Abstract

Hubungan kekerabatan (filogenetik) Litsea dan marga-marga yang berdekatan (Actinodaphne, Lindera and Neolitsea) dari suku Lauraceae telah diamati dengan menggunakan data molekular. Analisis dilakukan pada sekuens nukleotida dari gen-gen kloroplas matK dan ndhF. Walaupun gen-gen ini dikenal sebagai untaian pengkode yang berevolusi dengan cepat, tetapi untuk taksa tumbuhan yang diamati pada penelitian ini menunjukkan variasi yang rendah. Pohon-pohon filogenetik hasil analisis gabungan dari sekuens nukleotida matK dan ndhF menunjukkan bahwa marga Litsea tidak monofiletik. Di antara empat seksi dari marga Litsea (seksi Tomingodaphne, seksi Litsea, seksi Conodaphne dan seksi Cylicodaphne), hanya seksi Litsea yang monofiletik.

Abstract

Fenologi adalah telaah penampakan periodisitas pada tumbuhan dalam hubungannya dengan iklim, seperti waktu pembungaan dan flushing. Flushing yaitu pertumbuhan tunas/flush secara serempak. Tujuan penelitian ini adalah mengamati pertumbuhan tunas daun dalam merespon intensitas cahaya dengan posisi tumbuh berbeda dan faktor lingkungan yang mempengaruhinya. Metode yang digunakan adalah deskriptif dengan pengambilan purposive sampling, flush dibedakan posisi tumbuhnya yaitu terminal dan aksilar dalam kondisi terpapar dan ternaungi. Laju tumbuh Amherstia nobilis Wall. dan Brownea capitella Jacq. di daerah terpapar cahaya lebih cepat dibandingkan daerah ternaungi. Laju pertumbuhan diiringi dengan perubahan warna. Perubahan warna pada daun  A. nobilis berlangsung selama dua bulan lebih cepat dari B. capitella. Intensitas cahaya dan posisi tumbuh (terminal dan aksilar) berpengaruh pada pertumbuhan kedua spesies.

Abstract

Climate change, including warming and drying, is currently the biggest challenge for plant regeneration. We conducted two experiments on how temperature affected the germination of Pittosporum pullifolium and P. spicessens, both endemic to Central Papua highlands. P. pullifolium habitat temperature at night could reach 8°C whereas P. spicessens habitat temperature ranged from 19°C early in the morning up to 26°C at midday. The first experiment was to understand the effect of chilling on P. pullifolium germination initiation. Our study showed that P. pullifolium was dependent on cold stratification for its germination. Without cold stratification the germination was absent even though the temperature range of sowing environment is at ca. 13–26°C (Cibodas Botanic Gardens). With a cold stratification at 6–8°C (constant) for more than a month, germination of P. pullifolium occurred, with better germination rate under a light. Subsequently we carried out extended cold stratification for a month and interestingly, the germination still occurred but now it is better under dark condition. For P. spicessens, the germination at its habitat temperature range (Wamena) and in the warmer environment (Bogor Botanic Gardens), both occurred at more than two weeks after sowing.

Abstract

Gunung Halimun National Park (GHNP) is one of the remaining tropical forest in Java, still has high interaction with people who live in the surrounding areas.Eventhough there were some studies on ecology and ethnobotany in this area,it is still lacking of information on these subjects.This paper presented the results of ethno-ecology studies at several areas in GHNP such as East Halimun sector (around Gn.kendeng) and South Halimun sector (around Pangguyangan). The studies were carried out through vegetation analysis with Random Quadrats method and Participation method with interview technique.By these methods data were collected for the Important Value Index (IVI) and the Use Value Index (UVI) of species.These values showed that rasamala (Altingia excelsa), for tree stage, has the highest IVI and UVI but for the sapling stage the IVI is low. Kianak (Castanopsis acuminatissima) for tree and sapling stages the IVI is high but the UVI is low, while for maja (Magnolia macklottii), the UVI is high but the IVI is low for both tree and sapling stages. Based on these data, analyzed was done regarding the presence and the prospect of these species, in the context of the lifestyle of the villagers.
