Abstract

Penelitian ini bertujuan untuk mengetahui peran mikoriza pada semai A. auriculiformis dalam menghadapi cekaman salinitas dan mengetahui tingkat salinitas yang dapat ditoleransi semai A. auriculiformis yang diinokulasi mikoriza. Hasil penelitian menunjukkan bahwa semai yang diinokulasi jamur endomikoriza dan diberi cekaman salinitas memiliki kandungan  P dan N lebih tinggi daripada semai yang tidak diinokulasi pada taraf salinitas yang sama tetapi pada konsentrasi yang makin tinggi kadar P dan N mulai menurun. Kandungan K lebih rendah pada semai yang diinokulasi daripada semai yang tidak diinokulasi pada taraf salinitas yang sama begitu juga pada semai yang tidak diberi cekaman salinitas. Tingginya salinitas tanah pada media tumbuh berpengaruh positif terhadap infeksi jamur endomikoriza pada akar semai A. auriculiformis. Serapan Na pada semai yang tidak diinokulasi cenderung lebih tinggi daripada semai yang diinokulasi. Hal ini menunjukkan bahwa jamur endomikoriza membantu semai A. auriculiformis dalam menahan Na di akar agar tidak terangkut ke bagian pucuk.

Abstract

The purpose of this study was to determine the effectiveness of AMF types on the increasing growth of Lonkida (Nauclea orientalis L.) plants under salinity stress conditions. This study was carried out in the plastic home of the Indonesian Mycorrhizal Association Southeast Sulawesi branch, Kendari City and Forestry Laboratory, for five months, march - July 2019. This study used a Factorial Completely Randomized Design consisting of 3 replications and three plant units. The first factor included treatment without AMF, Acaulospora sp1. and Clorideglomus etunicatum. The second factor includes Salinity 0 mM, 50 mM, 100 mM, 150 mM and 200 mM. The results showed that the interaction of AMF and salinity was not effective in increasing plant growth. Inoculation of AMF type C. etunicatum can increase height, plant dry weight, root shoot ratio, seed quality index, and root colonization. N. orientalis has a high dependence on arbuscular mycorrhizal fungi. Giving 0 mM salinity increases height, diameter, number of leaves, plant dry weight, and seed quality index

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

ABSTRACT Samama (Anthocephalus macrophyllus) is a wood-producing tree with fast growth. Arbuscular mycorrhizal fungi status (AMF) can associate well with samama plants. This study aimed to determine the diversity of the genus and the number of spores of AMF in the rhizosphere of the samama plant, which has different soil types and environmental factors. The method used to obtain AMF spores was a wet filter pour and centrifugation technique at the center for plant seeds and plant protection for two months. Based on the research results in the village of Poka, it was found that there were four AMF genera with a total of 235 spores. Hatusua village found two genera of FMA with a count of 141 spores. In the village of Uraur, three genera of FMA were found with 479 spores. AMF spore production is influenced by the type of fungus and temperature, sunlight, soil pH, aeration, and water. The presence of mycorrhizae can increase soil fertility as a biological agent.
