Abstract

ABSTRACT The purpose of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the salibu method, and to get the best concentration of gliricidia liquid organic fertilizer  (POC) on the growth and production of lowland rice. Field research has been conducted in Tababo Village, Subdistrict of Belang, district of Southeast Minahasa. The treatment in the experiment consists of one treatment factor, that were concentrations of gliricidia POC, ie  : 0, 50 , 100, 150, and 200 ml/litre. The results showed that gliricidia POC  have an effect on plant height, the number of  grain/panicle, and the dry grain yield (GKP) / plot, but not affect the number of productive tillers and weight of 1,000 grain. The best results were achieved in gliricidia POC concentration 200 ml/litre  with the highest values were: plant height was 98.93 cm; 116.420 grain/panicle; and 8.300 kg dry grain yield or equivalent to 6.92 ton/ha.Keywords : gliricidia POC, production, lowland rice,  salibu method

Abstract

Metode identifikasi spesies telah disepakati menggunakan barcode DNA standar yaitu gen rbcL dan gen matK. Tujuan penelitian ini untuk menentukan tingkat kemiripan sekuens barcode DNA tanaman Anggrek Payus Limondok (Phaius tancarvilleae) dengan spesies kerabatnya yang sudah terdata dalam BOLD Systems, merekomendasi penggunaan barcode untuk mengidentifikasi atau mengkonfirmasi spesies ini, dan mengamati variasi intraspesifik. Teknik Polymerase Chain Reaction (PCR) digunakan untuk mengamplifikasi sekuens gen rbcL dan matK melalui primer universal. Barcode rbcL menunjukkan kemiripan 100% (identik) dengan dua spesies berbeda dalam famili yang sama (Orchidaceae), sehingga tidak bisa diandalkan untuk identifikasi spesies P. tancarvilleae secara akurat. Sekuens matK sampel menghasilkan kemiripan 100% dengan spesies sama yang sebelumnya telah terdata dalam BOLD Systems. Kemiripan ini mengindikasikan rendahnya variasi genetik intraspesies tetapi sekuens matK dapat diandalkan untuk identifikasi atau konfirmasi spesies anggrek P. tancarvilleae.Kata Kunci: barcode, rbcL, matK, Phaius tancarvilleae AbstractSpecies identification methods convention have been recommended to use standard DNA barcode for plants; the rbcL and matK genes. The aims of this research were to determine similarities in barcode DNA sequences of Payus Limondok Orchid (Phaius tancarvilleae) with its close relatives that listed in BOLD Systems, to recommend the use of DNA barcodes for identification or confirmation of this species, and to observe intraspecific variations. Polymerase Chain Reaction technique was employed to amplify rbcL and matK genes using universal primers. The rbcL barcode of Payus Limondok resulted identical hit with other two different species in the same family (Orchidaceae), therefore, unreliable for accurate P. tancarvilleae species identification. The matK sequence of this plant was 100% similar with the same plant species listed in BOLD Systems. This similarity indicated low genetic variation within the species, but the matK sequence was found to be reliable for P. tancarvilleae orchid species identification or confirmation.Keywords: barcode, rbcL, matK, Phaius tancarvilleae

Abstract

AbstrakMetode standar untuk identifikasi spesies tumbuhan melalui barcode DNA telah direkomendasikan untuk menggunakan dua gen plastida yaitu rbcL dan matK. Tujuan penelitian ini yaitu untuk menentukan tingkat kemiripan sekuens barcode DNA tanaman Anthurium Gelombang Cinta (Anthurium plowmanii) dibandingkan spesies kerabatnya yang sudah terdata dalam BOLD Systems dan untuk merekomendasi penggunaan barcode DNA yang bisa diandalkan dalam mengidentifikasi spesies ini. Teknik Polymerase Chain Reaction (PCR) digunakan dalam perbanyakan sekuens fragmen gen rbcL dan gen matK oleh primer universal yang tersedia. Hasil penelitian menyimpulkan bahwa sampel tanaman A. plowmanii menghasilkan sekuens barcode rbcL yang mirip 100% (identik) dengan spesies A. cubense. Ini berarti barcode DNA rbcL tidak dapat digunakan untuk identifikasi tingkat spesies. Sekuens barcode matK sampel menunjukkan kemiripan 99,1% dengan A. ravenii yang berbeda dalam morfologi daun. Sekuens matK sampel bersifat unik diantara anggota-anggota genus Anthurium sehingga direkomendasikam penggunaannya untuk identifikasi sampai tingkat spesies.Kata Kunci: barcode, rbcL, matK, Anthurium plowmaniiAbstractStandard method for plant species identification through DNA barcode has been recommended to use two plastids genes; the rbcL and matK. The aims of this research were to determine similarities in DNA barcode sequences of Anthurium Wave of Love (Anthurium plowmanii) with its close relatives that listed in BOLD Systems and to recommend the reliable DNA barcode for identification of this species. Polymerase Chain Reaction was employed to amplify rbcL and matK genes fragments using available universal primers. The result showed that A. plowmanii sample was 100% similar to A. cubense. For that reason, the rbcL gene is not a reliable for species identification. Sequence of matK barcode showed 99.1% in similarity with A. ravenii which has different leaf shape. The matK sequence of sample was unique among all listed Anthurium members, therefore, this barcode are recommended for plant identification to the species level.Keywords: barcode, rbcL, matK, Anthurium plowmanii

Abstract

Abstrak Pengembangan tanaman kentang (Solanum tuberosum L.)  unggul untuk menunjang kebutuhan produksi kentang yang terus meningkat membutuhkan tersedianya informasi genetik tanaman kentang yang ada. Informasi keragaman genetik dapat diperoleh menggunakan penanda molekuler RAPD yang dapat mendeteksi keragaman sampai pada tingkat DNA, baik pada daerah penyandi atau bukan penyandi protein dengan cara mendeteksi polimorfik sekuens nukleotida. Informasi yang diperoleh akurat karena tidak dipengaruhi lingkungan.  Penelitian ini bertujuan untuk menganalisis keragaman genetik dari kentang kultivar Superjhon, Atlantik, Dessire, Nadia dan Granola menggunakan penanda RAPD.  Hasil penelitian menunjukkan bahwa dari 14 primer acak yang digunakan hanya 7 yang memberikan pola pita DNA yang polimorfik dan 16 pita dari total 28 pita DNA yang dihasilkan (57 %)  merupakan pita DNA polimorfik. Rata-rata keragaman genetik kentang sebesar 26,8 %. Keragaman genetik terkecil (15,4 %) adalah antara kentang  Atlantic dan Superjhon, sedangkan keragaman terbesar (57,7 %) antara kentang Nadia dan Dessire. Hasil analisis pengelompokan menunjukkan tanaman mengelompok berdasarkan sifat/karakter dan asalnya. Kata kunci: kentang, keragaman genetik, RAPD Abstract The information of potato genetic diversity are required to support the increasing potato demands in the superior potato production. The information of genetic diversity can be obtained using RAPD molecular marker. RAPD can detect the genetic diversity at the DNA level, both in the coding region and non-protein-coding regions by detecting polymorphic sequences in nucleotides. This method provide accurate genetic information because it is not influenced by the environment. This study was conducted to analyze the genetic diversity of potato Superjhon, Atlantic, Dessire, Nadia and Granola using RAPD marker. Amongst the 14 random primers, only 7 primers produced polymorphic banding pattern. Sixteen DNA bands of total 28 existed DNA bands (57%) were polymorphic. The average of genetic diversity was 26.8 %. The smallest genetic diversity (15.4%) was between Atlantic and Superjhon, whereas the greatest genetic diversity (57.7%) was between Nadia and Dessire. The analysis results showed that potato clustered grouping was based on their characters and their origins. Keywords: genetic diversity, potatoes, RAPD
