Abstract

Arbuscular Mycorrhizal Fungi (AMF) is a type of fungus that can form a symbiotic mutualism with most plants. Some AMF can only be symbiotic with a certain plant species. This research aims to determine and obtain the genus AMF from black cumin (Nigella sativa L.) accessions from America, Turkey, Hong Kong, Slovenia, India, and Kuwait accessions which had been grown in West Java, Indonesia. Three samples from each accession, four replications each, were collected for examination. The results showed that six generas of AMF were found in the rhizosphere of black cumin: Glomus, Gigaspora, Acaulospora, Scutellospora, Dentiscutata, and Entrophospora. The genus Glomus was predominantly found in the Indian accession, i.e. 96.42 spores.Keywords: black cumin, diversity, fungi, exploration, AMF

Abstract

Coleus atropurpureus L. Benth is a annual plant that has a distinctive leaf aroma and bitter taste. C. atropurpureus leaves contain phenolic compounds and antioxidants that can capture free radicals; free radicals play an important role in preventing various human diseases. A study was conducted to determine the correlation between leaf position (1st to 4th) at the vegetative and generative phases with leaf pigments, N, P, K, and total flavonoid concentrations. The results showed that leaf chlorophyll a, chlorophyll b, total chlorophyll, carotenoid, anthocyanin, nitrogen, and total flavonoids were higher in the vegetative phase. Therefore, C. atropurpureus is better harvested in the vegetative phase, and the 2nd leaf position can be used as indicator for N, K, pigments and total flavonoid content.

Abstract

Foot rot disease (Phytophthora capsica) is Indonesia's primary challenge in cultivating pepper (Piper nigrum). Grafting to another Piper species, Piper coclobrinum, or melada (the local name), is a potential solution to increase resistance to this disease. The use of melada as rootstock has shown promising results during the seedling phase, but it has not been thoroughly evaluated during the production phase. The study was conducted in the pepper grower’s location in Puput and Simpang Katis Villages, Central Bangka, Bangka Belitung Islands Province. The study used kapok (Ceiba petandra) as the standard; plant morphology, leaf area, leaf thickness, and crown diameter for grafted melada and non-grafted pepper were recorded. Harvest variables included panicle length, panicle weight, the number of fruits per panicle, and fruit diameter, measured in three different areas of the canopy: the lower area (0-1 meter above the ground surface), the middle area (1-2 meters above the ground surface), and the top area (more than 2 meters above the ground surface). Physiological variables measured included rates of photosynthesis, stomatal conductance, transpiration rate, intercellular CO2, and CO2 conductance. The study demonstrated that the grafted pepper plants had a larger leaf area than the non-grafted pepper plants; the panicle weight and the number of fruits per panicle were higher. Panicles located in the middle zone of the plant canopy tended to be longer for grafted and non-grafted peppers. Panicle weight, fruit size, and the number of fruits per panicle were generally more significant at the top of the plant canopy. In all parts of the canopy, grafted peppers exhibited larger fruit size, greater panicle weight, and a higher number of fruits per panicle than non-grafted “Nyelungkup” peppers, highlighting the potential of melada as a rootstock for pepper plants.

Abstract

This study investigated the effects of different shade levels and harvest ages on the growth, biomass yield, and essential oil production of the patchouli (Pogostemon cablin Benth.) cultivar Sidikalang, cultivated in a lowland environment. The experiment was conducted in Bogor from August 2023 to February 2024, using a nested design with three shade treatments (no shade, 55%, and 75%) and three harvest ages (4, 5, and 6 months). The results indicated that 75% shade significantly enhanced vegetative growth, including plant height, number of secondary branches, and leaf production, suggesting that this level of shading is beneficial for patchouli cultivation in lowland areas. However, these effects were not significantly different from those observed under 55% shade. The highest essential oil yields were obtained from patchouli plants grown under 75% shade and harvested at 4 months, as well as from those grown under full sunlight and harvested at 6 months.
