Abstract

Porophaloenopsis laycockii is an epiphytic orchid, endemic to Borneo. The orchid is not widely known since this orchid is rare and the trade of this species is restricted by the law. An observation was made to provide information on plant morphology and leaf anatomy of the species. Among various characters recorded, it was noted that the pencil-or-rat-tail-like leaf is about 5.66 mm in diameter and up to 1 m in length. It has relatively large stomata measuring 66.8 x 57.3 pm with low stomata density of 16.3 stomata per mm° of leaf surface area. These characters may influence its water management so that the plant should be grown and maintained in shade for better establishment.

Abstract

Coelogyne merupakan anggrek asli Indonesia yang mempunyai ukuran bunga relatif besar dan warna menarik. Penyimpanan biji Coelogyne perlu dilakukan untuk menjaga keragaman spesies tersebut. Percobaan penyimpanan biji pada tujuh spesies anggrek Coelogyne pada suhu -20oC telah dilakukan selama empat tahun di PKT KR–LIPI. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap, dengan faktor media yang diperlakukan pada masing-masing spesies Coelogyne. Empat macam media kultur yang digunakan untuk menguji perkecambahan biji adalah KCA (Knudson C), KC (modifikasi Knudson C), VW (modifikasi Vacin and Went), dan HS (modifikasi Hyponex).  Uji viabilitas biji diamati setelah biji disimpan selama 0, 1, 2, 3, 6, 9, 12, 18, 24, 36, 48 bulan. Hasil penelitian menunjukkan bahwa biji Coelogyne spp. mampu berkecambah di  empat media percobaan. Viabilitas  biji Coelogyne spp. menurun dalam waktu tiga bulan, enam bulan, sembilan bulan, dan seterusnya tergantung pada spesies Coelogyne tersebut.  Biji Coelogyne yang dapat disimpan selama 1–2 tahun adalah C. pandurata, C. asperata dan C. rumphii, sedangkan biji yang dapat disimpan selama tiga tahun adalah biji C. foerstermannii dan C. pulverula.  Biji C.rochussenii dan C. celebensis dengan masa hidup yang singkat harus ditanam segera setelah panen, dan selanjutnya disimpan dalam bentuk kultur bibit in vitro atau biji sintetis melalui enkapsulasi protocorm.

Abstract

Averrhoa dolichocarpa is a wild starfruit from Papua and Averrhoa leucopetala is a wild starfruit from Gorontalo. Both starfruits have unique characters of the leaves, inflorescence, flowers, and fruits. The study was conducted from February 2012 to May 2012 by observing the wild starfruits collections of Bogor Botanical Garden. Innitiation of Averrhoa dolichocarpa inflorescence takes 8-14 days, the small bud growing in 11-15 days, after one day the large bud will open and the anthesis last after 3 days. The fruit will develop and mature after 40-45 days. The flower and fruit drop rate is quite high, mostly caused by strong wind. The chlorophyll content of the leaves are very dynamic and influence by the environment and the wide of the canopy. Whereas initiation of Averrhoa leucopetala inflorescence needs 30-34 days, the small bud growing in 12-15 days, the large flower bud will open after 1 day, anthesis last after 5 days, and the fruit development needs 40-42 days to mature. Anthesis of the flowers occurred at 4:00 to 6:00 a.m. The flower and fruit drop rate is also quite high. The chlorophyll content is more static and tends to increase when the fruit developed.

Abstract

A research was conducted to study the effect of fruit maturity on seed germination capacity of four Pyracantha species, i.e. P. koidzumi, P. angustifolia, P. crenato-serrato and P. fortunea. The fruits were collected from Cibodas Botanic Garden in two different states of fruit maturity, namely physiological maturity and harvest maturity. In general, seeds of Pyracantha spp. were starting to germinate epigeally in 5 — 14 days after sowing and the states of fruit maturity influenced seed germination capacities. In P. angustifolia and P. crenato-serrato, seed germination capacities were better if the seeds were extracted from brightly colored mature fruit (physiological maturity). Meanwhile, in P. fortune and P. koidzumi, better germination capacities were obtained in seeds extracted from dark collored drying mature fruit (harvest maturity).

Abstract

Rafflesia spp. (Rafflesiaceae) have a strategic value from both scientific and conservation viewpoints. To date only very few attempts have succeeded in growing the species ex situ and the main protection measures have been by in situ conservation. More detailed studies are required to understand the relationships between Rafflesia spp. and their host plants in order to improve their management and conservation. Studies on the anatomy, in vitro culture and seed germination in connection with conservation have been conducted in the Bogor Botanic Gardens. Effort to transfer Rafflesia patma to an ex situ conservation area has produced some flowers. However, we encountered a bigger challenge to maintain the long term presence of R. patma in ex situ conservation, since a high number of individuals is required to make the viable population.

Abstract

Hoya spp. (Apocynaceae: Asclepiadoideae) has differences in leaf type, there are succulent and non succulent leaf types.  Anatomical structure of Hoya spp. leaf has not been widely studied, especially for the non succulent type. The aims of this research were to explore the diversity and relationship of non succulent Hoya, based on leaf anatomical characters represented by eight species i.e. H. bandaensis, H. campanulata, H. chlorantha, H. cilliata, H. coriacea, H. coronaria, H. densifolia and H. multiflora. Hoya leaf anatomical characters were observed on the paradermal and transversal section and analyzed by using IBM SPSS version 19 sotfware for cluster analysis. According to the paradermal observation, stomata were present at lower surface (hypostomatic) for all species, and amphistomatic (both surface) for H. densifolia.  The type of stomata is cyclocytic for all species. Clustered stomata were found in H. coriacea.  Observation on transversal section showed that all of species has the normal structure i.e cuticula, upper and lower epidermis, palisade parenchyma and spongy parenchyma with the variation in the layer thickness.  The cluster analysis resulted four groups at distance scale 19. Each group has specific characters. The first group has trichomes on both sides of the leaf surface. The second group has amphistomatic stomatal. The third group has thin leaves. The fourth group has the widest stomata.

Abstract

Morfologi kotiledon dari sebelas jenis tumbuhan suku Bignoniaceae diamati sebagai upaya untuk identifikasi lapangan. Kotiledon pada suku Bignoniaceae memiliki karakter unik dan jarang ditemukan pada suku tumbuhan lain. Ujungnya berbelah dua dan berbentuk hati. Karakter unik ini dapat digunakan untuk identifikasi tumbuhan di lapangan, terutama pada fase semai. Sudut kedua parakotiledon, sudut belahan pada ujung para-kotiledon, dan panjang parakotiledon dapat digunakan untuk membedakan tribus dalam suku Bignoniaceae. Namun demikian, penelitian lanjutan yang menggunakan lebih banyak jenis diperlukan untuk menguatkan hasil awal ini.

Abstract

Penurunan peranan suatu spesies dalam budaya masyarakat dapat menyebabkan kelangkaan bahkan kepunahan spesies tersebut. Seiring dengan program pemerintah untuk melakukan diversifikasi pangan, tanaman minor yang potensial sebagai sumber karbohidrat dapat dipopulerkan kembali dengan tujuan sebagai upaya konservasi tanaman tersebut. Terkait hal tersebut, kentang hitam (Plectranthus rotundifolius) dapat menjadi sumber pangan alternatif bagi masyarakat yang menempati daerah kering. Kentang hitam tidak hanya berperan sebagai sumber karbohidrat dengan indeks glikemik rendah, tetapi juga kaya vitamin dan sejumlah mineral penting. Informasi mengenai teknik budidaya menjadi hal penting yang perlu dipersiapkan dalam rangka pengembangannya. Penelitian ini dilakukan untuk menjawab pertanyaan mengenai teknik budidaya yang perlu dilakukan untuk meningkatkan kualitas hasil panen kentang hitam di pasaran. Penelitian dirancang berdasarkan Rancangan Acak Kelompok (RAK) dua faktor, yaitu aksesi dan teknik budidaya. Empat aksesi kentang hitam yang digunakan: Nganjuk, Sangian, klon 6G dan O3; dan empat jenis teknik budidaya: bumbun, pangkas, jerami, and pengangkatan tajuk) Setiap perlakuan terdiri dari empat ulangan, dengan tiga tanaman/ulangan. Pengamatan dilakukan pada parameter pertumbuhan dan hasil. Hasil penelitian  menunjukkan aksesi kentang hitam yang berbeda memerlukan teknik budidaya berbeda untuk meningkatkan hasil dan ukuran umbi. Penggunaan mulsa jerami padi pada budidaya kentang hitam dapat meningkatkan ukuran umbi kentang hitam di musim hujan.

Abstract

Plant communities have been attracting many scientists due to their complexity and unclear underlying mechanisms that support it. How large numbers of competing plant species manage to coexist, for instance, is one of the major unresolved questions in plant community ecology. Ecological niche concept is a classical theory which tries to address this question. The development of this concept will be presented in this paper. Recent studies, although few in number and incomplete in many ways, do suggest that plants segregate along various environmental niche axes. Although it is unlikely that niche separation along environmental axes is the only mechanism of coexistence in any large community, the evidence now suggests that ecological niche concept plays a more significant role than has been previously appreciated.

Abstract

Lasianthus, a member of the family Rubiaceae has potential for medicinal plants. The aims of the research were to find out the potential antibacterial activity of Lasianthus leaf extract and to investigate the effectiveness of plant propagation by stems cutting. The species tested were Lasianthus laevigatus Blume, L furcatus (Miq.) Bremek and L. cf. obscurus Blume. The extracted leaves in n-hexana, ethyl acetate and methanol were tested in vitro against Staphylococcus aureus and Escherichia coil activities that grown on medium of Mueller-Hinton agar. The methanol extracts of each plant material showed significant antibacterial activities on S. aureus and E. coll. Antibacterial activity increased with increasing concentration of the extracts. Plant propagation by stems cutting were done as a first step of conservation effort for respective species. Stems cutting of L. laevigatus, L. purpureus, L. furcatus, L. acuminatus, L rhinocerotis. and L. cf. obscurus with length of 10 cm were applied with Rotoon F to stimulate root growth. The result of plant propagation research showed that only the stems cutting of L. cf. obscurus grew well although roots did not grow until 4 months.
