Abstract

Arbuscular Mycorrhizal Fungi (AMF) is one of the fungi that forms a mutualism symbiosis with plants where there is a mutually beneficial relationship between the two parties and acts as a biological fertilizer that needs to be reproduced.AMF propagation is strongly influenced by the availability of nutrients, growing media and host plants. The purpose of this study was to determine the application of hormone growth booster fertilizer to increase the production of arbuscular mycorrhizal fungi spores.This research was conducted at the Plastic House of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch and the Laboratory of the Department of Forestry, Faculty of Forestry and Environmental Sciences, Halu Oleo University, Kendari during September – November 2022.This study was arranged based on a Completely Randomized Factorial Design. which consists of 2 factors. The first factor: AMF type which consists of two levels, namely Glomus coronatum and Glomus claroideum. The second factor: Fertilizer application consisting of three levels, namely without fertilizer application (B0), 2, and 5 ml/pot fertilizer (B2) with 3 repetitions. So there are 18 treatment combinations. Each treatment unit contained 9 plants so that the total number of plants was 162 plants. The results of this study indicate that the interaction treatment of G. coronatum and G. claroideum without fertilizer application can give the best results in increasing the number of spores for 3 months and in the treatment of G. coronatum with a fertilizer dose of 2, 5 ml gave the best results for increasing the number of spores after drying. Treatment of G. claroideum with a dose of 5 ml of fertilizer gave the best results in increasing the number of spores after drying.

Abstract

The aim of this work was to highlight the establishment of endomycorrhizal symbiosis in Intsia bijuga under certain conditions related to the presence of endomycorrhizal plants and show the effectiveness of symbiosis. The experiments were conducted at greenhouse. Single and dual cultivation of Intsia bijuga with each of the three different species of endomycorrhizal host plants (Zea mays, Crotalaria juncea and Dalbergia trichocarpa) on sterilized poor soil and forest soils (sterilized and unsterilized) were performed. On sterilized poor soil, the culture was inoculated by inoculums of endomycorrhizal fungi Glomus intraradices (syn. Rhizophagus irregularis). The effectiveness of the endomycorrhizal establishment was evaluated by the colonization of the roots by endomycorrhizae, the rate of Nitrogen and Phosphorus accumulated in leaves and plant mycorhizal dependency. Dual cultivation of Intsia bijuga with each of the three endomycorhizal host plants allowed endomycorhizal establishment in its roots and Intsia bijuga development was significantly improved by endomycorrhizal establishment. The biomass and the rates of N and P were significantly high in endomycorrhizal plants. Mycorrhizal dependency of Intsia bijuga in dual cultivation either with Crotalaria juncea or with Dalbergia trichocarpa (legumes) was lower than those with Zea mays. Endomycorrhizal symbiosis was effective in Intsia bijuga cultivated with endomycorrhizal host plants.

Abstract

Ultisol land is a physically and chemically poor piece of land because it needs special handling that must be done with extreme caution. Mikoriza Arbuskula fungi is one biological fertilizer technique to get around this issue. One of the tiny soil creatures that can coexist with the roots of land plants is the fungus Mikoriza Arbuskula. In order to support plant development and make it simpler for plants to absorb nutrients and maintain soil moisture, Mikoriza Arbuskula Fungi can symbiose with plant roots and form HIFA around young roots. The purpose of this study is: (1) to determine the effect of the application of the Mikoriza Fungi Arbuskula on increasing N-total and P-available on ultisol soil, (2) to determine the effect of the best Mikoriza Arbuskula Fungi application on the growth of eggplant in Ultisol. This research was conducted on experimental land II and the Laboratory of Ami Calay Sultra Faculty of Forestry University of Halu Oleo Kendari. The study was conducted in November - January 2023. This study used a group of randomized groups (shelves). Mushroom Mikoriza Arbuskula consists of 5 levels, namely M0 = without treatment, M1 = 5 g /polybag-1, M2 = 10 g / polybag-1, M3 = 15 g / polybag-1, M4 = 20 g / polybag-1. The results of the study show that the Mikoriza Arbuskula fungi affected the total increase in N and P-available ultisol soil, the results of the initial analysis of 0.03% increased to 0.13% and P available from 9.00 ppm increased to 17.50 ppm. Mikoriza arbuskula fungi with a dose of 20 g / polybag-1 provides better eggplant plant growth.

Abstract

The objective of this study was to determine the number of spores, root colonization and the type of AM Fungi in some agricultural plants in Oransbari District. Soil and root samples were collected across the agricultural land to isolate AM Fungi propagules using wet sieving method and root colonization using gridline method. AM Fungi spores subsequently identified by the Gedermann and Trappe identification manuals, some soil characteristics were also analyzed.  The results showed that the number of spores at each sampling location ranged from 5.0 to 35 spores/50 gr of soil. The highest number of spores is found in the rhizosphere of Lycopersicum esculentum and the lowest is in Oryza sativa. The percentage of roots infected ranged from 15,3 to 76,38%, the highest of infections found in Oryza sativa and the lowest in Capsicum annuum. There were four AM Fungi morphotypes on agricultural soil of Oransbari i.e Glomus, Acaulospora, Scutellospora and Gigaspora.  Soil pH and water content influenced the presence of AM Fungi, while Nitrogen and Phosphorus content did not influence the spore numbers in the soil as well as in the root.  This might be related to the routine and highly use of inorganic fertilizers and pesticides in these areas.

Abstract

This study aims to improve the development of Dalbergia trichocarpa, a Malagasy native tree species, on a soil invaded by Grevillea banksii, an invasive plant species in eastern part of Madagascar, by inoculating seedlings with mycorrhizal fungal, Rhizophagus irregularis and AMFn strains or rhizobial STM609 and Rn strains, or a mixed rhizobial-mycorrhizal strains. After five months of growth, the results showed that single or dual inoculation boosted significantly the development of D. trichocarpa, compared to control treatments and all parameters measured were markedly different between the time periods of plant invasions. Indeed, the dry mass of aerial biomass was significantly higher in inoculated seedlings than in control seedlings. It was also observed that the number of nodules and the arbuscular mycorrhizal colonization rates of D. trichocarpa increased significantly with inoculated plantlets. However, soil inoculated with the rhizobial strain STM609 alone showed a significantly high global soil microbial activity and the dual inoculation has promoted the soil acid phosphatase activity. These results suggest that dual inoculation with rhizobial and arbuscular mycorrhizal strains was significantly beneficial to the growth, nodulation and mycorrhizal colonization rates of D. trichocarpa in the soil overgrown by G. banksii, an invasive exotic plant species. Thus, this biotechnology can be used for restoration of degraded ecosystems in Madagascar with native tree species.

Abstract

The symbiosis of arbuscular mycorrhizal fungi with plants is the oldest symbiosis in the world. The obligate nature of mycorrhizal fungi in symbiotic relationships is believed to underlie its enduring presence to this day. The application of arbuscular mycorrhizal fungi (AMF) based fertilizers has become increasingly common. Spores are the most important organs that determine the quality of AMF-based fertilizers, along with AMF colonization in the roots. The production of AMF spores is greatly influenced by plant physiology, including photosynthesis processes affected by canopy abundance, as well as the type of planting medium, which determines plant root growth and AMF habitat. This study was conducted to investigate the effect of pruning and planting medium composition on AMF infection and spore production in AMF propagation using sorghum as the host plant. The pruning levels tested were at one, two, and three months after germination, and thereafter, each plant was maintained for 136 days after planting (DAP). The tested planting medium composition was the ratio between zeolite and compost in five different compositions: (v/v) 1) 100:0, 2) 90:10, 3) 70:30, and 4) 50:50. The chemical characteristic of compost used was contained 15.5% C, 1.49% N, 2.54% P2O5, 1.49% K2O, pH 6.6, and some microelements such as Cr, Fe, Zn, and Mn at 5.2 ppm, 5961 ppm, 294 ppm, and 199 ppm, respectively. The Sukabumi‘s zeolite used had a size of 2-3 mm. Propagation of AM fungal spores was carried out using polybags containing 10 kg of medium according to the treatment. Plant maintenance was carried out by alternating between watering with water and Johnson nutrient solution. Watering was performed until the plants were 120 days old, and subsequently, no watering was done until 136 days after planting. The observed parameters were the development of AMF spore numbers until a 4.5-month incubation period. The results showed that pruning time can affect spore production if the plant has reached a certain vegetative age, which is three months for sorghum. Additionally, adding 10% compost to zeolite medium can enhance spore formation, even though sorghum growth may not be at its maximum in this medium composition.

Abstract

Solanum melongena L. is among the most economically valued horticultural crops globally. In the Philippines, the annual production of this staple crop increases continually. However, several biotic and abiotic factors deteriorate its overall growth and productivity. Recently, the use of sustainable biofertilizers such as arbuscular mycorrhizal fungi (AMF) is gaining interest because of their beneficial impacts on overall plant productivity. One way of examining plant productivity is through root structure architecture (RSA) assessment. Hence, this study aimed to investigate the effects of AMF on the RSA of eggplants to supplement valuable data on its beneficial effects as a biofertilizer. Seedlings were inoculated with four treatment conditions AMF + vermicompost (AMF + V), AMF alone (AMF), NPK fertilizer (NPK), and native soil (C) followed by RSA assessment Results showed that treatments AMF + V and AMF alone significantly promoted lateral root branching. Furthermore, the total diameter and surface area showed a significant increase under treatment AMF + V. Overall, the mycorrhizal-root association presented enhancement towards eggplant RSA which strongly establishes the efficacy of AMF as a promising solution in promoting sustainable agriculture.
