Abstract

ABSTRACTStudy on foliar anatomic structure of tropical plants are useful to study various aspects of plant life related to photosynthetic, productivity, carbon sequestration, adaptation to environmental stresses as the results of global climate change, etc. This study was conducted to investigate foliar anatomic structure of ten tropical woody plant species including Barringtonia asiatica, Dracontomelon dao, Heritiera littoralis, Diospyros discolor, Calophyllum inophyllum, Antidesma bunius, Schleichera oleosa, Syzygium cumini, Madhuca longifolia dan Adenanthera pavonina; also to discuss its implication to ecophysiological adaptation to tropical dry climate. The results showed that ten woody plant species studied had variation of adaptation pattern to dry tropical climate, exposure to high light intensity or open shade and photosynthesis activity. Plant species in Group II (Antidesma bunius, Madhuca longifolia and Adenanthera pavonina) has relatively higher adaptation compared to Group I (Diospyros discolor, Calophylum inophyllum, Dracontomelon dao, Schleichera oleosa, Heritiera littoralis, Baringtonia asiatica and Syzygium cumini). Some foliar anatomic structures including palisade shape and size, stomatal index, stomatal density, spongy mesophyll thickness, the ratio of P/T and P/S are important characters that can be used as indicator of changes in environmental factors; particularly the density of stomata as indicators of climate change in dry tropic area.Keywords: adaptation, dry climate, eco-physiology, foliar anatomy, woody plant

Abstract

Percentage changes of litter nutrient due to decomposition process of four deciduous plant species in Purwodadi Botanic Garden. The nutrient release pattern of plant litter is different among species. Decomposition and nutrition release of organic material was observed in four species Swietenia macrophylla, Lagerstroemia speciosa, Ficus benjamina and Kigelia Africana in Purwodadi Botanic Garden. Litter mass was measured and chemical compositionwas analized including poliphenol, celulose, lignin, carbon (C), Nitrogen (N), C/N ratio, phospor (P), and Kalium (K) during 3 months. Litterbag method was applied in this research. Freshlitters were brought into bag and placed in the forest floor. Litterbag and litter chemical monitoring was established once a week. The research result showed that C ratio of four species in early phase increase then decrease in late phase of incubation and significantlydifferent from initial phase except in F. benjamina. N ratio decreased in first month and increases until late phase of incubation. C/N ratio increase in early phase then significantly decreasesuntil 3 months incubation. P ratio tends to decrease in first and third month. Ratio of polyphenol and Lignin decreases, however celluloses increase. The litter of four species has low chemical quality, respectively have low C/N ratio (< 25 %), lignin < 15 %, poliphenol < 3 % and (L+Pp)/ N > 8 %. Consequently, the litter tends to immobilize than mineralize. It effected to high ratio ofN such in L. speciosa. Decreasing and releasing of N in K. Africana showed that its nutrient transfer is better than in other species. P ratio quickly decreases in first 4 weeks of decomposition, it showed that P is not a limiting factors in species decomposition, relatively.Keywords : Litter, decomposition, percentage changes, nutrient

Abstract

As indicator for environmental disturbances, the understory is an important structural and functional component of forests ecosystems. Hence, this study was conducted to investigate the diversity and composition of understory plants in the lowland forests adjacent to the trekking paths along Semut Bay (dock entrance) to Segara Anakan Lagoon and some coastal areas in Sempu Island, and to detemine their association with the underlying environmental factors as disturbance indicators by the presence of understory invasive alien species (IAS). Sixty six plots of 2 x 2 m2 were established to analyze the understory vegetation, the site profiles and the environmental variables. A total of 135 understory plant species belonging to 108 genera and 60 families were recorded within the 66 plots of the study areas. Poaceae was the dominant family, followed by Compositae, Phyllanthaceae, Sterculiaceae, Rubiaceae, Putranjivaceae and Cyperaceae. The understory communities in the lowland forest adjacent to Semut Path were dominated by tree seedlings and had a relatively fewer composition of shrubs. Coastal areas, which have more open canopies, were dominated by grasses and shrubs. Some dominant native understory species include Ckistanthus ohlongifolius, Pterocymbium javanicum, lschaemum muticum, Guettarda spedosa, etc. Indicating disturbance, 12 understory IAS were found in the study areas. Four of these are among the world’s worst invaders (Chromolaena odorata, Imperata tylindrica, Lantana camara and Spathodea campanulata), and three are noxious weeds (Cyperus rotundus, Eleusine indica and Imperata cylindricd). The light intensity and air temperature were strongly positively associated with disturbed sites, while relative humidty, soil pH, and elevation were associated with less disturbed sites. These study results provide the scientific basis for management and recommendations on the current diversity status of the understory plant species at Sempu Island, hoping that these would justify further conservation of indigenous species and their protection from these disturbances.

Abstract

Chromium (Cr) is commonly found in water containing waste of batik industry. Several aquatic plants that usually become weeds, such as Sagittaria lancifolia and Pistia stratiotes, can be utilized in the remediation of heavy metal contamination in aquatic environment. The objective of this study was to elucidatethe potential of aquatic plants of Sagittaria lancifolia and Pistia stratiotes in the phytoremediation of chromium contaminated water and its effect of growth of water spinach (Ipomea reptans). The results of showed that Sagittaria lancifolia and Pistia stratiotes were potential to be used as phytomediators and they were able to reduce Cr levels in contaminated water in treatments of PSM1 (Pistia stratiotes + 2 ppm Cr) by 1,757 ppm or 87,85%, PSM2 (Pistia stratiotes + 5 ppm Cr) by 4,379 ppm or 87,59%; SLM1 (Sagittaria lancifolia + 2 ppm Cr) by 1,785 ppm or 89,23%; SLM2 (Sagittaria lancifolia + 5 ppm Cr) by 4,032 ppm or 80,64%. The concentration of Cr on the water after phytoremediation had a significant impact on the Cr levels contained in water spinach. The treatment of SLM1 (Sagittaria lancifolia + 2 ppm Cr) had the highest Cr absorption score in water spinach at 0,184 ppm, while the treatment of TTM1 (control + 2 ppm Cr) had the lowest Cr absorption score at 0,098 ppm. The results of this study also indicated that water spinach was not safe for consumption as the Cr level in the plant was greater than the threshold limit of Cr level in food of 0,05-0,2 ppm.

Abstract

The existence of industries can cause severe environmental pollution. The impact of environmental pollution can be reduced by phytoremediation by using aquatic plants such as Echinodorus radicans and Pistia stratiotes. This study was aimed to determine the potential of aquatic plants Echinodorus radicans and Pistia stratiotes as lead (Pb) remediators. This study used a completely randomized design with six treatments, i.e. T0F1 (without plant/control 2 ppm), T0F2 (without plant/control 4 ppm), T1F1 (Echinodorus radicans 2 ppm), T1F2 (Echinodorus radicans 4 ppm), T2F1 (Pistia stratiotes 2 ppm), and T2F2 (Pistia stratiotes 4 ppm). The result of this research indicated that T2F2 (Pistia stratiotes 4 ppm) treatment reduced Pb by 92,53% which was higher than T1F2 (Echinodorus radicans 4 ppm) treatment of 89,59%. Pistia stratiotes more effectively reduced Pb content than Echinodorus radicans. Pb contaminated water that was previously used for growing Echinodorus radicans and Pistia stratiotes could be safely used for watering spinach plant (Amaranthus tricolor) to improve its growth

Abstract

Mango is a tropical fruit plant. Distribution center of mango species in Indonesia are in Sumatra and Borneo. Among the species, Mangifera indica L. has more varieties than most other species. Eight varieties of M. indica L. which are Blenyik Bulat, Wader, Bapang, Gondo Lumut, Madu, Endog, Gandik Luyung and Krasak Candi has been studied to recognize the phenotypic character of superior germplasm of mango varieties. Qualitative and quantitative characters of varieties have been measured. Varieties of Madu, Endog and Krasak Candi has a sweet fruit flavor and relatively non-fibrous with the highest scoring value 14 and 12. Quantitatively, it is known that the size of mango varieties under study pertained small, range from 0.12 to 0.3 kg. However, Blenyik Bulat variety with very small fruit has a very attractive appearance, yellow when it is ripe with a uniform color. Based on the ratio between the weight of fruit peel and seeds, it is known that the varieties have thick flesh, heavy pieces of meat more than 60%, variety Blenyik Bulat 80%, Wader 67%, Madu 73%, Bapang 96%, Gondo Lumut 96%, 94% Endog, Gandik Luyung 93%, 89% Krasak Candi. From phenotypic characters of mango variety, we can conclude that the variety of Madu, Endog, and Krasak Candi are quite excellent and their fruit can be developed for domestic consumption, as they have sweet taste. While for other varieties such as Blenyik Bulat, Gondo Lumut, and Bapang, can be developed for processing fruit as juice or dessert even can be developed for export consumption for example to Europe and Australia, as they have sour taste.     Keyword: Manggo, Character, Phenotypic.

Abstract

Bioinformatics are a reliable method to trace biological information in the molecular level including the analysis of molecular phylogeny relationship of species. This paper discuss about the phylogeny relationship of eleven species of Phalaenopsis (Orchidaceae) based on internal transcribed spacer (ITS1 and ITS2) gene, 5.8 ribosomal DNA by bioinformatics applications. The method of this study is a database search in Gene Bank through the NCBI website (http://www.ncbi.nlm.nih.gov) to search nucleotide data and DDBJ (http//www.ddbj.nig.ac. jp) for the use of software BLAST and the EBI (http://www.ebi.ac.uk) for nucleotide alignment of similarity search. Cladogram shows that P. javanica and P. patherina have a very close relationship. Both species are also still closely related to P. cornu-cervii. Species P. modesta, P. tetraspis and P. lueddemannian are separated each other that can be revealed to have distant phylogenetic relationship than other species in the genus. Species P. amboinensis form a cluster with the species P. floresensis and P. mannii. However, P. sumatrana was closely related to P. corningiana. The cladogram showed that formation among Phalaenopsis species was not apparently grouping. Moreover, there is a large group consisting of P. amboinensis, P. Sumatrana, P. cornu-cervi, P. pantherina, P. floresensis, P. mannii and P. corningiana, while P. modesta, P. tetraspis and P. lueddemanniana were not clustered into the group.Keywords: Bioinformatics, phylogenetic relationship, Phalaenopsis, databases, internal transcribed spacer (ITS) gene.
