Abstract

Taro is a promising food crop that can be developed as a significant source of carbohydrates; however, a major obstacle is the unavailability of high-quality planting materials. Due to the difficulty in obtaining seeds, taro cultivation generally relies on vegetative propagation materials such as cormels, cormlets, and stolons. The advantage of using vegetative propagation material is that it retains the same characteristics as the parent plant. This research aimed to evaluate the quality of various types of cormels as taro planting material, study the potential of different types of cormels on the growth and production of taro plants, and investigate the growth, development, and time required to produce cormels from various types of cormels and their potential in cormel seed production. The research consisted of two experiments: the first experiment evaluated the quality of several types of cormels from two taro accessions (S24 and S28) using a completely randomized design with two factors (accession and types of cormels—primary, secondary, and tertiary), while the second experiment studied the growth and development of cormels from various types of cormels. The best quality seeds were obtained from primary cormels directly attached to the main tubers, with the germination rate highest for primary cormels at 53.25%, followed by secondary cormels at 51.59%, and tertiary cormels at 39.42%. Accession S24 showed a faster emergence rate (30.26 days) compared to S28 (58.08 days), and in S24, there was no significant difference between types of cormels for this parameter. In contrast, in S28, primary cormels had a significant emergence advantage (33.65 days) over secondary and tertiary cormels (62.57 and 78.02 days, respectively). Additionally, primary cormels were formed 8 weeks after planting, while secondary and tertiary cormels appeared 12 weeks after planting. These findings suggest that primary cormels should be prioritized for use in taro propagation to improve growth, development, and yield, highlighting their potential in cormel seed production and offering a viable solution to the challenge of seed availability in taro cultivation.

Abstract

Subang merupakan salah satu penghasil beras terbesar di Indonesia sehingga kebutuhan akan benih padi yang bermutu sangat mendesak dengan jumlah yang besar. Namun, penyimpanan benih-benih padi yang digunakan masih dilakukan dengan cara tradisional yang mampu menurunkan kemampuan fisiologis benih yang akan digunakan sebagai bahan tanam. Hidropriming merupakan salah satu cara sederhana untuk meningkatkan mutu fisiologis benih padi sehingga tetap memiliki nilai viabilitas dan vigor yang tinggi ketika akan ditanam. Penelitian ini bertujuan untuk meningkatkan mutu fisiologis benih yang diukur dalam pengukuran viabilitas dan vigor benih padi. Metode yang digunakan adalah Rancangan Acak Kelompok dengan dua perlakuan yaitu varietas benih padi IPB 3S (V1) dan Cibatu (V2) serta empat taraf hidropriming yaitu H0 = kontrol, H1 = perendaman air, H2 = perendaman air kelapa 25%, H3 = perendaman air kelapa 75%. Penggunaan air kelapa sebagai metode hidropriming dengan konsentrasi 25% secara umum memiliki kemampuan terbaik untuk meningkatkan mutu fisiologis benih padi berdasarkan parameter daya berkecambah, potensi tumbuh maksimum, indeks vigor, keserempakan tumbuh hingga berat kering kecambah normal.

Abstract

Brown rice is dehulled rice that retains its bran layer and therefore has higher fiber and nutrient content than white rice. Germination and instant processing are applied to improve the quality of brown rice and shorten cooking time. This study aimed to evaluate the effects of soaking duration (12 and 24 h) and germination time (36, 48, and 60 h) on the physical and chemical properties of instant rice produced from germinated brown rice (GBR) of the Inpari-32 variety, using a nested randomized block design. Variables for GBR included yield, radicle emergence, moisture content, ash content, and amylose content, while instant rice was evaluated for bulk density, yield, moisture content, ash content, and amylose content. Data was analyzed using ANOVA followed by DMRT at the 5% significance level. Results showed that soaking and germination duration had no significant effect on GBR yield or amylose content of instant rice, whereas germination time significantly affected GBR moisture and ash content, which ranged within national quality limits. The resulting instant rice had low bulk density, acceptable moisture content, and relatively high ash (mineral) content. A combination of 12 h soaking and 36 h germination is recommended as an efficient treatment to produce instant rice from GBR with acceptable physical and chemical quality.
