Abstract

The low production of true seed of shallot (TSS) is mostly caused by a low flowering rate. The research was aimed to increase the flowering rate and seed yield in lowland (240 masl) and highlands (1250 masl) by vernalization and submersion of the seed bulbs in GA3 before planting. The research was arranged in a completely randomized block design with 2 factors and replicated four times. The first factor was vernalization, i.e. without and with vernalization at 10±2°C for 30 days, and the second factor was the submersion of the seed bulbs following vernalization in GA3 at the concentrations of 0, 100, and 200 ppm for 1 h. Parameters measured were time of 50% flowering (days after planting), percentage of flowering plants, number of umbel per plant, number of floret per umbel, fruitset, seed weight per umbel and per plant, as well as the percentage of seed germination. The result suggested that when production of TSS of var. Bima is to be carried out in the lowland then the seed bulbs had to be vernalized at 10±2°C for 30 days which will increase the flowering percentage and seed yield. If the production of TSS is to be carried out in the highland then vernalization at 10±2°C for 30 days will increase the flowering percentage and seed yield. However, if for any reason vernalization is impossible to proceed then the submersion of the seed bulbs in 100 ppm GA3 for 1 h was sufficient to increase the flowering percentage and seed yield. The produced seeds (TSS) either in the low as well as in the highlands had high germination percentages. Keywords: germination, highland, lowland, umbel, true seed of shallot

Abstract

Ambon Forest nutmeg (Myristica fatua Houtt) is one of the endemic plants in Indonesia. The morphological characteristic of Ambon Forest nutmeg is slightly different from that of Banda nutmeg (Myristica fragrans Houtt) i.e., it is not used as spices, but its oil is used as a lamp oil. This study aimed to determine the chemical components and essential oils of Ambon Forest nutmeg derived from its seeds, mace, and flesh compared to Banda nutmeg. Extractions of essential oils were performed using a steam hydro-distillation. Analysis of chemical compositions and contents of essential oil was carried out using a Gas Chromatography-Mass Spectrometry (GCMS) instrument and SNI 06-2388-2006 method. The essential oil contents in Ambon Forest nutmeg were relatively low, i.e., 0.63% in the seeds, 0.30% in the mace, and 0.04% in the flesh compared to Banda nutmeg i.e., 1% in the seeds, 40% in the mace, and 3.5% in the fruit flesh. The chemical compositions of essential oils showed that M. fatua Houtt contained 12 compounds in the seeds, 24 compounds in the mace, and 17 compounds in the fruit flesh, while for Banda Nutmeg, the contents of essential oils were found 18 compounds in the seeds, 10 compounds in the mace, and 15 compounds in the fruit flesh. M. fatua Houtt contained the highest Copaene, i.e., 28.41% in the seeds, 10.42% in the mace, and 23.33% in the fruit flesh. Myristicin, as the main marker compound of nutmeg oil, was also found in Ambon Forest nutmeg i.e., 1.3% in the seeds, 1.16% in the mace, and 5.19% in the fruit flesh. However, these results showed lower contents when compared to Banda nutmeg with Myristicin contents of 8.72% in the seeds, 10.14% in the mace, and 10.46% in the fruit flesh. Keywords: Essential oil, Myristica fatua Houtt, Myristica fragrans Houtt, Nutmeg

Abstract

Abiu (Pouteria caimito Radlk.) is a plant of Sapotaceae family that can be consumed fresh, processed, or as a medical product. The fruit and leaves of this plant contain bioactive compounds. This research aims to inform the interaction between leaf:fruit ratio treatment and foliar fertilizer on the quality of the abiu fruit. The study was conducted at Kebun Balungbang Jaya, Dramaga, Bogor, West Java Province, from July 2022 to November 2022. The experiment used a factorial split plot design. The main plot was a leaf:fruit ratio treatment (N1, 45 leaves:1 fruit, and N2, 30 leaves:1 fruit) on each tertiary branch, and the tiller plot was foliar fertilizer (P1: 1 g L-1, P2: 2 g L-1, and P3: 3 g L-1), which consisted of 3 replications. The results showed that treatment of the leaf-fruit ratio and foliar fertilizer did not affect the quality of the abiu fruit. The interaction between leaf:fruit ratio and foliar fertilizer had a significant effect on ATT, as indicated by the lowest acidity value in the leaf:fruit ratio treatment of 45:1 and a fertilizer concentration of 1 g L-1 with a value of 0.12% but has no significant effect on the external and internal quality of other fruits. Keywords: Bioactive compounds, sapotaceae, tertiary branch, titratable acidity
