Abstract

Jatropha curcas L. is a potential source of a non-edible biofuel. Conventional propagation of J. curcas technique has some limitations. Somatic embryo can produce a large number of embryos and obtain a large number of plants all year round. Treatment of sucrose in combination with polyethylene glycol (PEG) was proven to enhance germination of somatic embryos in many plant species. The aim of the study was to investigate the effect of sucrose in combination of PEG on somatic embryo germination in J. curcas. Globular somatic embryos at 0.025-0.030 g fresh weight having 0.4-0.5 cm in diameter were grown on MS medium solidified with 3 g/l of Gelzan supplemented with sucrose at 20, 30, 40, and 50 g/l in combination with PEG at 0, 2.5, 5, 10, and 15%. Results showed that the best medium for germination of J. curcas somatic embryo cultures was MS medium supplemented with 20 and 30 g/l of sucrose in combination with 5% of PEG. The numbers of germinated embryos per clump had significant enhancement on those medium compared with the control (PEG free treatment) (2.65 to 5.65) and (2.55 to 5.50). In addition, those treatments resulted in the highest percentage of clumps forming germinated embryos (100%), with an average of normal germinated embryos at 94.163 and 96.065%. The addition of 40 and 50 g/l of sucrose in combination with 15% of PEG caused all embryos to fail at germinating.

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

The aim of this research was to compare the reduction effect of sucrose or table sugar concentration on growth characteristics of red ginger cultured in MS liquid medium. Shoots of red ginger was cultured on MS liquid medium without addition of plant growth regulators, supplemented with 5, 10, and 20 g/l of sucrose or table sugar for 8 weeks. Resulted plantlets were acclimatized in a greenhouse to investigate their growth and survival rate. Numbers of stomata, chlorophyll concentration as well as cross section of leaves from plantlets grown in vitro were compared to those of transplants grown in the greenhouse. The results showed that the use of table sugar at concentration of 20 g/l gave the best growth of red ginger. Meanwhile, the reduction of table sugar from 20 to 10 g/l reduced growth and survival rate of in vitro shoots as well as that of transplants in the greenhouse. Only few shoots formed roots when they were grown on the medium containing 5 g/l of table sugar, and transplants failed to grow in the greenhouse. It found that the chlorophyll content of in vitro plantlets was lower than those of transplants grown in the glasshouse. However, the number of stomata of the in vitro plantlets was higher than that of transplants grown in the glasshouse. There was no anatomical abnormalities found on the cross section of leaves between in vitro plantlets and transplants grown in the greenhouse. The replacement of sucrose with table sugar may reduce the production cost of plantlets.Keywords: red ginger (Zingiber officinale Rocs.), reduction of sugar, survival rate, chlorophyll, stomata.

Abstract

Article Highlight: Four accessions of Moringa oleifera from different regions in Indonesia were evaluated to identify with tolerance to aluminium (Al) stress Eight metabolites show a very high correlation with acetic acid (one of the metabolites associated with AlCl3 stress) including cyclopentene, 2-allyphenol, 4-ethynyl-6-8-dioxane, vinyl ether, ethanone 1-oxiranyl, 2-methylpyridine, 2-butanone, and ethanesulfonic acid. This research makes a significant contribution to understanding aluminium tolerance in oleifera by identifying tolerant accessions, clustering relevant traits, and highlighting key metabolites to in vitro culture. ABSTRACT Moringa oleifera Linn. has received substantial scientific interest due to its numerous bioactive compounds and its function as a nutritional resource. The absorption of aluminum by plants hinders several metabolic and physiological processes, leading to inhibited plant development and decreased agricultural output. Some accessions from different regions in Indonesia were evaluated to identify those with tolerance to aluminum (Al) stress. Al-tolerant selection was carried out in vitro through the selection method for Al stress by adding 0, 50, 100, 250, and 500 mg/L of AlCl3 to the media. Furthermore, identifying the metabolite profile of four M. oleifera accessions from four distinct regions in Indonesia: Blora, Bogor, Enrekang, and Bima, has been done using Py-GCMS. Specific metabolites associated with tolerance to Al stress and organic acids need to be identified. The highest survival rate was observed in the Bogor and Blora accessions when exposed to AlCl₃ at concentrations ranging from 0 to 250 mg/L, demonstrating greater tolerance to AlCl₃ than other accessions based on various variable, such as shoot height, number of shoots, number of petioles on a medium containing 100 to 250 mg/L of AlCl₃. The mean value was not statistically different from the control. Acetic acid was identified as one of the metabolites associated with AlCl₃ stress. A total of 21 metabolites were specifically correlated with acetic acid in a positive manner, among which 8 metabolites including cyclopentene, 2-allyphenol, 4-ethynyl-6-8-dioxane, vinyl ether, ethanone 1-oxiranyl, 2-methylpyridine, 2-butanone, and ethanesulfonic acid exhibited a very high correlation.

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.
