Abstract

ABSTRACTSpecies Identification of Scarlet gourd (Coccinia grandis (L.) Voigt) in Three Population inYogyakarta. Papasan is a dioecious plant belongs to the family Cucurbitaceae. This plant iscommonly used as vegetable, anti diabetic, anti bacterial, and anti diarrhea. In Daerah IstimewaYogyakarta, there were two varians of Papasan (Papasan I and II), found in three population(Ngebel, Berbah and Gajah Wong Riverbank). They differ in phenotype, especially in shapeand taste of fruit. Genotype observation using squash method on the root tips with modificationin the duration of maceration were used in this research indicated that cells devided of PapasanI at about 8-11.30 a.m, while Papasan II at about 08.30-09.30 a.m, 11 a.m-00.30 p.m and 2-2.30p.m. The chromosome number of both Papasan is 2n=24, contains of 22 autosomes and 2 sexchromosomes. The karyotype formulas of Papasan I and II were 2n=24=20m+2sm+XX(m).Based on the statistic test, significant difference on chromosomes character between PapasanI and II was only in short arm of autosome pair number 5. The difference R value betweenPapasan I and II was smaller than 0.25. It revealed that the both of Papasan is closely relatedand belongs to the same species of Coccinia grandis L. Character differences between bothof Papasan only revealed physiology adaptation.Keywords: Coccinia grandis L., Papasan, Chromosome, Karyotype.Kata kunci: Coccinia grandis L., Papasan., Cromosom, Kariotype.

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
