Mutation techniques through gamma ray irradiation is useful to support breeding programs for genetic improvement of wheat. Genetic improvement on tolerance to high temperatures is necessary for development of wheat in Indonesia. The purpose of this study was to determine the level of radiosensitivity to be used as the basis for the induction of mutations by gamma ray irradiation on embryogenic callus to obtain putative mutants with high temperature tolerance. Explants used were embryogenic callus cultured on MS medium containing 30 g L-1 sukrosa, 2 g L-1 gelrite, 2 mg L-1 2.4D and 1 mg L-1 picloram. Culture incubated for 6 weeks with temperature 20±4 oC in the room culture. Five irradiation doses (10, 20, 30, 40 and 50 Gy) were used in radiosensitivity testing. A factorial, completely randomized design was applied to the experiment. The first factor was selection temperature with three levels (25, 30 and 35 oC), and the second factor was doses of gamma ray iradiation with three levels (10, 20, and 30 Gy). The result showed that radiosensitivity levels varied among varieties, LD20: 7.79 to 18.96 Gy and LD50: 24.29-33.63 Gy. Selayar variety which has highest sensitivity value compared with Dewata and Nias. Increasing doses of iradiation and temperature decrease survival of embryogenic callus, number of embryos, and percentage of germinated plantlets. Based on in vitro selection using high temperature (25, 30, and 35 oC), the obtained 19 putative mutants were derived from embryos that appear on the surface of embryogenic callus survival after irradiation and high temperature selection.Keywords: in vitro selection, putative mutant, radiosensitivity, somatic embryo

Nilam (Pogostemon cablin Benth.) merupakan tanaman penghasil minyak atsiri potensial di Indonesia. Tingginya permintaan minyak nilam tidak diikuti oleh produksinya. Produktivitas nilam yang rendah salah satunya disebabkan oleh kurangnya ketersedian bibit bermutu. Salah satu metode alternatif perbanyakan bibit unggul dalam waktu relatif singkat dapat dilakukan melalui kultur jaringan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian beberapa konsentrasi zat pengatur tumbuh Benzile Amino Purin (BAP) terhadap multiplikasi tunas nilam secara in vitro. Penelitian telah dilaksanakan pada bulan Maret sampai Mei 2022 di Laboratorium Kultur Jaringan Departemen Agronomi, Fakultas Pertanian Universitas Andalas, Padang. Penelitian disusun berdasarkan rancangan acak lengkap dengan konsentrasi BAP sebagai perlakuannya yang terdiri dari empat taraf, yaitu 0 ppm; 0.5 ppm; 1 ppm dan 1.5 ppm pada media MS (Murashige dan Skoog). Hasil penelitian menunjukkan bahwa konsentrasi BAP sebanyak 0.5 ppm merupakan perlakuan terbaik yang mampu menghasilkan tunas sebanyak 134.6 tunas.

The community service took place for the Women Farming Group (WFG) of Banda Langik in the Sungai Bangek, Balai Gadang, Koto Tangah District, Padang City, from July to November 2022. It was held in demonstration plots (dump lots) of Liquid Organic fertilizers (LOF) with coconut coir, and banana stems as raw materials. These raw materials were straightforward to find in this area. Plots were made of 2 beds, and each was planted with pull-out Kale from seeds. Each bed was divided into two parts: without LOF and given LOF. It helped the WFG members differentiate the growth and yield pull-out Kale between being given LOF and without LOF. LOF was made by fermenting coconut coir separately and banana stems in a closed bucket for two weeks. The fermented products were sprinkled on the plants every week, starting at the age of two weeks after planting until they were close to harvest. The results showed that the plants given LOF were higher than those without LOF. The plant has given LOF more leaves. Their length and width of leaves were more significant than those without LOF. LOF is very useful given to vegetable plants, especially pull-out Kale.

Coconut plants are an important commodity for Indonesian people. In the cultivation process, coconut plants need a suitable environment for growth and production. One of the problems in cultivation is weeds. Weeds have a negative impact on cultivated plants, therefore appropriate control measures are needed. So far, the most effective weed control is chemical methods using herbicides. One of the herbicides that can be used is the herbicide with isopropyl amine glyphosate 165 SL. The aim of the experiment was to determine the efficacy of the herbicide isopropyl amine glyphosate 165 SL for controlling weeds in coconut cultivation was conducted from February to June 2022 at Pariaman City, West Sumatra Province. The experimental units were laid out according to a Randomized Block Design with 7 treatments and 3 groups as replications. The treatment was herbicide isopropyl amine glyphosate 165 SL at doses of 3.50 l ha-1, 5.25 l ha-1, 7.00 l ha-1, 8.75 l ha-1, 10.00 l ha-1, manual weeding and control (without weeding). The results of the research show that (1) The herbicide isopropyl amine glyphosate 165 SL can generally control weeds in coconut cultivation up to 12 weeks after application because the weed biomass in the treatment plot is relatively the same as manual weeding and is lighter than the control; (2) Herbicide isopropyl amine glyphosate 165 SL with a dose range of 3.50 l/ha – 10.50 l ha-1 up to 6 weeks after application does not show symptoms of phytotoxicity in coconut plants.

Plant breeding programs need to be carried out in order to improve the genetics of wheat that is able to adapt to tropical environments through hybridization, mutation induction, tissue culture, and genetic transformation. In vitro culture through somatic embryogenesis pathways plays an important role in genetic improvement and its integration with other breeding programs can positively affect the improvement of wheat quality, quantity, and development in Indonesia. The purpose of this study was to obtain an embryogenic callus induction method from the Dewata variety using five different types of explants, namely mature Seeds, immature embryos, immature seeds, leaf, stem, and to obtain combination of plant growth regulators and putrescine on somatic embryogenesis of wheat. The experimental design was prepared based on a complete randomized design with a combination treatment of embryogenic callus induction media consisting of 9 levels, namely: 1 ppm 2.4- D, 1 ppm 2.4-D + 1 ppm Picloram, ppm 2.4-D + 1 mg / L Picloram, 1 ppm 2.4-D + 10-4 M Putrescine, 1 ppm 2.4-D + 1 ppm Picloram +10-4 M Putrescine, 2 ppm 2.4-D + 1 ppm Picloram + 10-4 M Putrescine, 1 ppm 2.4 D + 10-3 M Putrescine, 1 ppm 2.4 D + 1 ppm Picloram + 10-3 M Putrescine, 2 ppm 2.4 D + 1 ppm Picloram + 10-3 M Putrescine. The results showed that the media used was able to induce embryogenic callus using mature seed and immature embryo, but immature seed and leaf were not able to produce embryogenic callus. The best media that produced the highest percentage of embryogenic callus was 2 ppm 2.4-D + 1 ppm Picloram + 10-4 M Putrescine with as much as 85.9% in young embryo explants.

Soybean (Glycine max L.) is a type of nutritious food crop because soybean seeds have high protein amino acid content. Increasing domestic production for soybean self-sufficiency needs to be done by expanding the planting area. The objective of this research is to examine the effect of ethyl methane sulfonate concentration and obtain soybean plants tolerant to drought and aluminum stress through in vitro selection. This research was conducted from November 2023 to January 2024 at the Tissue Culture Laboratory, Faculty of Agriculture, Andalas University. The research was arranged in a Completely Randomized Design consisting of 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 induced by EMS mutation and 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 not induced by EMS mutation with 3 replications. Data analysis was performed using independent sample t-test at a significance level of 5% and interpreted descriptively. The results showed that mutation induction using ethyl methane sulfonate (EMS) did not produce soybean somatic embryo mutants tolerant to drought and aluminum stress. Meanwhile, results from non-mutated callus produced somatic embryos suspected to be potential putative somaclonal candidates tolerant to drought and aluminum after double in vitro selection using 10% PEG 4000 and 150 ppm AlCl3 selection agents.

The corpse flower (Amorphophallus titanum Becc.) is an endemic flora of Indonesia that is naturally found only in Sumatra. The status of A. titanum is endangered because of several factors: deforestation, tuber exploitation, long flowering time, and protogyne. Until now, there has been no research about the population and distribution of A. titanum in West Sumatra. This study aimed to obtain information about the population and distribution of A. titanum in West Sumatra, so this research is essential to learn. The research used roaming and snowball sampling methods in Solok Selatan and Sijunjung Regencies in September-October 2022. The research was conducted by recording the coordinates where A. titanum was discovered, marked using GPS, and collecting morphological characteristics. The results showed that exploration in the Solok Selatan District found 19 corpse flower individuals (18 species of A. titanum and one species of A. gigas). In contrast, exploration in Sijunjung Regency managed to found 25 species of A. titanum. The corpse flowers found were in vegetative, dormant, flowering, and fruiting phases. The results help record the number and distribution of A.titanum in West Sumatra. The ex-situ conservation program will use germplasm as propagation material in the future.
