that appeared were not counted in this study because they were too small and young (just developing). Although the internodes have been formed, the leaves have not fully developed yet, and the characters are difficult to observe [14]. Therefore, immature leaves do not need to be counted when characterizing the morphology of a plant.…”

“…Fig. 3a shows two leaf color variations in the six observed accessions of D. alata which are pale green (30%) and dark green (40%), while three accessions (30%) could not be identified because the leaf size was too small due to new development and the morphology is not clear yet [14]. The results showed that the color of the leaf margins was identified as two groups of variations which are green (60%) and purple (10%) (Fig.…”

Aktivitas Antibakteri Secara In Vitro Ekstrak Metanol Biji Mahoni terhadap Escherichia Coli

“…Budidaya dilakukan dengan iklim kering dan diperlukan sistem pengairan yang baik. Studi melaporkan tanaman dari spesies yang sama tumbuh di lingkungan yang berbeda dapat menghasilkan konsentrasi yang berbeda dari senyawa metabolit sekunder (17). Peneliti tidak turut terlibat langsung dalam budidaya tanaman mahoni, sehingga kondisi lingkungan dan iklim tempat tumbuh mahoni yang digunakan tidak diketahui secara jelas.…”
