Abstract

Salamah A, Oktarina R, Ambarwati EA, Putri DF, Dwiranti A, Andayani N. 2018. Chromosome numbers of some Asteraceae species from Universitas Indonesia Campus, Depok, Indonesia. Biodiversitas 19: 2079-2087.  Asteraceae is the largest plant family, comprising of more than 1,600 genera and 23,000 species with a worldwide distribution. Many species of Asteraceae are found to be very significantly abundant in a range of habitats and are used as sources of medicines, food, forage, and other useful products. Many cytological studies have been carried out on Asteraceae. However, information about the chromosome numbers of Asteraceae in Indonesia is still very limited. In this study, the chromosome numbers of 15 species of Asteraceae found around the Universitas Indonesia campus were counted. For chromosomal preparations, the root/shoot tips were pretreated with 2 mM 8-hydroxyquinoline, stained with aceto-orcein, prepared using the squash method, and then observed with a microscope. Of the 15 species, 12 showed variation in chromosome numbers: Cosmos caudatus, Elephantopus scaber, Tridax procumbens, Mikania micrantha, Sphagneticola trilobata, Ageratum conyzoides, Cyanthillium cinereum, Chromolaena odorata, Synedrella nodiflora, Youngia japonica, Eclipta prostrata, and Porophyllum ruderale. The other three species showed no variation in chromosome number: Emilia sonchifolia (2n=10), Sonchus arvensis (2n=18), and Cosmos sulphureus (2n=24). We also found new variations in chromosome numbers that have not yet been listed in the Index to Plant Chromosome Numbers (IPCN).

Abstract

Salamah A, Luthfikasari R, Dwiranti A. 2019. Pollen morphology of eight tribes of Asteraceae from Universitas Indonesia Campus, Depok, Indonesia. Biodiversitas 20: 152-159. Asteraceae is one of the largest flowering plant families in the world consisting of a high diversity of species that possess many macro-morphological characters. Ecological pressures have resulted in this highly varied morphology. Our research aims to describe the pollen morphology of the Asteraceae for species occurring in Depok Campus of Universitas Indonesia. Pollens of 14 species from eight tribes were extracted using acetolysis method and observed under a light microscope. The result showed that pollen unity, shape and pollen surface appeared to be differentiating characters of the Asteraceae from other families, while polarity and symmetry characters can be distinguishing characters at higher levels of the family such as subdivisions. Aperture characters were useful to differentiate between tribes. The shape of pores and size of pollen were not useful in differentiating between tribes, but may differentiate between lower taxa. The results of this study could be used as supporting data for regrouping taxa within the Asteraceae using morphological features.
