Abstract

Fitmawati. 2006. Taxonomic Status of Mangifera laurina and its Related Species. Floribunda 3(2): 29-37.-This study is aimed to investigate the taxonomic status of species related to M. laurina, to find out whether they represent a natural species or should be placed in several different species. The result showed that morphological phylogenetic analysis supported the idea for separating three monophyletic species (M. laurina, M. aplanata, M. lalijiwa), considering that M. rubropetala and M. indica are synonym, and defining two independent lineages of sister group (i.e. the clade of M. lalijiwa and the clade consist of M. indica, M. laurina, M. aplanata  and M. rubropetala). Morphologically, M. lalijiwa is characterized by having glomerulate and glabrous inflorescence and tips of petal ridge free of the surface. In contrast, the other species usually posseses non-glomerulate and puberulous inflorescence and base or a half of base of petal ridge at free of the surface. Phylogenetic analysis of E-RAPD was incongruent with that of morphological analysis. However, the molecular phylogeny support whether that M. aplanata is separated from other species and that cultivars of M. lalijiwa are a monophyletic group.

Abstract

Fitmawati & Alex Hartana. 2010. Using RAPD and Enhanced-RAPD Markers to Distinguish Between Mangifera aplanata Kosterm. and Its Related Species. Floribunda 4(1): 1–4.— RAPD and E-RAPD analysis of M. aplanata were observed in reactions with 27 primers. Four out of these 27 primers produced 10 specific bands patterns. The result can distinguish M. aplanata from its closely related species. Fourtysix polymorphic fragments were amplified, which represents 89.1 percent of the total band number. The length of these fragment ranged from about 200 to 1500 bp.

Abstract

Ten distinct species of Mangifera were determined in central of Sumatera. This study aimed to characterize and to determine species of Mangifera based on the morphological character. The study had been conducted from December 2012 to March 2013 on 4 study sites in Riau Province by using a survey method and a direct observation. Fifty morphological characters were scored and analyzed using PAUP 4.0. The cladogram formed two main clades, clade I only consisted of M. kemanga and clade II consisted of M. foetida, M. odorata, M. indica, M. laurina, M. sumatrana, M. zeylenica, M. quadrifida, M. torquendra and Mangifera sp. The clustering results in two cladograms were mainly based on the the similarity of morphological characters dan based on the line of evolution.

Abstract

Indra Rijaya & Fitmawati. 2019. Jenis-jenis Bambu (Bambusoideae) di Pulau Bengkalis, Provinsi Riau, Indonesia. Floribunda 6(2): 41–52. —  Pulau Bengkalis merupakan salah satu pulau di sisi timur Sumatra yang didominasi lahan gambut dengan tumbuhan bambu yang dipercaya memiliki peran ekologis, hidrologis dan ekonomis. Informasi mengenai jenis-jenis bambu yang ada di Pulau Bengkalis sangatlah sedikit. Tujuan penelitian ini adalah untuk melakukan inventarisasi dan identifikasi jenis-jenis bambu berdasarkan karakter morfologi. Metode penelitian yang digunakan adalah metode survey eksploratif. Berdasarkan penelitian ini diperoleh empat marga asli bambu yakni Bambusa, Dendrocalamus, Gigantochloa, Schizostacyum dan satu marga introduksi (Thyrsostachys) Sembilan jenis yaitu (B. glaucophylla, B. heterostachya, B. multiplex, B. vulgaris, D. asper, G. hasskarliana, S. brachycladum, S. latifolium dan T. siamensis, dan satu varietas yaitu B. vulgaris var. striata dikemukakan.
