ANATOMI HELAIAN DAUN MURRAYA SPP. (RUTACEAE) DI JAWA [The Anatomical of Murraya spp. (Rutaceae) Leaflet in Java] Tihurua, Eka Fatmawati; Astuti, Inggit Puji; Rugayah, Rugayah

Leaf anatomy of four species of Murraya (Rutaceae) have been examined. Murraya spp. leaf has dorsiventral type. Anticlinal epidermis cell wall present with straight-undulate and square-irregular shaped. Anomocytic stomata distribute only in the lower surface and simple trichome spread in both leaf surfaces except M. crenulata (Turz.) Oliv. which has trichome only in the lower surface. Mesophyll consist of 2 or more layers of palisade tissues in the leaf upper part and sponge below, but M. exotica L. has palisade tissue in both leaf side. Oil gland distribute in the mesophyll. Crystal present as prismatic (cuboid) and drusse type.

KOMPOSISI JENIS DAN POTENSI ANCAMAN TUMBUHAN ASING INVASIF DI TAMAN NASIONAL GUNUNG HALIMUN-SALAK, JAWA BARAT [Species Composition and Threat Potential of Invasive Plants Species in Gunung Halimun-Salak National Park, West Java] Sunaryo, Sunaryo; Uji, Tahan; Tihurua, Eka Fatmawati

A study on species composition and threat potential of invasive plant species was conducted in the Gunung Halimun-Salak National Park,Cidahu Resort, West Java. We developed two plots of different altitudes. The result showed that there were four invasive alien species possessing potential threat to the ecosystem and native species in the National Park, i.e. Piper aduncum (Piperaceae, with an Important Value of 20,70); Calliandra calothyrsus (Mimosaceae, IV = 9,11), Austroeupatorium inulaefolium (Asteraceae, IV = 18,77), and Clidemia hirta (Melastomataceae) as shrub. The threats of invasive plants happen in open forest area and could occur from the residential or public places.

PENELITIAN NYALI DI TAMAN NASIONAL GUNUNG GEDE PANGRANGO DAN TAMAN NASIONAL GUNUNG HALIMUN SALAK, JAWA BARAT, INDONESIA [Research on gall in Mount Gede Pangrango and Mount Halimun Salak National Parks, West Java, Indonesia] Rachman, Erlin; Tihurua, Eka Fatmawati; Sunaryo, Sunaryo

Research on gall (including field and laboratory observations and field collecting) have been conducted in the Mounts Gede Pangrano (MGPNP) and Halimun Salak National Parks (MHSNP). This research focused on gall shapes, host plant species, and parts of the host plants infected by galls. The result showed that there were 169 gall numbers in MGNP and 127 numbers in MHSNP have been collected. Distribution of plant species infected by the galls were rather same in the both conservation areas. In MHSNP seven families mostly infected by galls: Araceae, 4 species of 5 gall numbers collection in the family (=4/5), Elaeocarpaceae (5/5), Euphorbiaceae (7/9), Lauraceae (8/11), Moraceae (6/7), Melastomataceae (4/4) and Rubiaceae (9/12). In MGPNP the composition is only fairly different: Araliaceae (4/6),Euphorbiaceae (8/13), Lauraceae (9/12), Melastomataceae (5/6), Moraceae (13/22), Myrtaceae (9/11) and Rubiaceae (6/13). At least 23 gall shapes were found in both locations. The most common shape of galls found in MGNP was irregular, while in MHSNP was globular.Galls were mostly (90%) collected from leaf including peduncles and leaf venations. The other parts included twigs, branches, stems, flowers,and fruits. The most common insect found investing galls (i.e. insect gallers) was the midges (54.4%) followed by mites (18.5%), psyllids (11.1%), thrips (6.3%), coccids (1.9%), and aleurodes (1.9%).

STUDI ANATOMI DAUN JENIS-JENIS AVERRHOA DI INDONESIA UNTUK MEMPERTEGAS STATUS TAKSONOMINYA Sunarti, Siti; Rugayah, Rugayah; Tihurua, Eka Fatmawati

Leaves anatomy of Averrhoa spp. in Indonesia have been studied for supporting morphological character which used to recognize four species: A. carambola, A. bilimbi, A. leucopetala and A. dolichocarpa. The letter two species have leave crowded terminally or near the top of stem similar to those leave of A. bilimbi, whereas the fruit shape similar to A. carambola.The result of this study indicated that, these four species showed differently in their thickness of lamina and epidermis cell as well.

Wood density is the functional character which has important role in the function of ecosystem. Stem and branch wood density have different trait and effect on its ecosystem processes. The objectives of this research are to know the diversity of stem and branch wood density and to analyze whether branch wood density could be used to estimate stem wood density in the Mount Papandayan. Six plots of 0.1 ha at different sites (three plots each in interior and edge forest) were established. Branches were collected from trees with diameter at breast height larger than 10 cm, while stem wood density data were obtained from some wood density sources. Research results showed that stem wood density ranges were 0.35?0.82 g/cm3, while branch wood density ranges were 0.33?0.61 g/cm3. Average of branch wood density was lower (0.48 ± 0.09 g/cm3) than stem wood density (0.61 ± 0.1 g/cm3). Linear regression analysis indicated that branch wood density could be used to estimate stem wood density of trees in Mount Papandayan which is showed by R2 value and correlation coefficient of 0.28 and 0.55 (p value < 0.001) respectively.
