Abstract

Arbuscular mycorrhizal fungi (AMF) play a role in supporting the growth of various plants under certain conditions. AMF cannot survive in artificial media because they require a host plant for obligate symbiosis, which is necessary during the inoculum production process. The purpose of this study was to determine the effectiveness of corn and green bean roots as a breeding medium for arbuscular mycorrhizal fungi. The method used in this research used a two-factor completely randomized design (CRD). Observation of samples of the growth of corn and green bean seeds was carried out by observing samples placed on glass slides under a microscope. The results of the research showed that corn plants were more effective as a breeding medium for arbuscular mycorrhizal fungi (AMF) compared to green bean plants and the roots of corn plants were infected at a higher rate, namely 57.33% compared to the roots of green bean plants, namely 44.00%.

Abstract

The aim of this research is to determine and analyze the ability of agarwood plants to grow on inceptisol soil and to analyze the factors that determine the growth of agarwood plants on inceptisol soil in Hatusua Village, Kairatu District, West seram Regency. The method used in this research is a completely randomized design method, the data collection technique used in this research is in the form of direct observations carried out on a demonstration plot of the source of agarwood (Aquilaria malacccensis lamk) seeds from which 3 trees were taken from each provenance. And data analysis used a completely randomized design and multiple regression analysis. The results obtained from the research were variance analysis of parameters which showed that only the leaf bones were real. The three provenances are determined by three soil factors, namely fertility, humidity and pH. Of the three soil factors, only Laimu provenance has an influence, because it has a larger F-value. And the environmental factor that has the most influence on the Laimu provenance is atmospheric humidity, while the environmental factor that has the most influence on the Mornateng provenance agarwood plant is soil moisture and the most influential environmental factor for the Passo provenance agarwood plant is light intensity.

Abstract

Bacterial exploration aims to find out how endophytic bacteria associate with the roots of samama plants and find out the morphological characteristics of the endophytic bacteria found. So we can determine the type/family of endophytic bacteria on the Samama plant. Sampling of samama plants (Anthocepalus macropyllus) was taken on the campus of the Faculty of Agriculture, Pattimura University. The parts of the plant samples taken were roots, bark, leaf twigs and leaves. The number of tree samples taken as examples was 3 individual trees. Each plant organ sampled is 200 gr. The data analysis method used is by adjusting the data resulting from the identification of macroscopic and microscopic characteristics with the characteristics of bacterial families that are available according to references. Based on the results of this research, it can be concluded that: there are 9 isolates of endophytic bacteria, namely KB1 KB2 KB3 KB4 A1 A2 A3 A4 and B1 in the root, stem and bark tissues of Samama plants. Endophytic bacterial isolates Kb1, Kb2, kb3, kb4, A2, A4 have similar characteristics to the bacterial group of the genus Bacillus with the characteristics of rod-shaped cells and are classified as gram positive, while isolates Kb4, A2 and A4 have the characteristics of the genus Bacillus and have rod-shaped characteristics and classified as gram negative. Then isolate A1, A3, B1. It has similar characters to members of the coccus genus, namely round cells and is classified as gram positive, but the isolate code is classified as gram negative. The results of biochemical analysis show that samama plants have 3 types of bacteria, namely Bacillus altitudinis, Bacillus pumilus and Bradyrhizobium sp.

Abstract

Understory biomass plays an important role in maintaining forest ecosystem balance and the carbon cycle. This study aims to measure and compare understory biomass across various natural forest types in Hatusua Village, Maluku, namely Coastal Forest, Mangrove Forest, Dominant Aren Forest, and Lowland Forest. The method used includes systematic sampling with 2x2 meter plots, considering dense, moderate, and sparse conditions, where all understory plants were collected, weighed, and dried to estimate dry biomass. The results showed that the highest biomass was found in the Coastal Forest (2,716.14 kg/ha), followed by the Mangrove Forest (2,545.87 kg/ha), the Lowland Forest (1,841.72 kg/ha), and the lowest in the Dominant Aren Forest (1,629.33 kg/ha). This biomass variation is influenced by light intensity, soil conditions, and vegetation structure. Carbon content calculations based on biomass indicate that the Coastal Forest has the highest carbon storage, followed by the Mangrove Forest, Lowland Forest, and Dominant Aren Forest. This study confirms that understory biomass is a vital component of forest ecosystems, requiring attention in conservation efforts and climate change mitigation.

Abstract

Litter biomass is an essential component of forest ecosystems, playing a role in nutrient cycling, soil stability, and carbon storage. This study aims to measure and compare litter biomass across various types of natural forests in Hatusua Village, namely Coastal Forest, Mangrove Forest, Dominant Aren Forest, and Lowland Forest. The method used involved collecting litter samples from 2 × 2 meter plots, followed by drying and weighing to estimate dry biomass. The results showed that the highest litter biomass was found in Dominant Aren Forest (7,400.56 kg/ha), followed by Coastal Forest (5,773.71 kg/ha), Lowland Forest (1,798.55 kg/ha), and the lowest in Mangrove Forest (1,547.36 kg/ha). Differences in litter biomass among forest types were influenced by vegetation type, litter density, decomposition rates, and environmental conditions. This information is crucial for sustainable forest management and climate change mitigation through carbon storage in forest litter.

Abstract

This study aimed to determine the effect of biofertilizer containing endophytic bacteria from the roots of Indian almond trees (Terminalia catappa) on the growth and yield of lowland rice (Oryza sativa). The experiment used a completely randomized design (CRD) with three treatments: NPK fertilizer, endophytic bacterial biofertilizer, and a combination of both, each with three replications. Observed parameters included root dry weight, dry grain weight, and dry rice weight. The results showed that the endophytic bacterial treatment significantly increased all measured parameters compared to NPK and the combination treatments. Treatment A2 (endophytic bacteria) produced the highest values across all variables. These findings indicate that endophytic bacteria from the roots of Terminalia catappa have great potential as a biofertilizer to support sustainable and environmentally friendly rice cultivation.

Abstract

This study focused on the effect of endophytic bacteria from trees with wet habitats on the growth and productivity of lowland rice (Oryza sativa). Endophytic bacteria were obtained from root extracts of three plant species, namely kayu burung (bird's wood), forest catangensis (katapang hutan), and kayu marsegu (marsegu wood). Samples of the roots of kayu burung (bird's wood) and kayu burung (bird's wood) were collected from Ambon Island, while the roots of katapang hutan and kayu burung (bird's wood) came from Seram Island. The study used a descriptive method with field observations. Parameters observed included plant height, number of leaves, and dry grain weight per stem. The results showed that the highest average plant height was obtained in the treatment of endophytic bacteria from kayu burung (14.16 cm), followed by kayu marsegu (12.16 cm) and katapang hutan (10.16 cm). The treatment of endophytic bacteria containing Monococcus, Streptococcus, and Staphylococcus had a positive effect on vegetative growth and rice production. Endophytic bacteria from marsegu wood and forest catangensis produced the highest dry grain weight, namely 1.216 g per stem. These results demonstrate the potential of endophytic bacteria from forest plants as biological agents to increase rice productivity in lowland rice.
