Abstract

ABSTRACTPolynesian arrowroot (Tacca leontopetaloides (L.) Kuntze), which is one of the bulbous herbaceous plants,have high nutritional value. Modification of macro nutrients by reducing nitrogen content and increasingphosphorus on the medium gave affects on shoot growth and initiated micro tuber formation on in vitrocultures. The aim of this research was to determine the effect of modified macro nutrients in combination withthe increase in sucrose concentrations on shoot growth and micro tuber formation of T. leontopetaloides. Theexperimental design was factorial completely randomized design.The factors tested were modifications of MSmacro nutrients that were. M1 (170 mg/l KH2PO4 and 1650 mg/l NH4NO3; normal, control treatment); M2 (340mg/l KH2PO4 and 825 mg/l NH4NO3); and M3 (680 mg/l KH2PO4 and 412.5 mg/l NH4NO3 in combinationwith 30 (S1) (control treatment), 40 (S2), 50 (S3) and 60 g/l of sucrose (S4). The variables tested were shootheight, number of leaves, number of roots and number of micro tuber which were observed weekly at 0-8weeks after culturing. The results showed that the modification of macro nutrient in combination with sucroseconcentration had significant effect on shoot height, number of leaves and number of roots but not significanton the number of tubers. The highest shoots were found in M1S3 treatment, the highest number of leaves wasin M1S1 and M1S3 treatment and the highest number of roots was in M1S4 treatment. The number of tubersnot significantly different between the treatments tested.Keywords: in vitro, KH2PO4, microtuber, NH4NO3, sucrose, Tacca leontopetaloides

Abstract

Physic nut (Jatropha curcas Linn.) has the potential as a source of sustainable biofuels. Somatic embryo proliferation of J. curcas may cause somaclonal variations. This research aimed to investigate somaclonal variations of J. curcas somatic embryo derived-plantlet using ISSR markers. Somatic embryos of J. curcas at the globular phase were cultured on liquid MS medium supplemented with 0, 0.5, 1.0, 1.5, and 2.0 mg L-1 of 2,4-D. Parameter observed were embryos weight, embryos volume, colour, and size of embryos. After proliferation, the embryos were cultured on a germination medium until the cotyledonary phase. The results showed that proliferation of J. curcas somatic embryos was optimal, with the highest weight and volume,  at MS medium added with 1 mg L-1 2,4-D.

Abstract

ABSTRACT Propagation of sempur (Dillenia philippinensis Rolfe) using conventional vegetative methods is considered ineffective due to slow process and low germination level. Propagation by tissue culture is considered more effective because it does not depend on the season and requires less plant material. It can benefit sempur conservation since it is categorized as threatened with extinction in 2020 on the IUCN red list. This study aimed to evaluate the effect of BAP and NAA on the growth of sempur’s shoots and to observe the morphology of shoot culture. The media used as a control was MS without growth regulators. The treatment medium was MS with the addition of BAP and NAA. Shoots were used as explants. Shoot growth and plantlet morphology were observed eight weeks after planting. The results indicated that the combination of 1 mg/l BAP and 0.5 mg/l NAA resulted in the highest total number of leaves, nodes and adventitious shoots. The combination of BAP and NAA, each 1 mg/l, resulted in the highest fresh weight and callus formation. The combination of 1 and 2 mg/l BAP and 0.5-1 mg/l NAA could not form roots. In comparison, the combination of BAP and NAA in culture media could change the shape and size of the leaves. The survival rate of growth of plantlets derived from MS medium was 50% at 22 weeks after acclimatization.Keywords: morphology, shoot culture, sempur, BAP (Benzil Amino Purin), NAA                  (Naphthalene Acetic Acid) ABSTRAK Perbanyakan tanaman sempur (Dillenia philippinensis Rolfe) dengan metode konvensional secara vegetatif memerlukan waktu lama dan daya kecambah biji juga rendah. Perbanyakan dengan kultur jaringan dianggap lebih menguntungkan karena tidak tergantung musim, memerlukan sedikit bahan tanaman dan bermanfaat untuk konservasi sempur karena termasuk spesies yang hampir terancam punah tahun 2020 dalam daftar merah IUCN. Penelitian ini bertujuan untuk mengevaluasi pengaruh BAP dan NAA terhadap pertumbuhan tunas sempur serta mengamati morfologi kultur tunas. Media yang digunakan sebagai kontrol adalah MS yang tidak mengandung zat pengatur tumbuh. Media perlakuan adalah MS dengan penambahan BAP dan NAA. Tunas pucuk dipergunakan sebagai eksplan. Pertumbuhan tunas dan morfologi planlet diamati pada delapan MST. Hasil pengamatan menunjukkan bahwa kombinasi 1 mg/l BAP dan 0,5 mg/l NAA menghasilkan jumlah total daun, buku dan jumlah tunas adventif tertinggi. Kombinasi BAP dan NAA masing-masing 1 mg/l menghasilkan bobot basah dan pembentukan kalus tertinggi. Kombinasi antara BAP 1 dan 2 mg/l serta NAA 0,5-1 mg/l tidak mampu membentuk akar. Kombinasi BAP dan NAA pada media kultur mengubah bentukan dan ukuran daun.  Daya tumbuh planlet yang berasal dari media MS adalah 50% pada 22 minggu setelah aklimatisasi.  Kata kunci: morfologi, kultur tunas, sempur, BAP (Benzil Amino Purin), NAA                   (Naphthalene Acetic Acid)

Abstract

Bawang putih (Allium sativum L.) cv. Doulu merupakan bawang putih lokal yang berasal dari Desa Doulu Kabupaten Simalungun, Sumatera Utara, Indonesia. Secara konvensional, A. sativum cv. Doulu diperbanyak melalui umbi sehingga kurang efektif karena rentan hama dan penyakit. Alternatif perbanyakan bibit A. sativum cv. Doulu dapat dilakukan melalui pembentukan kalus embrio somatik secara in vitro untuk memproduksi bibit tanaman yang seragam, bebas hama penyakit, stabil dan dapat diproduksi dalam waktu yang relatif singkat. Penelitian ini bertujuan untuk mengetahui pengaruh jenis eksplan A. sativum cv. Doulu yang dikultur pada media DKW dengan penambahan zat pengatur tumbuh BAP dan picloram terhadap pembentukan kalus embrio somatik secara in vitro. Rancangan percobaan yang digunakan adalah Rancangan acak lengkap faktorial dengan faktor pertama yang diuji yaitu jenis eksplan (daun, bonggol, akar) dan faktor kedua yakni konsentrasi zat pengatur tumbuh (0; 0.5; 1; 2 dan 3 mg L-1 BAP dan Picloram). Parameter yang diamati yakni, jumlah quadran eksplan membentuk kalus, diameter kalus, bobot kalus dan volume kalus. Hasil penelitian menunjukkan bahwa eksplan bonggol dan akar A. sativum cv. Doulu mampu membentuk kalus lebih baik dibandingkan dengan eksplan daun. Pemberian zat pengatur tumbuh BAP dan picloram dengan konsentrasi 0.5 dan 3 mg L-1 secara signifikan meningkatkan pertumbuhan kalus A. sativum cv. Doulu, yang terlihat dari tingginya nilai diameter kalus, bobot kalus, dan volume kalus yang terbentuk. Pada perlakuan tanpa penambahan zat pengatur tumbuh BAP dan Picloram (kontrol) tidak terbentuk kalus. Kata kunci: BAP, bawang putih Doulu, embrio somatik, induksi kalus, Picloram.
