Taxonomic Affinity of Poaceae Family Based on Morphological Characters

This study aims to analyze the relationship among species in Poaceae family based on their similarities morphological characteristics. The method used was a taximetry describing taxonomic affinity characteristics of plants, including leaves, stems, roots, flowers, and fruit. Morphological character data compiled Ms Excel, representing each organ scoring data. Furthermore, results were analyzed with NTSys-PC version 2.02i program, final presented as dendrogram. research show five members family, Zea mays, Oryza sativa, Saccharum officinarum, Pennisetum purpureum Cymbopogon citratus, showed that mays citratus had closest coefficient 0.47. In contrast, most distant purpureum, 0.25.ABSTRAK: Tujuan dari penelitian ini untuk menganalisis kekerabatan antar spesies dalam satu famili berdasarkan persamaan sifat dan ciri morfologinya. Metode yang digunakan adalah metode taksimetri menjelaskan kekebrabatan fenetik karakter morfologi tumbuhan meliputi daun, batang, akar, bunga, buah. Data disusun pada Matriks Ms. Excel mewakili masing-masing organ, skoring morfologis. Selanjutnya hasil dianalisis dengan program versi akhir disajikan bentuk dendogram. Berdasarkan lima anggota Poaceae, antara lain menunjukkan bahwa hubungan memiliki paling dekat koefisien 0.47 sedangkan jauh 0.25.
