“…The plant height, number of leaves, and size of the leaf of tetraploid taro plants also displayed smaller than the diploid ones. In several species of plants, it is known that tetraploid plants generally have larger plant sizes (plant height, leaves, and flowers), such as, moringa (Ridwan and Witjaksono, 2020), hydrangea (Deans et al, 2021), caladium (Zhang et al, 2020), and ginger (Zhou et al, 2020). However, in some species of plants, tetraploid plants have smaller leaf sizes, such as, watermelon plants (Bae et al, 2020), slower growth in eucalyptus plants (Fernando et al, 2019), and lower fresh and dry weight in rubber dandelion plants (Taraxacum kok-saghyz) (Luo et al, 2018).…”

“…Past studies enunciated the use of oryzalin to induce polyploid on the taro cultivar Bentul (Wulansari et al, 2017) and the use of colchicine with Kaliurang cultivars in Indonesia (Ermayanti et al, 2018). Induction of polyploidy in a plant could affect growth and morphological, anatomical, phytochemical, and agronomic characteristics (Corneillie et al, 2019;Mo et al, 2020;Ridwan and Witjaksono, 2020;Wulandari et al, 2020).…”

Taro (Colocasia esculenta L. cv. Pontianak) is a popular and widely cultivated cultivar in the Indonesian farming community. In taro Pontianak, manipulating the ploidy level by chromosome doubling can enhance its genetic diversity. The latest study aimed to evaluate the oryzalin-induced polyploid taro cv. Pontianak compared with its diploid in terms of growth, anatomical, cytological, morphological, and agronomic traits in the greenhouse and the field. In vitro shoots of taro cv. Pontianak were soaked using a liquid medium supplemented with oryzalin with a concentration of 30 and 60 μM for one day. After five times of subcultures, flow cytometry analysis proceeded to determine their ploidy levels. The diploid (2n = 2x) and tetraploid (2n = 4x) plantlets were then acclimatized in the greenhouse for six to eight weeks and hardened for two months before planting in the field for 10 months. Squashing the root tip to ensure the ploidy levels of taro seedlings helped measure the chromosome numbers. Observing the growth, anatomical, and agronomic traits of diploid and tetraploid plants occurred during the hardening process until harvest time. The 30 μM oryzalin treatment produced tetraploid and mixoploid shoots; none from the 60 μM treatment. Oryzalininduced tetraploid taro exhibited some morphological characteristics of tetraploid plants, such as, longer stomata size and low density. Tubers of tetraploid plants tended to have increased protein, ash, and water content compared with their diploid counterpart. However, tetraploid taro showed a slower growth rate both in the greenhouse and the field. Additionally, it gave lower yields than diploids in some agronomic characteristics, including delayed flowering time, lower plant fresh weight, and smaller tubers. This study provides information that oryzalin-induced tetraploid taro could exhibit increasing and decreasing nutritional-agronomic traits (as mentioned above) compared with its diploid.

“…Masyarakat Bangka Belitung mengenal umbi kemili dengan sebutan tanaman kemili. Tanaman umbi kemili merupakan salah satu sumber komoditas pangan pertanian yang tumbuh subur di negara yang beriklim tropis dan sub tropis, tetapi tanaman ini belum banyak diketahui oleh masyarakat indonesia, hanya sebagian penduduk di pulau Jawa, Bali, Sumatera dan Madura (Ridwan et al, 2016). Tanaman kemili ini masih belum populer di kalangan masyarakat Bangka Belitung sehingga kandungan di dalam umbi kemili belum termanfaatkan oleh masyarakat untuk kebutuhannya.…”

Tanaman kemili merupakan tanaman pangan alternatif yang tumbuh subur di negara Indonesia. Namun, tanaman kemili sampai saat ini belum populer di kalangan masyarakat Bangka. Penelitian ini bertujuan untuk mengetahui keanekaragaman aksesi kemili (Solanostemon rotundifolius) di Kabupaten Bangka berdasarkan karakter morfologi dan mengetahui hubungan kekerabatan antar plasma nutfah kemili berdasarkan morfologi di Kabupaten Bangka. Penelitian dilakukan pada bulan Januari sampai Juni 2021. Penelitian ini menggunakan metode eksperimen. Pengambilan sampel dilakukan secara eksplorasi di Kabupaten Bangka dan dikarakterisasi secara kualitatif dan kuantitatif. Hasil penelitian ditemukan ada 3 aksesi yang terdapat di Kabupaten Bangka, yaitu aksesi Balunijuk, Kimak, dan Batu Rusa. Terdapat 2 kelompok hubungan kekerabatan berdasarkan morfologi dengan koefisien 0,65 atau 65%. Aksesi kemili yang diteliti memiliki variabilitas genetik dan variabilitas fenotipik yang sempit. Kemili plants are an alternative food commodities that thrive in Indonesia. Kemili plants aren’t yet popular among the people of Bangka. The aim of the study was to determine the diversity of accessions of the kemili (Solanostemon rotundifolius) in Bangka Regency based on morphological characteristics and to determine the relationship between the germplasm of the Kemili (Solanostemon rotundifolius) based on morphology in Bangka Regency. The research was conducted from January to June 2021. The study used an experimental method. Sampling was taken by exploration in Bangka Regency and characterized by qualitative and quantitative characters. The results of the study found that there were 3 accessions found in Bangka Regency, namely Balunijuk, Kimak, and Batu Rusa. There are 2 groups of morphological relationships with qualitative characters with a coefficient of 0.65 or 65%. Kemili accession have narrow genetic variability, and phenotypic variability.

Abstract. Ridwan, Hamim, Suharsono, Hidayati N, Gunawan I. 2021. Drumstick (Moringa oleifera) variation in biomass and total flavonoid content in Indonesia. Biodiversitas 22: 493-500. Utilization of a drumstick (Moringa oleifera Lam.) leaf has recently increased worldwide which consequently cause the increase in global demand. Indonesia, as a tropical country with large area, has a great potential to become a center for drumstick cultivation and leaf production. Drumstick distribution scattered in almost all of the islands of Indonesia has another potential for obtaining superior genotype variabilities. The aim of this study was to select the drumstick accessions from several islands in Indonesia with high leaf biomass production and flavonoid content. This experiment was carried out in the field using ten accessions of drumstick from ten islands in Indonesia, namely Sumatra, Java, Madura, Bali, Lombok, Sumbawa, Sumba, Kalimantan, Sulawesi, and Papua. Drumstick seeds were planted in polybags with a capacity of 10 kg and arranged using a randomized block design with three replications. The parameters observed were plant growth, biomass production, total flavonoid content, and antioxidant activity. The results of this study found that Sumatra accession was the accession which had the highest leaf biomass production in combination with the uppermost total flavonoid content and antioxidant activity compared to others. Sumatra accession is recommended as an excellent accession for cultivation with the aim of producing flavonoids.
