Abstract

Leaf NPK fertilizer experiments on pitcher plant (Nepenthes neglecta and ventrata) conducted in May 2008 to March 2009 in a greenhouse, Botany Division, Research Center for Biology-LIPI, Cibinong Science Center, Cibinong. The objective is to study the effect of leaves NPK fertilizer on the growth of the two Nepenthes species tested. Experiments using Random Complete Factorial Design with two factors, namely the two Nepenthes species and threedoses of fertilizer each treatment repeated six times. Growth parameters measured include; long shoot leaves, plant height, number of leaves, number of mature pitchers and growth pitchers. Results showed that the dose of NPK fertilizer provided (2 and 4 ml / lt) have no effect on plant height and number of leaves, but little effect on the number of mature pitchers thanthe control plants. The statistical tests also showed no interaction between the two Nepenthes species with a given dose of fertilizer on the growth of plants. Minimum-maximum temperature recorded in the greenhouse during the experiment was 22.20C and 38.50C. Meanwhile, air humidity between 43,6-64,7%.Key words: Leaf NPK fertilizer, plant growth, pitcher plant

Abstract

Population analysis of Nepenthes spp in peat swamp forest was conducted atKalampangan, Central Kalimantan on November-December 2007. This place include to part of one million hectare area of peat land project in 1996 which are planed to convert agricultural land. Peat swamp forest is one of commonly Nepenthes habitat at Kalampangan. One plot (50 x 100 m) was establihed for population analysis study. We found 230 individu from three species, that is; Nepenthes ampullaria, N. rafflesiana and N. gracilis. In study site, N. ampullaria is dominant species with Important Value (IV) is 120,43% and then followed by N. gracilis (IV= 97,30%) and N. rafflesiana (IV= 82,27%).Key Words : Population analysis, Nepenthes, peat swamp forest, Kalampangan,

Abstract

Research the structure and composition of vegetation, biomass estimation, carbon content and the rate of photosynthesis was conducted in Citalahab Central Village,Gunung Halimun-Salak National Park, West Java, on August 2010. The purpose of research to determine the components and characteristics of each tree species at the study sites associated with biomass, the rate of CO2 assimilation and transpiration. Results showed that, the form of classified forest area of primary forest with a little disturbed. There were recorded 337 individual trees (stem diameter > 10 cm) per hectare from 71 species, 50 genera and 32 families. Lauraceae, Fagaceae, Myrtaceae, Rubiaceae and Meliaceae are the 5 most common families found in the plot area, thatis dominated by Altingia excelsa, Blumeodendron elateriospermum, Ardisia zollingeri, Gordonia excelsa, Tricalysia singularis, Castanopsis acuminatissima, Knema cinerea, Laportea stimulant, Vernonia arborea and Dysoxylum excelsum. Estimated biomass recorded of 304.5 tons dry weight / ha with a carbon content of 152.3 tons / ha of basal area of 28.89 m2/ha. Quercus oidocarpa, Litsea noronhae, Saurauia nudiflora, Castanopsis argentea and Altingia excelsa has recorded the highest photosyntheticrates compared with other species. While the highest transpiration rate is owned by the Macaranga triloba, Sandoricum koetjape, Prunus arborea, Urophyllum corymbosum and Altingia excelsa.
