"ABSTRAKSikajau rimbo (Pterolobium densiflorum Prain) belongs to the Caesalpiniaceae family and was found growing at submontane zone at air Tarusan Nature Reserve, West Sumatera Province. It grows along river banks and hillslopes on rocky and sandy soils. It produces dense inflorescenes and winged pods with beautiful colour. Stem and leaf are thorny, which helps the plant to climb. Local people use the plant as a medicine for kidney-stone."

"Over one hundred species of Indonesia's native orchids had been propagated generatively at Bogor Botanic Garden during the last seven years. Germination of 100 species Vacin and Went and Hyponex media were varied in regard to their requiremnet. However, some orchids showed a tendency to germinate better in one of the medium. The result presented in this paper is designated as a guideline to put the priority setting of Indonesia's native orchid propagation program in Bogor Botanic Garden"

"ABSTRACTThe genus Amydrium belongs to the Araceae family, consists of five species that is A. hainanense H.Li, Y.Shiao & S.L. Tseng, A. sinense (Engl.) H.Li, A. humile Schott, A. medium (Zoll. & Moritzi) Nicolson and A. zippelianum (Schott) Nicolson. The last three species are found in Indonesia whereas the first two species occurs in Vietnam and China. Amydrium humile is found restrictly in Sumatera and Malay Peninsula and considered rare in the wild due to habitat loss by human activities. Bearing no flowers on its climbing shoot A. humile is unique among other member of the genera. The species is collected from Regist 9B Seminung, Mount Lumbok Seminung Protected Forest, West Lampung Regency and cultivated in Bogor Botanic Gardens. "

"The genus Huperzia is an epiphitic fern of the family lycopodiaceae which has potential value as an ornamental plant. However, information on its usage, cultivation, and conservation aspects are still limited. Bogor Botanic Garden as an ex-situ conservation institution plays an important role in conserving the genus. Exploration activities have been done in many places in Indonesia. Until now, Bogor Botanic Garden has collected several specimens from North and West Sumatra and Maluku."

"ABSTRAKSyzgium pycnanthum belongs to Myrtaceae family. This species is potential for oranmental plant because the flower and the fruit are very attractive and also the canopy structure looks interesting, especially for garden plant. Purwodadi Botanic Garden has collected some specimens of this species mostly from East Java."

"Kontribusi emisi gas rumah kaca, yakni karbondioksida (CO2) dan terutama methane (CH4) dari ekositem lahan basah (wetlands) termasuk yang terbesar. Interaksi antara tipe vegetasi, factor abiotik, dan pegolahan lahanadalah penting dalam perhitungan fluks karbondioksida dan methana dari suatu ekosistem. Dalam penelitian ini, pengukuran terhadap fluks gas karbondioksida, metahana, karakter tanah, kelembapan udara dan suhu serta komposisi vegetasi di ekosistem rawa pasang surut asin (salt marsh) dan rawa payau (brackish marsh) dilakukan di pulau Terschelling, Belanda. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi tumbuhan model pengelolaan (a.l. penggembalaan/grazing atau pembabatan/mowing) terhadap emisi gas karbondioksida dan methana dari ekosistem rawa. Komposisi vegetasi di dua tipe rawa berbeda. Keragaman jenis dipengaruhi oleh kegiatan pengembalaan; jumlah jenis di tapak rawa payau yang mengalami penggembalaan adalah 39 jenis sedangkan yang tidak mengalami penggembalaan adalah 31 jenis. Fluks karondioksida di rawa asin hampir sama besarnya dengan yang ada di rawa payau. Fluks methana rawa asin lebih rendah dibandingkan fluks methane rawa payau. Di daerah rawa payau, penggembalaan meningkatkan emisi gas methana."

"Areal konservasi yang didedikasikan untuk koleksi dan pertukaran bahan tanaman disinyalir menjadi sumber gulma bagi wilayah di sekitarnya. Tujuan dari penelitian ini adalah mengindentifikasi dan mengevaluasi gulma ruderal invasif di Kebun Raya Bogor (KRB). Observasi dilakukan untuk mengidentifikasi spesies gulma, menentukan tingkat invasif, dominasi gulma, dan penyebarannya di dalam KRB. Gulma diamati pada setiap vak (petak) termasuk asosiasinya dengan tanaman koleksi. Data pengendalian gulma dan kematian tanaman koleksi dianalisis kaitannya dengan keberadaan gulma. Penyebaran gulma di luar areal KRB diamati secara transek mengikuti alur sungai dan jalan raya. Hasil menunjukkan bahwa terdapat tujuh gulma invasif yaitu Cecropia adenopus (Cecropiaceae), Cissus nodosa Blume (Vitaceae), Cissus sicyoides Blume (Vitaceae), Dioscorea bulbifera L. (Dioscoreaceae), Ficus elastica Roxb. (Moraceae), Mikania micrantha H.B.K. (Asteraceae) dan Paraserianthes falcataria (L.) Nielsen (Fabaceae). Ketujuh gulma tersebut menginvasi pada 41 famili dari total 215 famili yang ada di KRB. Enam spesies yaitu C. adenopus, C. nodosa Blume., C. sicyoides Blume., D. bulbifera L., M. micrantha H.B.K. dan P. falcataria (L.) Nielsen pada awalnya adalah koleksi introduksi di KRB sedangkan F. elastica Roxb. merupakan spesies asli setempat. Ada dugaan kuat bahwa penyebaran gulma invasif di KRB karena pengaruh angin, burung, kelelawar, pengunjung dan aliran air. Semua gulma yang ada, juga ditemukan di luar areal KRB. Mengingat pengaruh gulma tersebut terhadap tanaman koleksi di KRB cukup merugikan, oleh karena itu, perlu ada langkah pengendalian jangka panjang yang komprehensif terhadap gulma tersebut baik di dalam maupun di luar kawasan KRB dengan melibatkan otoritas setempat.

"ABSTRAKCissus sicyoides L. is one of climber plant of Vitaceae and originally comes from Tropical Afrika. This is climber plant and become weed in Bogor Botanical Garden because their population growing very fast and invasive to other plant collection. C. sicyoides grows climbing up and covering the crown of some trees then hampering the process of photosintesis, flowering and fruiting of host plant. "

"Amorphophallus borneensis is endemic species from Kalimantan, belongs to the Araceae family. It is included as one of the giant Amorphophallus. This species is indicated by the unique pattern of the petiole and peduncle which resembles the comple patterns of lihen on the stem. The distribution of A. Borneensis was only known from soutern of Kalimantan. The new localities have been found during Kebun Raya exploration in Central and East Kalimantan."

"ABSTRAKLodoicea maldivica (J. F. Gmel) Pers. is a unique plant with the largest seed in the world. This is an endemic species to the Seychelles in Africa. Categorized as vulnerable plant, L. maldivicia get lost of threats. Ex situ conservation has been done in a number of Botanic Garden including Bogor Botanic Garden. The Bogor Botanic Garden has a female collection of L. maldivica and artificial pollination has been conducted using the male flower from Singapore Botanic Garden. This artificial pollination has been succesfully done and now the plant are bearing 3 fruits. "
