Abstract

Determination of D. crumenatum mutant obtained from in vitro mutation breeding needs a long time due to its long-life cycle. SSR molecular markers can be used for early mutant detection. Specific SSR markers developed in D. crumenatum are not yet available. Alternative published SSR markers were developed from D. catenatum. The aims of this study are to screen the most informative SSR markers generated from D. catenatum tested in irradiated D. crumenatum population and to determine the gamma irradiation dose resulting the most mutants. Ten SSR markers were randomly selected and tested in 25 individuals of D. crumenatum plantlets irradiated with several doses (0, 5, 10, 15, and 20 Gy; 5 plantlets each dose). The result showed 7 of 10 primers were polymorphic and the other three were  monomorphic. All seven polymorphic primers can be used to identified intraspecific variation in the D. crumenatum mutant population. Markers dnsr28 and dnsr98 were the most informative, with the highest polymorphic information content (PIC) value of 0.5. Irradiation D. crumenatum protocorms using 10-15 gray doses were detected as the highest mutant percentage obtained up to 100% in the sample tested. This resulting marker information can be used to screen wider mutant population to decrease the non-mutant individuals in the population for maintenance and cost efficiency. The 10-15 Gy can be used as reference doses for gamma irradiation in 3 months old D. crumenatum protocorm materials.

Abstract

The large number of in vitro media circulating in the market is a challenge to find the most effective media for sachinoka strawberry meristem culture, because the need for in vitro media depends on genetic intelligence. The purpose of this study was to find the best media from the various tested media to reproduce the Sachinoka variety strawberry seedlings in a relatively short time using the meristem culture method. This study used a completely randomized design (CRD) with 6 media treatments and repeated 7 times, namely: M1 (WPM without BA), M2 (WPM + 4 ppm BA), M3 (NP without BA), M3 (NP + 4 ppm BA), M5 (BMM without BA), M6 (BMM + 4 ppm BA). The variables observed were the time of emergence of shoots, the number of shoots and the number of leaves. The results of this study indicate that there is no significant difference for the emergence of shoots variable. Treatment M1 produced the highest number of shoots (12.29) but not significantly different from M5 (10.14), both were significantly different from both treatments. The highest number of leaves is in M1 (27.14). It can be concluded that the best medium for the growth of sachinoka strawberry meristem culture is WPM media with the addition of 4 ppm BA, while the second-best medium is BMM media with the addition of 4 ppm BA.

Abstract

The effect of inoculation of a combination of the arbuscular mycorrhizal fungus of Glomus and Acaulospora on micropropagated banana plantlets cultivar Raja from Bali during the acclimatization phase was investigated. The experiment was conducted at the Experimental Station of the Faculty of Agriculture, Udayana University, Denpasar, Bali, Indonesia, over the period of March to June 2022. The objective of this research was to evaluate the impact of various doses of mycorrhizae on the growth of tissue culture banana plantlets that had undergone acclimatization for a period of six weeks. A total of five different doses of mycorrhiza were applied to the acclimatized plantlets, namely M0=without mycorrhiza and M5=5g mycorrhiza.kg-1, M10=10 g mycorrhiza.kg-1, M15=15 g mycorrhiza.kg-1, M20=20 g mycorrhiza.kg-1. A significant effect was discovered at M15; however, compared to M20, M20 gave better results for root length and fresh weight of the above-ground part, indicating the best dose was 20 g mycorrhiza kg-1. This study concluded that mycorrhiza has a very significant role in supporting the growth of micro propagated banana plantlets at post-acclimatization. Variables observed, such as the average number of leaves, stem diameter, above-ground plant fresh and dry weight, and root fresh and dry weight, increased with the application of AMF (Glomus and Acaulospora).

Abstract

The Ratna flower (Gomphrena globosa L.), commonly known as globe amaranth, is widely used as an ornamental plant, natural tea ingredient, food coloring, and traditional medicine due to its various health benefits. In Bali, this flower also holds important cultural value as an offering in ceremonies and sacred dances. Despite its diverse uses, studies on the morphological and phytochemical diversity of G. globosa accessions across different growing regions remain limited. This study aimed to characterize the morphological traits and analyze the phytochemical composition of pink-flowered Ratna accessions collected from two regions, Sibanggede and Padang Galak. The research was conducted from October to December 2023. Sampling areas were determined using an exploratory method with purposive sampling, and plant samples were collected using a simple random sampling approach. The findings revealed distinct morphological variations in leaf and stem surfaces between accessions from the two locations. Phytochemical analysis showed qualitative and quantitative differences in chemical composition. The Sibanggede accession contained major compounds such as phytol, ethyl ester, and hexadecanoic acid—known for their antioxidant, anticancer, and antibacterial properties. In contrast, the Padang Galak accession was dominated by compounds including 2(4H)-Benzofuranone and thiourea, which exhibit antiarthritic and anticancer activities. These morphological and phytochemical differences are likely influenced by environmental factors affecting plant development and secondary metabolite synthesis. Overall, this study provides baseline information for the cultivation and utilization of Ratna flower in pharmaceutical, cosmetic, and ethnobotanical applications.

Abstract

Trichoderma merupakan salah satu mikroorganisme spesifik spesies, jadi masing-masing spesies Trichoderma akan memberikan pengaruh yang berbeda terhadap spesies tanaman yang berbeda. Penelitian ini dilakukan dengan tujuan untuk mengetahui Pengaruh Penambahan Trichoderma spp. Pada Media Tanam Terhadap Pertumbuhan Bibit Pisang (Musa acuminata) Cavendish Hasil Kultur Jaringan. Penelitian ini menggunakan rancangan percobaan satu faktor dengan rancangan lingkungan RAL. Trichoderma ditambahkan dengan perbedaan spesies Trichoderma yaitu T0 = Kontrol, Ta = T. asperellum., Th= T. harzianum, Tk = T. koningii, Tv = T. viride. Tahapan penelitian aklimatisasi plantlet tahap satu (3 minggu), inkubasi Trichoderma pada kompos (2 minggu), aklimatisasi tahap dua (6 minggu). Data yang diperoleh dari pengukuran, penghitungan dan pengamatan variabel dianalisis secara statistik dengan menggunakan analisis of variance (ANOVA). Hasil analisis ANOVA menunjukkan bahwa aplikasi Trichoderma spp. pada tanaman pisang (Musa Acuminata) cavendish hasil kultur in vitro berpengaruh tidak nyata P ≥ 0,05 terhadap semua variabel yang diamati. Namun ada kecenderungan pertambahan jumlah helai daun Th lebih banyak 1,75 helai dibanding T0, panjang akar Th lebih panjang 6,525 cm dibanding T0.

Abstract

Vanda tricolor Lindl. var. suavis is an Indonesian wild orchid which is now extremely rare in nature due to its habitat destruction. Development of an appropriate method for improving Vanda orchid through genetic modification could be valuable for horticulture and, indirectly, also for conservation. In this research, a method of Agrobacterium-mediated transformation of two V. tricolor obtained from Salak Mount, West Java and Merapi Mount, Yogyakarta in Indonesia protocorms was improved using acetosyringone (AS). Concentrations of 0 and 25 ppm AS were used in transformation of pG35S binary vector containing kanamycin resistance geneinto V. tricolor protocorms. The result showed that 25 ppm AS was required on inoculation with Agrobacterium solution, without AS on cocultivation. Five weeks after treatment on the 300 ppm kanamicyn containing medium, green protocorms were obtained, that was 11.01% for V. tricolor from Salak Mount with pre-culture treatment prior to inoculation, 9.39% for V. tricolor from Merapi Mount with pre-culture treatment prior to inoculation, and 1.37% for V. tricolor from Merapi Mount without pre-culture treatment prior to inoculation. The best condition to set high efficiency of transformation is pre-culture protocorms prior inoculation, soaking protocorm on 25 ppm AS for 30 minutes, then co-cultivate its on AS-free callus induction medium.
