Abstract

Titan arum (Amorphophallus titanum Becc.) is an endemic species of Indonesia that is found naturally only in Sumatra and is classified as endangered, with an estimated 303 mature individuals remaining in their natural habitat. The population is decreasing due to deforestation, tuber exploitation, long flowering times, and protandry. Therefore, both in-situ and ex-situ conservation programs are necessary to preserve this species. The research aims to explore natural populations, analyze habitat conditions, develop propagation methods, and conduct reintroduction efforts to support the conservation of A. titanum. This study was conducted from 2023 to 2024 in Palupuah, Agam Regency, the Agriculture Faculty of Universitas Andalas, and several locations for the reintroduction of A. titanum. The research found that A. titanum habitat consists of forests rich in humus and litter, as well as banana cultivation areas. During the exploration, 7 individuals were identified: one in dormancy, one fruiting, and 5 in the vegetative phase. Seed germination experiments categorized seeds into seven classes based on their weight. The most dominant seed class weighed between 2.9 g and 3.2 g, comprising 38 seeds or 26.9% of the total. The germination rate and seedling growth were high, as all seeds exhibited 100% and produced seedlings of relatively uniform size. Propagation was carried out using in vitro culture techniques with petiole explants. The results showed that 2 mg L-1 benzyl aminopurine (BAP) successfully induced callus formation with a 100% induction rate, while a concentration of 1.5 mg L-1 achieved the highest shoot induction rate at 58.3%, with an average of 1.3 shoots and 7.9 roots per explant. The propagated seedlings were subsequently replanted in several locations for reintroduction activities.

Abstract

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.

Abstract

Kantong semar (Nepenthes ampullaria Jack.) merupakan spesies endemik yang tersebar di Sumatera dan Kalimantan. Spesies ini berstatus least concern karena minimnya data penelitian terbaru mengenai kelimpahan dan penyebarannya. Eksploitasi untuk perdagangan dan deforestasi menyebabkan penurunan populasi. Selain itu, waktu yang lama untuk mencapai fase generatif dan tipe pembungaan dioecious juga berkontribusi terhadap penurunan populasi Nepenthes sp. Program konservasi baik in situ maupun ex situ sangat penting untuk menjaga kelestarian N. ampullaria. Perbanyakan tanaman melalui setek dapat mendukung kegiatan konservasi. Keberhasilan setek ditentukan oleh konsentrasi zat pengatur tumbuh (ZPT) untuk menginduksi pembentukan akar dan tunas, sehingga kajian tentang konsentrasi ZPT penting untuk dipelajari. Penelitian ini bertujuan untuk menentukan konsentrasi IBA terbaik untuk menginduksi akar dan tunas pada N. ampullaria. Penelitian disusun berdasarkan rancangan acak lengkap dengan perlakuan konsentrasi IBA yang terdiri dari 5 taraf yaitu: 0, 5, 10, 15, dan 20 mg L-1. Hasil penelitian menunjukkan bahwa konsentrasi IBA tidak berpengaruh nyata terhadap pertumbuhan stek pucuk N. ampularia dengan persentase hidup setek berkisar 70-100 %, pertambahan tinggi tunas berkisar 5.01-9.53 cm, jumlah akar primer berkisar 5.89-9.56 helai dan jumlah akar primer berkisar 3.52-6.29 cm. Semua perlakuan mampu meransang terbentuknya akar dan tunas yang mengindikasikan bahwa kandungan fitohormon endogen telah mencukupi untuk pertumbuhan setek pucuk pada N. ampullaria.

Abstract

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.

Abstract

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

Abstract

Titan arum (Amorphophallus titanum (Becc.)) was an endemic flora found only on the island of Sumatra, listed as endangered and possessing the largest flower among 170 species of Amorphophallus. Conservation activities could benefit from the use of plant propagation through cuttings. The success of cuttings was determined by the concentration of plant growth regulators (PGR) to induce the formation of roots, corms, and shoots, making the study of PGR concentration important. This study aimed to find the best IBA concentration to induce roots, corms, and shoots in A. titanum. The research was conducted from February to October 2023. The study was designed based on a completely randomized design with treatments of IBA concentration consisting of 5 levels: 0, 5, 10, 15, and 20 mg L-1. The results showed that an IBA concentration of 15 mg L-1 produced the best survival percentage (100%), rooting percentage (93.33%), corm formation percentage (93.33%), shoot formation percentage (76.67%), and an average of 1.20 shoots per cutting on A. titanum petiole cuttings.

Abstract

Stunting in children under five remains a significant public health issue in Indonesia, particularly in West Sumatra, where prevalence rates exceed the national average. Addressing this challenge requires improving nutritional intake, focusing on essential micronutrients like zinc (Zn) and iron (Fe). Biofortification is a promising agricultural strategy to enhance the nutritional quality of staple crops such as rice. This study aims to explore and evaluate the Zn and Fe content of local rice genotypes from West Sumatra, which hold potential for biofortification programs.Twenty-eight rice genotypes, including 27 local genotypes and one control (Inpari Nutri Zinc), were analyzed for Zn and Fe content. The results showed that the control variety, Inpari Nutri Zinc, exhibited the highest Zn (31.30 ppm) and Fe (19.85 ppm) content. Among the local genotypes, Puluik Mutia (Zn: 28.40 ppm, Fe: 18.30 ppm), Kuning Aro (Zn: 27.60 ppm, Fe: 18.20 ppm), and Rampai Kuning (Zn: 26.20 ppm, Fe: 18.05 ppm) displayed the highest Zn levels, while Manggung (Fe: 18.85 ppm) had the highest Fe content. These findings highlight the significant variability in micronutrient content among local genotypes, emphasizing their potential as germplasm for biofortification breeding programs.This research represents the first systematic exploration of Zn and Fe levels in local rice genotypes from West Sumatra. The novelty lies in identifying high-Zn and Fe genotypes, particularly those with firm texture preferences, which could support biofortification efforts and provide a sustainable solution to combat stunting. Future research should focus on environmental interactions and agronomic practices to further optimize the micronutrient content in local rice varieties
