Abstract

The main purposes of this research were to investigate whether the two distinct types of the morphological characterof Ranunculus triplodontus were genetically controlled or environmental influence. In order to prove the above,electrophoretic examinations were carried out employing for four enzyme systems. The medium support of polyacrilamide was chosen. The samples were collected from seven populations around central plateau and the leaves were used as the isozyme data. The result indicated that variation occurred in certained populations. However, this isozyme data were not able to separate the two types of R. triplodontus into different species. Based on the cluster analysis showed that three groups of seven populations of R. triplodontus were appeared. This research confirms that morphologically distinct species was not supported by the isozyme data, thus the variation found in certain population was mainly influenced by the environmental conditions, and therefore could not be considered as taxonomically distinct.© 2001 Jurusan Biologi FMIPA UNS SurakartaKey words: Ranunculus triplodontus, isozyme.

Abstract

The research was to find out similarity among soybean (Glycine max [L.] Merr.) cultivars in Java based on site planting by morphological taxonomy evidences. Fresh samples of soybean were collected from 20 sites in Java and 20 samples were collected in every site. Soybean was observed at flowering and seed maturing time. The similarity wasdetermined by Euclidean distance and clustered by average linkage. The result showed that soybean from Bantul wassplit by another 19 cultivars. The remaining cultivars were split into two groups. The first, i.e.: Tangerang, Garut, Wonogiri, Klaten, and Sukoharjo, and the second, i.e. Tuban, Wonosari, Pasuruan, Pati, Karawang, Yogyakarta, Sumedang, Purwokerto, Wates, Bojonegoro, Lumajang, Ngawi, Sleman, and Sukabumi. They were split into several little groups. The cultivars between Tuban and Wonosari, Ngawi and Sleman, also Tangerang and Garut had closed relationships. Keywords: soybean, planting site, relationship.

Abstract

The objective of the study was to know the taxonomic structure of the genus of Zingiber based on cytological characters such as ratio of number, shape and size of chromosome. Zingiber specimens were mainly from Bogorbotanical garden. There were seven species studied, Z. amaricans Nor., Z. aromaticum Val., Z. cassumunar Roxb., Z.gramineum Bl., Z. officinale Roxb., Z. ottensii Val. and Z. zerumbet (L.) J.E. Smith. Z. officinale (local name: Jahe)consinsting of 4 varieties, big ginger (jahe gajah), red ginger (jahe merah), small ginger (jahe emprit) and blue-darkbrowny ginger (jahe wulung). Species identification was based on the literature such as of Backer and Bakhuizen van den Brink (1968), Holttum (1950), and Burkill (1935). Semi permanent squash method using acetoorcein dye was used to prepare the sample (Darnaedi, 1991; Okada, 1981; Robert and Short, 1979). The results of the study indicate that the number of chromosomes of all species studied were the same, 2n=32. The length size of the first chromosome pair was about 2μm. The shape of the chromosomes was mostly metacentric. Length and shape of each pair of chromosomes were hard to be determined accurately using this method, so that the chromosomal karyotype map unable to be constructed in this study. Giemsa C-banding method might be used to solve theproblems.© 2000 Jurusan Biologi FMIPA UNS Surakarta

Abstract

The objectives of the research were to know: (1) the diversity of epiphyte species at the stand of puspa trees (Schimawallichii (D.C.) Korth.) in Cemoro Sewu and Cemoro Kandang of mount Lawu, and (2) the distribution and cover abundance of the species based on its location from the land surface. The research objects were all species of epiphyte plants on the stand of puspa trees. The procedures of data collection were including species collection in the field, make up herbariums, observation of epiphyte vegetation using transect method and morphology observation in the laboratory. The results show that in the south slope of the mount Lawu were found 23 species of epiphyte consisting 4 species of lichenes, 2 species of Fungi, 3 species of Bryophyte, 10 species of Pterydophyte, 2 species of Orchidaceae and 2 species of liana. The species with the highest density was Bryophyte, and the highest diversity was Pterydophyte. The height of the trees affects the distribution, diversity and density of the epiphyte plants.© 2000 Jurusan Biologi FMIPA UNS Surakarta Key words: Schima wallichii (D.C.)

Abstract

Litterbag experiment was carried out to determine the effect of crop residue application to soil fauna community andmungbean growth. The experiment arranged in randomized complete design with triplicate. The four treatment application of crotalarian, rice straw and banana’s aerial stem residues as well as without residue application as control. Soil fauna community and mungbean growth measured at 8 weeks after mungbean sown. Soil fauna extracted by modified Barless-Tullgren extractor apparatus. Height and dry weight of mungbean measured as crop growth parameters. The results indicated that the soil fauna densities and diversities as well as the growth of mungbean tended to increase by the application of crop residues. The effect of the treatment decreasing in thefollowing order: banana’s aerial stem residue > crotalarian residue > rice straw > without residue application. Therewere high correlation between mungbean growth and soil fauna diversities.© 2001 Jurusan Biologi FMIPA UNS Surakarta Key words: crop residue, soil fauna, mungbean.

Abstract

Azolla was a special fern that their associations with Anabaena azollae able to fix free nitrogen from air, to produce protein. Although by the ages, biota diversity those habits on the roots of Azolla increased and effected to protein concentration. The research was to find out population dynamics of biota on the roots of Azolla microphylla Kaulfuss and the growth peak. This study used Completely Randomized Design with 10 kinds of biota, i.e. bacteria, Fungi, Actinomycetes, Protozoa, Alga, Crustacean, Rotifers, Coelenterate, Insect and Molluscs, and it was used 3 replications. Research was conducted within 4 weeks and the populations of biota were observed every week. Data were statistically analyzed using Analysis Variant and Duncan’s Multiple Range Test. The population dynamics ofbiota on the roots of Azolla microphylla Kaulfuss were influenced on its quantity and composition, and the growthpeak is done in 2nd week.© 2001 Jurusan Biologi FMIPA UNS SurakartaKey words: Azolla, population dynamics, biota.

Abstract

Indonesia is an archipelago of 17.508 islands with land width of 1.9 millions km2 and sea of 3.1 millions km2, having many types of habitat and become one of biodiversity center in the world. There are about 28.000 plants species, 350.000 animals species and about 10.000 microbes predicted lived endemically in Indonesia. The country that represents only 1.32% of the world having 10% of total flowering plants, 12% of mammals, 16% reptiles and amphibian, 17% birds, 25% fishes and 15% of insects in the world. Most of the biodiversity were not investigated and utilized yet. The direct use of the biodiversity is not any risk, and in addition, between government, society and industries sometime does not have the same view and attitude. Habitat destruction and over-exploitation have caused Indonesia having long list of endangered species including 126 birds, 63 mammals and 21 reptiles. The extinction of some species occurred just few years ago like trulek jawa (Vanellus macropterus), insectivore bird (Eutrichomyias rowleyi) in North Sulawesi, and tiger sub species (Panthera tigris) in Java and Bali. It seems that now is time for all Indonesians to introspect and look for the way that can be used for preserving biodiversity.© 2001 Jurusan Biologi FMIPA UNS SurakartaKeywords: biodiversity, Indonesia, endangered species
