Abstract

Melon (Cucumis melo L.) is a high-value horticultural commodity with increasing market demand, but its productivity is constrained by the limited availability of superior varieties and a dependence on imported seeds. This study evaluated the morphological and agronomic characteristics of two net-type melon lines, Fitotech 2 and Fitotech 3, compared with commercial varieties Alina and Amanda. The research was conducted in Cikarawang Village, Bogor, from October 2024 to January 2025, employing a single-factor Randomized Complete Block Design (RCBD) comprising four treatments with three replications each, with 180 plants observed.. Data were collected based on qualitative and quantitative traits, then analyzed using Analysis of Variance (ANOVA), followed by the Honestly Significant Difference (HSD) test at the 5% significance level. Cluster analysis was performed using the average linkage method and Euclidean distance with Minitab software version 22.2.0. The results showed that Fitotech 2 has the highest sugar content (13.78°Brix), a powerful net pattern, uniform round fruit shape, ideal fruit size, and attractive fruit color. Fitotech 3 has the largest stem diameter (0.89 cm), high sugar content (13.44°Brix), optimal flesh thickness (3.09 cm), bright orange flesh color, a powerful net pattern, and a round fruit shape that aligns with market preferences.

Abstract

In rice, germination and early seedling growth are significantly influenced by seed viability. Viability is decreased by seed deterioration during storage, especially in older seeds. The purpose of this study was to ascertain how soaking time and potassium nitrate (KNO₃) concentration affected the germination and viability of old rice seeds (Oryza sativa L.) of the Inpari-32 variety. KNO₃ concentrations (0%, 1%, 2%, and 3%) and soaking times (24, 30, and 36 hours) were the two elements that determined the experiment's Completely Randomised Design (CRD). The percentage of normal seedlings, aberrant seedlings, vigour index, germination percentage, and non-germinated seeds were among the parameters noted. The results indicated that KNO₃ concentration significantly increased germination, with the highest percentage of normal seedlings obtained at 3% KNO₃ showing an increase of (48.33%) compared to the control and followed by 2% KNO₃ with an increase of (47.77%), compared to the control (32.22%). The length of the soaking period had a significantly significant impact; 36 hours produced the highest germination percentage (59.58%), followed by 30 hours (47.30%) and 24 hours (15.90%). There was no discernible relationship between the amount of KNO₃ and the length of soaking. While longer soaking times improved water imbibition and triggered physiological processes, the administration of KNO₃ increased seed metabolic activity. In conclusion, old rice seeds' viability and vigour were successfully increased by KNO₃ concentrations of 2-3% and a 36-hour soaking period; however, the improvement was insufficient to reach a high vigour category.

Abstract

Jambu air var. Cincalo Weha merupakan plasma nutfah tanaman lokal yang berasal dari Desa Gondrong, Provinsi Banten. Jambu ini memiliki potensi ekonomi untuk dikembangkan, namun tidak diimbangi dengan ketersediaan bibit jambu air yang berkualitas. Kultur jaringan merupakan salah satu alternatif penyediaan bibit yang seragam, bebas penyakit dan dalam jumlah besar. Penelitian ini bertujuan untuk mengetahui efektivitas penyinaran dan ZPT (2,4-D dengan BAP) dalam menginduksi kalus daun jambu air var. Cincalo Weha secara in vitro. Rancangan percobaan yang digunakan Rancangan Petak Terbagi dengan Rancangan Acak Kelompok sebagai rancangan dasar, ulangan 4 blok dan terdiri dari 2 faktor. Faktor pertama adalah penyinaran: 16 jam (L1) dan 24 jam (L2). Faktor kedua adalah ZPT (2,4-D dan BAP): (tanpa 2,4-D dan BAP) (K0); (2,4-D 1 mg/L + BAP 0,5 mg/L) (K1); (2,4-D 2 mg/L + BAP 0,5 mg/L) (K2); dan (2,4-D 3 mg/L + BAP 0,5 mg/L) (K3). Hasil penelitian menunjukkan bahwa perlakuan penyinaran tidak berpengaruh terhadap diameter kalus dan luas kalus. Sedangkan, perlakuan ZPT (2,4-D 2 mg/L + BAP 0,5 mg/L) memberikan hasil terbaik pada parameter diameter kalus umur 8 MST (1,05 cm) dan 10 MST (1,24 cm), serta luas kalus umur 8 MST (1,16 cm2) dan 10 MST (1,47 cm2).

Abstract

Manggis Macakal merupakan salah satu varietas unggul yang berasal dari Provinsi Banten. Penelitian ini bertujuan untuk mengetahui pengaruh kadar konsentrasi 2,4-D dan BAP terhadap induksi kalus embriogenik manggis (Garcinia mangostana L.) var. Macakal secara in vitro. Penelitian ini dilaksanakan di Laboratorium Bioteknologi Universitas Sultan Ageng Tirtayasa, Serang, Provinsi Banten pada bulan Juni-Oktober 2023. Penelitian menggunakan rancangan acak kelompok lengkap, terdiri dari dua faktor dan empat ulangan. Faktor pertama adalah konsentrasi 2,4-D (P) yang terdiri dari dua taraf yaitu: 1 ppm (P1) dan 2 ppm (P2). Faktor kedua adalah konsentrasi BAP (R) yang terdiri dari tiga taraf yaitu: 0,5 ppm (R1), 0,75 ppm (R2), dan 1 ppm (R3). Hasil penelitian menunjukkan bahwa perlakuan 2,4-D tidak memberikan pengaruh nyata terhadap diameter kalus, luas kalus dan pertumbuhan kalus embriogenik. Perlakuan BAP memberikan hasil terbaik terhadap diameter kalus pada umur 12 MST (0,79 cm). kemudian luasan kalus pada umur 12 MST (0,97 cm2).
