HUBUNGAN KEKERABATAN FAMILI ASTERACEAE BERDASARKAN CIRI MORFOLOGI MENGGUNAKAN METODE TAKSIMETRI SEBAGAI SUMBER BELAJAR BIOLOGI

Asteraceae is a tribe of flowering plants that has the second most numerous types after the Orchidaceae tribe. The taximetry method is to determine plant relationships quantitatively. The aim of this research is to determine the relationship between plants belonging to the Asteraceae family in terms of their morphological characteristics using the taximetry method. The research results obtained 15 different species from the Asteraceae family in the cities of Malang and Batu. The species that are most closely related are species E (Cosmos bipinnatus Cav.) and G (Taagetes patula L.) with a euclidean value of 1,477. The most specific characteristic of the morphology of the Asteraceae family lies in the shape of the flowers, but other morphological characteristics such as the shape and surface of the stem and the edges and surface of the leaves are also relatively the same. The phenetic relationship of 15 species of Asteraceae members forms 2 large groups that have the closest relationship, namely group 1 consisting of Helianthus anuus L., Zinnia elegans Jacq. Dahlia pinnata Cav., Dahlia coccinea, Garbera jamesonii, Gazania linearis, Chrysanthemum morifolium, Chrysanthemum indicum, Melampodium divaricatum Rich., and Tanacetum parthenium, group 2 consists of Cosmos bipinnatus Cav., Tagetes erecta L., Tagetes patula L., Argyranthemum fructescens L., and Callisthepus chinensi.
