VARIASI MORFOLOGI KABAU (ARCHIDENDRON BUBALINUM) DAN PEMANFAATANNYA DI SUMATRA Dewi Komariah; Alex Hartana
Floribunda Vol. 5 No. 5 (2016)
Publisher : PTTI

Dewi Komariah & Alex Hartana. 2016. Morphologycal Variation and Use of Kabau (Archidendron bubalinum) in Sumatra. Floribunda 5(5): 157–164. — The strong flavour and taste of kabau (Archidendron bubalinum) seeds are somewhat similar to jering (Archidendron jiringa) and petai (Parkia speciosa) seeds, so that they are used to flavour food. Since very little is known about its biology, the result of a study on its utilization and the morphological variability of kabau in Sumatra is presented. Stems, leaves, flower, fruits, and seeds were observed from 28 plants of kabau, collected from Jambi, South Sumatra, and Lampung. Those morphological data were analyze using UPGMA with NTSyspc 2.11a version. The result showed that kabau plants clustered into two groups based on 20 morphological characters.Keywords: kabau, morphology, Sumatra, UPGMA, utilization.Dewi Komariah & Alex Hartana. 2016. Variasi Morfologi Kabau (Archidendron bubalinum) dan Pemanfaatannya di Sumatra. Floribunda 5(5): 157–164. — Rasa dan aroma yang kuat dari biji kabau (Archidendron bubalinum) menyerupai rasa dan aroma biji Jengkol (Archidendron jiringa) dan petai (Parkia speciosa), sehingga ketiganya digunakan sebagai penambah rasa makanan. Informasi biologi tentang kabau masih sangat sedikit, hasil penelitian tentang pemaanfaatan dan variasi morfologi kabau di Sumatra disajikan dalam penelitian ini. Batang, daun, bunga, buah, dan biji diamati dari 28 tumbuhan kabau yang dikoleksi dari Jambi, Sumatra Selatan, dan Lampung. Data morfologi dianalisis menggunakan UPGMA dengan NTSyspcversi 2.11a. Hasil penelitian menunjukkan kabau terpisah menjadi dua kelompok berdasarkan 20 karakter morfologi.Kata kunci: kabau, morfologi, pemanfaatan, Sumatra, UPGMA.

VARIASI MORFOLOGI ANDALIMAN (ZANTHOXYLUM ACANTHOPODIUM) DI SUMATRA UTARA Romaita Newanti Lumban Raja; Alex Hartana
Floribunda Vol. 5 No. 7 (2017)
Publisher : PTTI

Romaita Newanti Lumban Raja & Alex Hartana. 2017. Morphologycal Variation of Andaliman (Zanthoxylum acanthopodium) in North Sumatra. Floribunda 5(7): 258–266. — Andaliman plants (Zantoxylum acanthopodium DC.) found in North Sumatra, Indonesia, and known as seasoning plants or 'merica Batak’ in Batak dishes. This study was conducted to explore the diversity of andaliman plants in North Sumatra. 27 andaliman plants collected and analyzed based on their 24 morphological characters of stems, leaves, flowers, fruits, and seeds using unweighted pair group method with arithmatic average (UPGMA) and clustered based on similarity for qualitative data (SIMQUAL) and coefficient simple matching, using NTSYS pc. 2.02 version. The phenetic analysis showed dendrograme of 27 andaliman plants in North Sumatra were clustered into 4 groups. The main characters differentiate each group are the color of young branches, thorns on leaf midrib, the color of calyx, and the color of fruit. The group I and II in dendrograme refer to local cultivar names ‘Simanuk’ and ‘Sihorbo’, while the group III and IV refer to ‘Silokot’ and ‘Sikoreng’ cultivars. An identification key for the four andaliman cultivars is presented. Keywords: Andaliman, Character, Clustering, North Sumatra, Morphology, Zantoxylum acanthopodium. Romaita Newanti Lumban Raja & Alex Hartana. 2017. Variasi Morfologi Andaliman (Zanthoxylum acanthopodium) di Sumatra Utara. Floribunda 5(7): 258–266. — Andaliman (Zantoxylum acanthopodium DC.) di Indonesia banyak terdapat di Sumatra Utara dan digunakan sebagai bumbu masakan khas suku Batak. Eksplorasi keberagaman andaliman telah dilakukan dan diperoleh 27 nomer sampel. Analis fenetik berdasarkan 26 karakter morfologi terhadap 27 sampel telah dilakukan dengan metode UPGMA melalui program NTSys versi 2.02. Dendrogram yang dihasilkan menunjukan ada 4 kelompok andaliman yang terpisah berdasarkan karakter utama yang membedakan setiap kelompok yaitu warna dahan muda, rambut pada dahan, onak pada ibu tulang daun, warna kelopak bunga, dan warna buah. Berdasarkan klasifikasi masyarakat, kelompok I dan II merujuk pada kultivar ‘Simanuk’ dan ‘Sihorbo’. Sedangkan kelompok III dan IV merujuk pada kultivar ‘Silokot’ dan ‘Sikoreng’. Hasil pengelompokan kemudian digunakan untuk pembuatan kunci identifikasi.Kata kunci: Andaliman, karakter, pengelompokan, Sumatra Utara, morfologi, Zantoxylum acanthopodium.

Petai tersebar di Indonesia termasuk di Sumatra bagian Tengah. Keanekaragaman petai di wilayah ini belum banyak diungkapkan. Penelitian ini mengamati keanekaragaman morfologi petai yang tersebar di Sumatra bagian Tengah. Sampel dikoleksi dari 9 lokasi di provinsi Sumatra Barat, Riau, dan Jambi. Sebanyak 29 aksesi tumbuhan petai (ZH1-29) diamati 38 ciri morfologinya, selanjutnya dilakukan analisis fenetik menggunakan metode Unweighted Pair group method with arithmetic average (UPGMA). Hasil penelitian menunjukkan Petai dari wilayah ini tersusun atas dua jenis yaitu Parkia singularis Miq. dan P. speciosa Hassk. Petai bervariasi pada 9 ciri penting yaitu bentuk ujung dan pangkal anak daun; panjang tangkai polong; bentuk dan ukuran polong; jumlah biji per polong, jarak antar biji, jarak biji ke tepi polong, dan ketebalan kulit. Analisis keserupaan mengelompokan semua aksesi petai jenis P. speciosa dan memisahkan dari jenis P. singularis. P. speciosa dikelompokkan lebih lanjut sesuai dengan kultivar lokal yang dikenal masyarakat. Dua kultivar lokal memiliki ciri unggul yaitu Petai Papan dan Petai Papan1. Kunci dan deskripsi dari masing-masing nama lokal petai disediakan.

Pulasan is an androdioecious plant that has both male and hermaphrodite flowers on separate plants. The objectives of this study were to obtain data about the anatomical structure of pulasan flower and to investigate whether the pistil and the stamens of pulasan flower reach maturity at different times. The anatomical observation was done on compound flowers taken from three male trees and three hermaphrodite trees. Two compound flowers that still in buds, about to bloom and fully bloom were picked from each tree. Flowers were observed in a cross and longitudinal section. The results showed that the sepals of pulasan flower comprised of the uniseriate epidermis and multilayered polyhedral parenchymal cells. Stamen development started from the anther followed by the formation of the filament. The pollen of hermaphrodite pulasan flowers reached maturation earlier than the pistil. The pistil development started from the expansion of meristem cells in the center of the flower and ends with the warp of the stigma.
