Abstract

Studies of insectivorous plants diversity and photosynthesis rate of pitcher plants in Natuna Island was conducted on August 2011, Survey in eleven villages conducted to determine the species found in the visited sites, Bioscientific Portable LCI ADC Photosynthesis System used for measurement of pitcher plants photosynthesic rate, The results shows that there are three families of insectivorous plants founded in study sites, namely Nepenthaceae, Droseraceae and Lentibulariaceae, Six species of Nepenthaceae were found (four species and two natural hybrids) i,e; N. gracilis, N. ampullaria, N. rafflesiana, N. reinwardtiana, N. x hookeriana and N. x trichocarpa. While from family Droseraceae and Lentibulariaceae were found only one species respectively, which is Drosera burmanni and Utricularia bifida. Nepenthes reinwardtiana has the highest rate of photosynthesis namely 21,05 µmol/m /s, followed by N. gracilis (17,66 µmol/m /s), N. rafflesiana (16,6 µmol/m /s), N. x hookeriana (15,84 µmol/m /s) and N. ampullaria (9,96 µmol/m /s).

Abstract

Nepenthes spp. (pitcher plants) are carnivorous plants, because it can trapping and digesting insects and other small animals in their pitcher as their food. In 1996, there were 80 species noted in the world. Nowadays, the number has increased up to 139 species and 68 species(48.9%) of whom live and grow on various islands in Indonesia, such as Sumatra (34 species), Kalimantan (22 species), Java (3 species), Sulawesi (11 species), Maluku (3 species) and Papua (11 species). Herbarium Bogoriense-Research Center for Biology-The Indonesian Institute of Sciences (LIPI), as the central storage plant specimens in Indonesia, currently holds 2135 sheets of 72 species of Nepenthes are collected from various islands in Indonesia and from other countries. This paper will review the current number of Nepenthes and its distribution in various islands in Indonesia.
