Abstract

Dioscorea tuber has many benefits, for example as food or as traditional medicine. The high carbohydrate and protein contents make this plant suitable as a food. However, the presence of crystal oxalate, that causes irritation is an disadvantage aspect on the development of this species. Both of wild and cultivated species will assure the gene flow which is important in efforts to improve the tuber quality should be examine further.  This research aimed to observe the biodiversity of Dioscorea in Bali and Lombok, to recognize the utilization and to reveal their nutrients (carbohydrate, protein and fat) and also the contents of calcium oxalate. The results showed that there are five Dioscorea spesies, namely  Dioscorea alata L. (ubi) (11 cultivars), Dioscorea esculenta (Lour.) Burkill (ubi aung), Dioscorea hispida Dennst. (gadung), Dioscorea bulbifera L. and Dioscorea pentaphylla L.   The highest carbohydrate content (87,42% ) is found in D. alata (ubi ungu cultivar) from Lombok,  while the highest protein content (5,05%.) is found in D. alata (ubi dadap cultivar) from Singaraja, Bali.  Furthermore, the highest percentage of fat content (0,85%) is found in D. bulbifera from Karangasem, Bali, whereas the high quantity of glaucomannan (44,52%.) id found in D. pentaphylla from Tabanan, Bali, while D. esculenta from Jembarana, Bali has the  highest calcium oxalate (0,57%), and D. alata (ubi injin cultivar) from Karangasem, Bali has the least calcium oxalate (0,18%).

Abstract

The Lesser Sunda Islands of Indonesia are composed of small islands scattered from Bali to Timor Island. We analyzed a molecular phylogeny of Adiantum collected from Lesser Sunda Islands to reveal its phylogenetic relationships. A total of 12 species of Adiantum from this region and seven species from Java Island were collected and used in this study. Two cpDNA regions (rbcL and trnL-F) were chosen as markers and phylogenetic analyses were conducted using Neighbour-Joining (NJ) and Maximum Parsimony (MP) methods. The tree topologies reconstructed by NJ and MP from specimens used in this study and other species downloaded from GenBank are congruent in which trees are divided into five major clades. Adiantum species of Lesser Sunda Islands are not monophyletic and comprises three clades, i. e. Clade I composed of A. hispidulum group, Clade III composed of A. peruvianum group and Clade IV or A. caudatum group, each together with extra-Lesser Sunda samples. No sample from Lesser Sunda Islands examined is located in Clade II (A. tenerum group) and V (A. capillus-veneris group).
