Full textAbstract:
Angular leaf spot disease caused by Phaeoisariopsis griseola is the most important disease which caused yield losses up to 80% of common beans. This study aims to induce natural defense of common bean against angular leaf spot disease by mycorrhization. The samples of Phaeoisariopsis griseola were collected in the field of 02 different agro-ecological zones considered as major bean production area in Cameroon. The Phaeoisariopsis griseola were isolated on PDA solid medium, and identified based on morphological. A pot experiment was carried out using a bifactorial device. The first factor was two varieties of common bean (GLP 195-C and PNG). The second factor consisted of eight treatments, namely T0 : absolute control, T1 : mycorrhizal treatment with Acaulospora tuberculata, T2 : mycorrhizal treatment with Gigaspora gigantea, T3 : mycorrhizal treatment with Entrophospora infrequens, T4: Terazeb synthetic fungicide treatment (positive control), T5 : mycorrhizal treatment with Acaulospora tuberculata and Gigaspora gigantea combination, T6 : mycorrhizal treatment with Acaulospora tuberculata and Entrophospora infrequens combination, T7 : mycorrhizal treatment with combination of Gigaspora gigantea and Entrophospora infrequens. Incidence, severity of angular leaf spot disease and biochemical parameters were assessed. The results showed that pots treated with the mycorrhizae Entrophospora infrequens, Gigaspora gigantea, Acaulospora tuberculata and combinations of mycorrhizae Acaulospora tuberculata and Gigaspora gigantea, Acaulospora tuberculata and Entrophospora infrequens, Gigaspora gigantea and Entrophospora infrequens contributed significantly to improved amino acid content from 44% to 70%, proline content from 20% to 33%, total phenol content from 36% to 60%, protein content from 16% to 41%, flavonoid content from 27% to 82%, tannin content from 60% to 298%, polyphenoloxidase content from 15% to 74% and peroxidase content from 31% to 109% compared with the control in the two common bean varieties. Similarly, the mycorrhizae treatments and the mycorrhizae combination significantly reduced the development of angular leaf spot disease by 20 to 80% compared with the control in both common bean varieties. This work shows that Arbuscular Mycorrhizal Fungi made a significant contribution to reducing the development of angular leaf spot disease in the pots while improving common bean grain yield.

Full textAbstract:
Arbuscular Mycorrhizal Fungi (AMF) are known to have potential as biological agents controlling plant pathogens. This study aims to obtain indigenous AMF isolates that can suppress the attack of Sclerotium rolfsii which causes stem rot disease in peanut. The method used is an experimental method with a Completely Randomized Design with 5 treatments, namely A : AMF Glomus sp-3 + S. rolfsii; B: AMF Acaulospora sp + S. rolfsii; C: AMF Gigaspora sp + S. rolfsii; D: Combined AMF Glomus sp-3, Acaulospora sp, and Gigaspora sp + S. rolfsii; E: Without AMF + S. rolfsii (Control). Each treatment was repeated 5 times. The data were analyzed using Analysis of Variance (ANOVA) using the Statistix 8 program and the Least Significance Different (LSD) test at a 5% significance level. The results showed that the isolates of Acaulospora sp and Gigaspora sp were able to increase the resistance of peanut plants to stem rot disease (suppressing the incidence and severity of the disease) reaching 100%.

At high soil concentrations, copper (Cu) is toxic to plant development. Symbiosis carried out between microorganisms and plant species are alternatives to minimize plant toxicity in copper contaminated soil. The present study aimed to select species of arbuscular mycorrhizal fungi for the development of wheat plants in copper contaminated soil. The experimental design was completely randomized in a 4 × 6 factorial arrangement, with four sources of inocula: three species of arbuscular mycorrhizae (Acaulospora colombiana, Gigaspora Margarita and Rhizophagus clarus) and one without inoculum (control), and six doses of copper in the soil (0, 80, 160, 240, 320, and 400 mg kg-1), with seven replications. Plant height, root length, root volume, root dry mass, specific surface area, average root diameter, root, shoot and grain Cu content and mycorrhizal colonization rate were evaluated. Root dry mass and mycorrhizal colonization were negatively affected by high Cu doses in the soil. The mycorrhizal isolates Acaulospora Colombiana and Gigaspora Margarita provide greater wheat height, root length and specific surface area and lower Cu content. Mycorrhizal colonization with the fungi Acaulospora Colombiana, Gigaspora Margarita and Rhizophagus clarus results in lower copper content in wheat shoots and grains.

Using biological agent microorganisms such as Arbuscular Vesicular Mycorrhiza (AVM) is needed to improve post-mining soil fertility. This research aimed to explore and identify morpho species of AVM in the post-nickel mining areas Soil samples were taken from the tree rhizosphere at each representative point. The soil samples have been isolated using Brundrett's method of wet sieving and decanting; AVM spore density is determined for each 20 g soil sample; and spores are grouped based on morphological traits up to the morphogenic stage of the species. The results showed that there are four mycorrhizal species found in the rhizosphere of plants in the nickel post-mining soil of PT Vale Indonesia Tbk., namely Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp. Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp obtained 18, 8, 8, and 7 morpho species, respectively. The highest spore density is 34 spores of Gigaspora sp4 found in the rhizosphere of Casuarina rumphiana, 57 spores of Acaulospora sp1 in the rhizosphere of Macaranga gigantea, two spores of Glomus sp1, sp2, and sp6 each as many as two spores per 20 g of soil in rhizosphere of Enterolobium cyclocarpum, Dillenia serrata, Maesopsis eminii, 11 spores of Scutellospora sp6 in the Shizigium sp rhizosphere. One finding revealed that Gigaspora and Acaulospora predominated in the rhizosphere over other mycorrhizas. The results of this AVM identification will be the basis for the mass propagation of local AVM for broader use in the post-nickel mining land area in Sorowako. Widespread use of AVM is a form of post-nickel mining land management based on local resource potential, particularly the dominant trees rhizosphere and the most commonly found AVM types. This proves that AVM can colonize plant roots in this nickel post-mining soil and potentially be mass-propagated, especially species.

Full textAbstract:
The existence of allegations about the presence of various mycorrhizae in the forest area of Fatusene Village, East Miomaffo District, North Central Timor Regency, is a benchmark for assessing the characterization of mycorrhizae in the area. The purpose of this study was to isolate and identify mycorrhizae in the forest area of Fatusene Village, East Miomaffo District, North Central Timor Regency. Mycorrhizal identification begins with sampling the soil under the tree stands using the quadratic method. Soil samples were taken randomly at three points per observation plot with a depth of 0-30 cm from the base of the tree trunk. Separation of spores from soil samples was carried out using a wet sieve technique. Data analysis was carried out descriptively by identifying morphological characters including the shape and color of the spores. The results of mycorrhizal research found in the research location of the forest area of Fatusene Village are endomycorrhizal types, especially arbuscular vesicles. Characterization of mycorrhizal spores showed that there were three different spore genera in soil samples, namely the genus Glomus, Gigaspora and Acaulospora. The three genus found in the soil samples at the study location were present in each dominant tree with different numbers of individuals. The spores of the three mycorrhizal genus found at the study site were 65 spores, with the distribution of 35 spores genus Glomus, 20 spores genus Acaulospora and 10 spores the genus Gigaspora. The characters the genus glomus are round, slightly round, oval and brown and dark brown in, have hyphae and are equipped with oily fluid spots on cook spores. The characters the genus Acaulospora are round and oval in shape, blackish brown in color, brownish red and brownish yellow, have several layers of cell walls, one of which is dark in color. The characters the genus Gigaspora are irregular in shape, somewhat round and round, yellow, brownish yellow, to yellowish brown, large in size and black spore walls. Conclusion The mycorrhizae found in the study site were endomycorrhizal, especially arbuscular vesicles which consisted of 3 genera, namely Glomus, Acaulospora and Gigaspora. The characters of the genus glomus are round to oval in shape, dark brown in color, have hyphae and spotting of oil. The characters the genus Acaulospora are round and oblong, brownish yellow in color, have several layers of cell walls. The genus Gigaspora is slightly round and round, yellowish brown in color, large and black spore walls.

Abstract The study aims to determine the presence of arbuscular mycorrhiza fungi (AMF) in roots and rhizosphere soils of Cucurbitaceae plants (Luffa cylindrica, Lagenaria siceraria, Benincasa hispida, Cucumis sativus, Momordica charantia) grown at Hoc Mon, Cu Chi, Binh Chanh district, Ho Chi Minh City. Identification of the AMF was made by observation of spore morphology, AMF structures in root tissues and confirmed by sequencing of SSU rDNA. The colonization ratio was 5.1%, and the spore density of AMF in the rhizosphere soil was an average of 63.6 spores/50 g soils and the root symbiotic ratio was 5.1%. The morphological identification of AMF has determined spores of five genera: Glomus, Acaulospora, Gigaspora, Scutellospora and Sclerocystis, demonstrating a morphological variety of AMF spores in rhizosphere soil of Cucurbitaceae plants. Three species were identified based on the sequence analysis of the SSU rDNA gene amplified by the AML1/AML2 primer: Acaulospora cavernata, Acaulospora spinosa, and Rhizophagus intraradices. Cucumis sativus had the highest spore density and root ratio, followed by Lagenaria siceraria and Momordica charantia in the greenhouse trial of AMF re-infection in three plants: Cucumis sativus, Lagenaria siceraria, and Momordica charantia. The AMF identification result revealed five genera: Glomus, Acaulospora, Gigaspora, Scutellospora, and Sclerocystis in the rhizosphere soil, as well as symbiosis in the roots of 3 genera: Glomus, Acaulospora, and Scutellospora.

O amendoim (Arachis hypogaea) é uma planta que durante as fases iniciais do seu desenvolvimento sofre mais intensamente a competição das plantas daninhas, prejudicando sensivelmente sua produção. Uma forma muito eficiente de solucionar esse problema é o uso do herbicida trifluralin; no entanto, seu uso pode prejudicar a micorrização, uma associação benéfica formada por fungos e raízes da planta hospedeira. Este trabalho objetivou avaliar o efeito do herbicida trifluralin e de duas espécies de fungos micorrízicos (Gigaspora margarita e Acaulospora scrubiculata) na micorrização e no crescimento inicial de plantas de amendoim. O trabalho foi realizado na casa de vegetação do Centro de Ciências Agrárias, Ambientais e Biológicas da Universidade Federal do Recôncavo da Bahia, no município de Cruz das Almas - BA. Utilizou-se o cultivar de amendoim Vagem Lisa. Os tratamentos testados envolveram aplicação (C/H) ou não (S/H) de herbicida e inoculação individual de dois fungos micorrízicos: Gigaspora margarita (F1) e Acaulospora scrubiculata (F2), sendo os seguintes: S/H + F1, S/H + F2, C/H + F1, C/H + F2, C/H S/F (sem fungo) e S/H S/F. O delineamento experimental foi inteiramente ao acaso, em esquema fatorial (2 x 2) + 2, com quatro repetições. Os resultados mostraram que a colonização micorrízica para Gigaspora margarita foi de 63% e, quando se aplicou o herbicida, de 44%; Acaulospora scrubiculata apresentou baixo índice de colonização (5,75% e 1%, sem e com herbicida, respectivamente); a eficiência micorrízica foi superior na associação com G. margarita; a dependência micorrízica foi aumentada na presença do herbicida para as duas espécies de fungo inoculadas; a altura da planta, o volume de raízes, a massa seca da parte aérea e das raízes e a massa seca da planta foram superiores aos dos demais tratamentos. Conclui-se que o herbicida trifluralin prejudica a micorrização e o crescimento inicial das plantas de amendoim. A espécie de fungo Gigaspora margarita promove o crescimento inicial das plantas de amendoim, porém a espécie Acaulospora scrubiculata não foi eficiente para promover esse crescimento.

Cassava is widely grown in Inceptisol. As agricultural land, the soil has several problems, i.e., high soil acidity, easily leached soil surface layers, unstable soil aggregates, and slow permeability. Arbuscular mycorrhizal fungi (AMF) form a symbiotic relationship with over 80% of higher plant species. However, the effectiveness of AMF on cassava has not been widely reported. This study aimed to determine the effect of AMF inoculants on the vegetative growth of cassava in Inceptisol. The AMF inoculants used were Gigaspora sp., Glomus manihotis, and a consortium of Acaulospora tuberculata and Glomus rubiforme. The experiment was performed in a Randomized Block Design with 8 treatments and 3 replications, i.e., M1 = G. manihotis; M2 = Gigaspora sp.; M3 = consortium of A. tuberculata-G. rubiforme; M4 consortium of G. manihotis-Gigaspora sp.; M5 consortium of G. manihotis-A. tuberculata-G. rubiforme; M6 consortium of A. tuberculata-G. rubiforme-Gigaspora sp.; and M7 consortium of G. manihotis-A. tuberculata-G. rubiforme-Gigaspora sp.; and control (as recommended dose of NPK fertilizers). In the AMF application treatment, 75% of the recommended NPK fertilizer was applied, thus saving 25% from the control. A total of 50 AMF spores were applied to each cassava plant and maintained for 8 weeks. The data were analyzed using the RStudio 4.1.1 program. The results showed that all treatments with AMF gave various effectiveness and could compete with the indigenous AMF. AMF application significantly increased the vegetative growth of cassava grown in Inceptisols, i.e., shoot and root dry weight, root length, P-uptake, and percentage of root infection. Application of G. manihotis and the consortium of A. tuberculata-G. rubiforme-Gigaspora sp. effectively increased cassava plants' growth for 8 weeks in Inceptisol. The AMF application could save 25% on the use of NPK fertilizers.

This study aimed to assess the impact of different land uses on the spore density and richness of arbuscular mycorrhizal fungi (AMF) in a Red Latosol of a tropical savanna biome in Brazil (“Cerrado”). Ten soil samples and roots were obtained from a riparian forest, a pasture, an annual crop production system with no tillage, and a coffee plantation in dry and wet seasons. Spores were extracted, counted, and identified from field soils, and roots were stained to assess mycorrhizal colonization. A total of 42 AMF species were detected in all four land uses. The genus Acaulospora had the largest number of species (18), followed by Glomus (6) and Gigaspora (5). Gigaspora decipiens and Gigaspora margarita were present in all areas, regardless of the sample period. Gigaspora decipiens was the species most frequently recovered and contributed to the majority of spores in coffee plantations and riparian forest. Cetraspora pellucida was dominant in the area of no tillage and Acaulospora tuberculata in the pasture. Low species richness was detected in soils under the coffee plantation, with AMF communities dominated almost exclusively by members of Gigasporaceae. We conclude that the area under the coffee plantation caused a reduction in the richness of AMF species and promoted a dominance of a single family AMF compared with the pasture area.

Os campos de murundus são fitofisionomias de ocorrência no bioma Cerrado com funções ecológicas importantes para a manutenção da sustentabilidade do solo; e a conversão para sistemas agrícolas pode provocar alterações nos atributos físicos, químicos e biológicos do solo ainda não avaliados, como a redução da biodiversidade de fungos micorrízicos arbusculares. O objetivo deste estudo foi avaliar como a conversão dos campos de murundus em áreas de sistema agrícola altera a comunidade de fungos micorrízicos arbusculares (FMAs). Os tratamentos constituíram-se de três áreas agrícolas submetidas ao mesmo manejo e uso agrícola em uma cronossequência (7, 11 e 14 anos) e duas na área referência [campo de murundus, em topo (TM) e entre os murundus (EM)]. Os esporos de FMAs foram extraídos, contados, e as espécies de FMAs identificadas pelas características morfológicas. O total de FMAs recuperado foi de 27 espécies, sendo nove espécies da família Acaulosporaceae, uma Ambisporaceae, sete Glomeraceae, duas Claroideoglomeraceae e oito Gigasporaceae. Desse total, as espécies Acaulospora scrobiculata, Glomus macrocarpum, e Gigaspora sp. ocorreram em todas as áreas nos dois anos estudados. As espécies Acaulospora mellea, Acaulospora cavernata, Acaulospora colombiana, Glomus diaphanum, Scutellospora reticulata e Scutellospora sp. só foram encontradas nos campos de murundus. A conversão de campos de murundus em área agrícola modificou a ocorrência e composição da comunidade de FMAs; as espécies Acaulospora scrobiculata, Glomus macrocarpum, Claroideoglomus etunicatus e Gigaspora sp ocorreram em todas as áreas e a não ocorrência de algumas espécies nas áreas de cultivo, como as espécies Acaulospora cavernata, Acaulospora colombiana, Rhizophagus diaphanus, Scutellospora reticulata e Scutellospora sp. representa perda de diversidade desses fungos.

Full textAbstract:
Coffea arabica plantations in Central Sulawesi are carried out on the Napu highland, where this area is dominated by ultisol or yellow red podzolic soils, which have problems of high soil acidity and low availability of macro nutrients. This study used a completely randomised design method consisting of four treatments namely; without organic fertilisers (control)/P0, Leucaena leucocephala leaf compost 3 Kg/tree (P1), Samanea saman leaf compost 3 Kg/tree (P2), Tithonia diversifolia leaf compost 3 Kg/tree (P3), Cow and goat manuire 3kg/tree (P4). The results showed that there were 10 species of Arbuscular Mycorrhizal Fungi (AMF) associated with Coffea arabica plants namely Glomus sp1, Glomus sp2, Glomus sp3, Glomus sp4, Acaulospora sp1, Acaulospora sp2, Acaulospora sp3, Gigaspora sp1, Gigaspora sp2 and Gigaspora sp3. Furthermore, the higher density of FMA spores was found in the treatment without organic fertiliser application/control (P0) which was 31 spores/10 g soil, compared to the treatment of Tithonia diversifolia leaf compost treatment (P3) with 11 spores/10 g soil, cow and goat manure treatment (P4) with 3 spores/10 g soil, and Samanea saman leaf compost treatment (P2) with 2 spores/10 g soil. And in the Leucaena leucocephala leaf compost treatment (P1), no AMF spores were found. The difference in AMF spore density in the various organic fertiliser treatments mentioned above is related to the effect of improving soil chemical properties on the soil. The results of this study contribute to the understanding of the importance of soil amendments with organic fertilisers for the improvement of organic and sustainable arabica coffee production in the future.

Para verificar os efeitos da inoculação micorrízica e da adubação fosfatada em mudas de Vochysia maxima (quaruba), foi realizado um experimento em casa de vegetação. Testaram-se nove espécies de fungos micorrízicos arbusculares (FMAs): Gigaspora sp., Acaulospora appendicula, Scutellospora heterogama, Acaulospora sp., Scutellospora sp., Gigaspora margarita, Glomus mosseae, Scutellospora gilmorei e Entrophospora colombiana. A inoculação foi feita pela deposição de solos inóculos de FMAs debaixo da radícula das plântulas, durante a repicagem para copos de plástico de 200 ml, contendo Latossolo Amarelo álico fumigado e não-fumigado. Três meses depois, as mudas foram transferidas para vasos de plástico, contendo 2 kg do mesmo solo, com ou sem a incorporação de fósforo (90 mg/dm³ de solo), na forma de superfosfato simples. O estado nutricional e o crescimento das plantas foram avaliados 12 meses depois da inoculação. As mudas desenvolveram pouco sem aplicação de fósforo, tanto no solo fumigado quanto no solo não-fumigado, mesmo inoculando fungos micorrízicos. Com a aplicação de fósforo, um aumento de 76% em produção de matéria seca foi obtido com a inoculação de Glomus mosseae e Gigaspora sp. no solo fumigado e não-fumigado, respectivamente. Essas duas espécies promoveram também a maior quantidade acumulada de fósforo na parte aérea da planta, sendo 71% pelo Glomus mosseae no solo fumigado e 96% pelo Gigaspora sp. no solo não-fumigado, em relação às mudas não-inoculadas, evidenciando alta exigência de quaruba em fósforo. A inoculação e a adubação fosfatada beneficiaram o crescimento e a absorção de P das plantas, mesmo no solo não-fumigado.

A alta disponibilidade de íons metálicos no solo, dentre eles o Mn2+, pode inibir os fungos micorrízicos arbusculares (FMA), retardando a germinação dos esporos e, conseqüentemente, a formação de micorriza, o que reduz a eficiência simbiótica. O objetivo deste trabalho foi avaliar o efeito do íon Mn2+ sobre a germinação de esporos de seis espécies de FMA dos gêneros Glomus, Acaulospora, Gigaspora e Scutellospora em experimento in vitro Em substrato constituído por areia lavada, adicionaram-se 15; 30 e 75 mg kg-1 de Mn2+, na forma de MnCl2.4H2O, mantendo-se um controle sem adição de Mn. Acondicionaram-se os esporos em envelopes membranosos, introduzindo-os entre duas camadas de areia com diferentes níveis de Mn, em placas de Petri. Após 30 dias de incubação, avaliou-se a germinação dos esporos. Houve decréscimo médio de 32, 49 e 75 % na germinação dos esporos, à medida que se aumentaram as doses de Mn, em comparação ao controle. A germinação de esporos do gênero Glomus foi totalmente inibida na maior dose. O gênero Acaulospora sofreu decréscimos de até 50 % já na dose de 15 mg kg-1 de Mn2+, enquanto os gêneros Scutellospora e Gigaspora apresentaram os maiores índices de germinação de esporos, tendo havido tolerância no caso de Gigaspora, mesmo na maior dose de Mn2+, e estímulo à germinação no caso de Scutellospora até à dose 30 mg kg-1 de Mn2+.

O objetivo deste trabalho foi verificar a influência da inoculação de seis espécies de fungos micorrízicos arbusculares (FMA) (Glomus clarum, Scutellospora heterogama, Glomus etunicatum, Acaulospora scrobiculata, Gigaspora margarita e Glomus manihotis) no desenvolvimento vegetativo, nutrição mineral e conteúdo de substâncias de reserva em porta-enxertos de abacateiro (Persea sp.), oriundos de caroços. Os porta-enxertos foram cultivados em casa de vegetação com cobertura de sombrite (70%) e acondicionados em sacos de polietileno preto (5 L), contendo substrato constituído de solo + areia + resíduo decomposto de casca de acácia-negra (Acacia mearnii) (2:2:1, v:v:v). Dois meses após a infecção das plântulas com FMA (30 g/plântula), observou-se que a dependência do abacateiro aos FMA variou com a espécie de fungo em estudo. Scutellospora heterogama, Acaulospora scrobiculata e Glomus etunicatum proporcionaram melhor nutrição, maior conteúdo em substâncias de reserva e maior desenvolvimento vegetativo das plantas. Glomus clarum somente incrementou a altura das plantas. A infecção com Glomus manihotis não alterou o desenvolvimento vegetativo dos porta-enxertos, e Gigaspora margarita foi prejudicial.

Os fungos micorrízicos arbusculares (FMAs) ocorrem de forma generalizada e formam importante simbiose com a maioria das plantas, mesmo em solos poluídos com metais pesados. Neste estudo, avaliaram-se a ocorrência e a diversidade dos FMAs em quatro locais com gramíneas em uma área de solo contaminado com metais pesados pela extração e industrialização do Zn. Verificou-se a ocorrência generalizada dos FMAs nos locais estudados, sendo esta influenciada pelas concentrações de metais no solo. Encontrou-se um total de 21 espécies, sendo: sete pertencentes ao gênero Acaulospora, seis de Scutellospora, cinco de Glomus, duas de Gigaspora e uma de Entrophospora,Glomus occultum, Acaulospora morrowiae, Acaulospora mellea, Glomus intraradices, Glomus clarum e Scutellospora pellucida foram as de maior ocorrência. A densidade de esporos, a riqueza de espécies e o aumento da dominância relacionaram-se inversamente com as concentrações de metais no solo. Acaulospora mellea, Glomus clarum e Glomus occultum dominaram as populações de esporos no solo. Concluiu-se que os metais pesados exerceram efeito diferenciado sobre os FMAs, dependendo do grau de poluição.

Indigenous arbuscular mycorrhizae Fungi (AMF) have a potential to boost maize (<em>Zea mays</em>) growth and increase the P and Zn uptake through the symbiotic association they form with the plant, even in acidic soils conditions. Five AMF inoculums produced from the most abundant and ubiquitous morphotypes isolated from field soils in maize fields in South Kivu (DRC) were assessed. A greenhouse experiment was conducted to determine the role of these AMF on nutrients uptake in a Nitisol and a Ferralsol. Eight treatments namely inoculums named AMF1 (<em>Gigaspora gigantea</em>), AMF2 (<em>Gigaspora </em>sp<em>.</em>), AMF3 (<em>Gigaspora margarita</em>), AMF4 (<em>Rhizophagus intraradices</em>) AMF5 (<em>Acaulospora reducta</em>), mineral phosphorus fertilizers (Pi), commercial biofertilizer Rhizatech and a Control were laid in a randomized complete block design. In the Ferralsol, Pi application, Rhizatech and AMF2 produced the highest height. Pi application resulted in the best shoot biomass. No difference was observed for the P content, but for the Zn content, AMF2 was the highest. Roots colonization did not vary among treatments. In the Nitisol, AMF4 produced the highest plant height and AMF1 the highiest chlorophyll content. AMF4 and Rhizatech colonized highly the roots. AMF3 gave the highest P however, Zinc content was equal in all treatments and the controls yielded the lowest results. Spores densities in both inoculums produced and experimental soils were low compared to the commercial inoculum but growth and roots colonisation was influenced by fertilization and soils types.

Utilization of arbuscular mycorrhizae fungi (FMA) is an alternative way to improve soil fertility. Therefore, it must be developed by studying deeply the effectivity of the FMA. This is important due to either its ability to associate with almost all of vegetation family in terrestrial ecosystems or its ability to increase plant growth rate, seedlings quality, and crop yield, especially on critical land. A research about effectivity of variously indigenous arbuscular mycorrhizae fungi on P-sorption and Jatropha growth was conducted at laboratorium and glasshouse Agriculture Faculty, Andalas University. This research was aimed to gain the most effective isolate of arbuscular mycorrhizae fungi on growth of and P-sorption by Jatropha (Jatropha curcas L.) plant on critical land. Single isolat such as Glomus sp2, Acaulospora sp1, Gigaspora sp1, and compound isolate M7 (Glomus sp2,+ Acaulospora sp1 + Gigaspora sp1) significantly affected plant height, canopy dry matter, infection percentage and intensity, and P-sorption. M7 Compound isolate was the most effective innoculum. By this isolate, height of Jatropha seedlings was 27.5 cm, canopy dry matter 5.9 g, infection percentage 78.5%, infection intensity was 49.1, and P-sorption by canopy was 1.6 g for each seedling.

Mycorrhiza was considered to enhance plant growth, especially in unfavourable environmental conditions. From 60 samples of rhizospheric soils and roots of black pepper (Piper nigrum) grown in Ba Ria - Vung Tau, Dong Nai, and Gia Lai provinces, the presence of Acaulospora, Gigaspora, Glomite, Glomus,and Scutellospora genera were detected, of which Glomus and Acaulospora were dominants. After 40 days of inoculation, mycorrhiza multiplied 8.5 fold on corn (Zea mays) and 6.5 fold on sorghum (Sorghum bicolor) or goosegrass (Eleusine indica). Black-pepper cuttings on substrate supplemented mycorrhiza showed better growth than the non-inoculated cuttings. Results suggest the potential of applying mycorrhizal fungi as biological agents in sustainable black pepper cultivation, adapting to climate change

This study aimed to explore the characteristics of Arbuscular Mycorrhizal Fungi (AMF) across varying land slope gradients in the conservation area of local pineapple plantations in Majene Regency. The analysis was conducted on five slope categories: flat (0-8%), gentle (8-15%), moderately steep (15-25%), steep (25-45%), and very steep (>45%), to examine the spore density and morphology of AMF as well as to see its relationship to ecological factors such as climate and topography. The results revealed that slope gradients significantly influenced AMF spore density, with the highest density observed on moderately steep and steep slopes. In contrast, lower densities were recorded on flat, gentle, and very steep slopes. Four AMF spore genera were identified: Glomus, Acaulospora, Gigaspora, and Scutellospora. Glomus was dominant across all slopes, Acaulospora was more prevalent on moderate slopes, and Gigaspora preferred steep slopes. Scutellospora was detected in limited quantities on extreme slopes. Environmental factors, including stable temperatures (27.61 °C-27.77 °C), high relative humidity (79.44%-80.41%), and varying precipitation levels, influenced AMF spore distribution and morphology. These findings emphasize the critical role of topography and climate in supporting AMF sustainability in management strategies to conserve AMF biodiversity and enhance crop productivity.

A sand dune area in Santa Catarina, Brazil, was surveyed every 3 months to determine species composition and seasonal variation of arbuscular mycorrhizal fungi populations associated with Spartina ciliata. Spores from 12 fungal species were recovered. Overall species richness was 5.9. A plot of rank versus abundance provided an indirect measure of the structure of the fungal community and showed a linear relationship among species. A mean of 298 spores/100 g soil were extracted from sand dune samples, with Acaulospora scrobiculata forming 50.9% of the total population. The most frequently recovered species at all sampling dates were Gigaspora albida, Scutellospora weresubiae, A. scrobiculata, and one undescribed Scutellospora species. Spore abundance ranged from 0 to 69 spores/100 g soil for all species except A. scrobiculata (60–247 spores/100 g). Spore abundance of each species did not vary significantly through the season. However, several general trends were observed. The number of spores of Glomus constrictum, Glomus etunicatum, and Acaulospora sp. (No. 2) was maximal in winter, whereas that of Gigaspora albida peaked in spring. Species composition and richness of arbuscular fungi in Brazilian dunes appear to be similar to those in sand dunes along the Atlantic coast of the United States. Key words: arbuscular mycorrhizal fungi, ecology, sand dunes, spore populations, Brazil.

Abstract The study aimed to assess the symbiosis between maize (Zea mays L.) and sorghum (Sorghum bicolor L. Moench) with four AMF (Arbuscular Mycorrhizal Fungi) genera: Glomus, Acaulospora, Gigaspora, and Scutellospora. Based on their morphological characteristics, these genera were identified after being isolated from 40 rhizosphere soil samples collected in a vegetable-growing region of Ho Chi Minh City, Vietnam. The trial results demonstrated that growth parameters, including root number, root length, root biomass, and plant height of maize and sorghum plants, all increased significantly in the presence of AMF strains compared to plants without AMF supplementation. After 45 days of inoculation, the genus Glomus exhibited a 62.7% symbiosis rate with the host plant, with an average total spore count of 153.2 spores per 100 g of soil. Acaulospora had an average symbiosis rate of 50.7%, with 138 spores per 100 g of soil. Gigaspora and Scutellospora had lower symbiosis rates (45.8% and 46.7%, respectively), with average spore counts of 123.2 and 106.2 spores per 100 g of soil. Maize had an average spore density of 116.0 spores per 100 g of soil after 45 days of AMF inoculation, making it a more suitable host plant than sorghum for promoting an increase in AM fungal spore production.

Full textAbstract:
Soil and root samples collected from fields cropped to spring wheat (Triticum aestivum L. cv. Katepwa) and lentil (Lens esculenta L. cv. Eston) at 11 sites across four soil zones of Saskatchewan were analyzed for spore numbers, level of vesicular–arbuscular mycorrhizal (VAM) colonization, and VAM species. The number of VAM spores detected in field soils ranged from 78 to 272 per 100 g soil. Vesicular–arbuscular mycorrhizae colonized wheat and lentil at all the field study sites, but levels of colonization in the two crops varied from site to site and the differences were more pronounced in wheat than in lentil. Generally, lentil both exhibited a higher percentage of VAM colonized roots and contained more arbuscules and vesicles than wheat roots. However, wheat appeared to be colonized by different types of VAM depending on the field sites. Differences in VAM colonization were not related to the moisture and temperature gradient of the four soil zones or soil properties. Seven VAM species were isolated by enriching indigenous VAM mixtures (collected from wheat field soils of six field sites) on maize. The VAM isolated most closely resembled Acaulospora denticulata, Gigaspora decipiens, Glomus clarum, Glomus etunicatum, Glomus fasciculatum, Glomus mosseae, and Glomus versiforme. The species composition of the VAM community varied at the different field sites.Key words: VAM, Acaulospora, Gigaspora, Glomus.

This study investigated the impact of seasonal variation on the richness and composition of Arbuscular mycorrhiza fungi (AMF) communities in soil from rainforest vegetation in Rivers State, Nigeria. Samples of top soil (0-15cm) and subsoil (15-30cm) were collected from rainforest vegetation in Port-Harcourt, and sampling months were categorized into rainy season, peak of rainy season, dry season and peak of dry season based on the data obtained from NiMET during the study period. A potted experiment was carried out at the teaching and research farm of the Rivers State University from January to April (dry season) and April to July (rainy season) to determine the colonization status of AMF in rhizosphere soils planted with cowpea. Morphology and microscopy were used for AMF identification. A total of eight genera of AMF namely: Glomus, Acaulospora, Gigaspora, Paraglomus, Rhizophagus, Dentiscutata, Archeaospora, and Clariodeglomus were isolated and identified in rhizosphere soils of cowpea cultivated, and the mycorrhiza genera followed the order: Acaulospora > Glomus > Archeaspora > Clariodeoglomus > Rhizophagus > Paraglomus > Dentiscutata > Gigaspora. AMF colonization and population was higher in the dry season than in the rainy season indicating that seasonal variations has an impact on AMF diversity, population, and colonization of cowpea rhizosphere. Seasons can be taken advantage of to improve plant productivity and health.

Fungos micorrízicos arbusculares (FMAs), estabelecendo simbioses eficientes com plantas, desempenham papel importante na sustentabilidade dos ecossistemas e podem ser manejados para a revegetação bem sucedida de áreas degradadas. A eficiência da simbiose está relacionada não só aos genótipos dos simbiontes, i.e, FMA e espécie vegetal, como também às condições ambientais que influenciam a expressão da relação simbiótica. Assim, o primeiro passo visando ao manejo de simbioses eficientes é estudar a variabilidade de FMAs quanto à eficiência com diferentes espécies vegetais. Neste estudo, avaliaram-se a colonização micorrízica e a eficiência simbiótica de isolados de FMAs obtidos de áreas de mineração de bauxita em reabilitação em dois ambientes (campo e serra), no crescimento de mudas de duas espécies pioneiras [aroeira (Schinus terebenthifolius) e trema (Trema micrantha)] e de duas espécies secundárias iniciais [açoita-cavalo (Luehea grandiflora) e sesbânia (Sesbania virgata)], em solo de baixa fertilidade. O experimento foi realizado em casa de vegetação, por 120 dias. Para cada espécie vegetal, foram aplicados 10 tratamentos de inoculação com FMAs (isolados de FMAs ou de sua mistura): Acaulospora longula, Paraglomus occultum, Glomus sp., Gigaspora sp., Acaulospora spinosa e a mistura destes, todos oriundos de área de campo; e Acaulospora scrobiculata, Paraglomus occultum, Glomus sp. e a mistura destes, todos oriundos de área de serra. Para comparação, foram acrescentados ainda um tratamento-referência inoculado com Glomus etunicatum eficiente e um tratamento não-inoculado como controle. Plantas de todas as espécies apresentaram crescimento reduzido na ausência de FMAs (controle), porém beneficiaram-se de modo diferenciado dos tratamentos de inoculação. Todos os isolados, ou sua mistura, foram eficientes em promover o crescimento de sesbânia, enquanto para trema e aroeira somente um isolado de Glomus sp. não foi eficiente. Para o açoita-cavalo, os dois isolados de Glomus sp. estudados foram ineficientes. Nenhum dos FMAs isolados da área de mineração de bauxita promoveu crescimento superior ao obtido com o tratamento-referência com G. etunicatum. No entanto, os isolados do campo Gigaspora sp., Paraglomus occultum e Acaulospora spinosa foram tão eficientes quanto G. etunicatum em promover crescimento das quatro espécies vegetais. Os resultados indicam que mesmo áreas tão degradadas como aquelas submetidas à mineração de bauxita podem conter populações de FMA eficientes, que podem contribuir para reabilitação da área.

O cedro-australiano (Toona ciliata M. Roem var. australis) é uma espécie que tem apresentado potencial de utilização florestal no Brasil. Deste modo, o objetivo deste trabalho foi determinar a resposta de mudas de cedro-australiano à inoculação com fungos micorrízicos arbusculares (FMA) em diferentes doses de fósforo (P). O experimento foi conduzido em delineamento inteiramente casualizado em esquema fatorial 8 x 2, com cinco repetições. Os tratamentos consistiram na inoculação de sete espécies de FMA: Rhizophagus clarus, Claroideoglomus etunicatum, Racocetra gregaria, Acaulospora colombiana, Acaulospora morrowiae, Gigaspora margarita e Dentiscutata heterogama, além de um tratamento sem inoculação; sendo submetidos a duas doses de fosfato, 25 e 250 mg dm-3 que equivaleram a teores de 10,7 e 41,3 mg dm-3 P no solo, respectivamente. Avaliou-se a porcentagem de colonização micorrízica, esporulação, altura, diâmetro, matéria seca da parte aérea e acúmulo de nutrientes, 150 dias após o transplantio. Houve diferença em função das doses de P e dos isolados nas variáveis avaliadas. Os isolados Claroideoglomus etunicatum e Acaulospora colombiana beneficiaram o crescimento e a absorção de nutrientes do cedro-australiano em baixa disponibilidade de P, enquanto que Acaulospora morrowiae se mostrou mais promissor em solos com maior disponibilidade desse nutriente. Esses isolados proporcionam elevada colonização micorrízica no cedro, favorecendo a produção de mudas de qualidade com vistas ao estabelecimento e produtividade de plantios comerciais.

Full textAbstract:
Currently, southern Minas Gerais (MG) state is an important producer of different olive tree (Olea europaea L.) cultivars because, in this region, the plants can differentiate the buds to produce flowers and fruit. To stimulate the rooting of cuttings, the synthetic hormone indole-3-butyric acid (IBA) at a concentration of 3 g L−1 is used commercially. However, few studies have investigated arbuscular mycorrhizal fungi (AMF), isolated or combined with rhizobacteria, as a biotechnological tool to produce hormones that function in the rooting of olive tree cuttings. The aim of this study was to evaluate the capacity of different AMF species (Rhizophagus clarus, Gigaspora rosea, or Acaulospora scrobiculata), combined or not with IBA or rhizobacteria, to promote the rooting of three olive tree cuttings (Arbequina, Grappolo 541, and Maria da Fé) with potential for cultivation in this region. For this, three experiments were conducted at the Experimental Farm of EPAMIG in Maria da Fé (MG), and the rooting potential of the olive tree cuttings inoculated with I) AMF, II) AMF combined with increasing doses of IBA, and III) AMF combined with three isolates of rhizobacteria was evaluated. The inoculation of olive tree cuttings of cultivars Arbequina, Grappolo 541, and Maria da Fé with Rhizophagus clarus, Gigaspora rosea, or Acaulospora scrobiculata combined or not with IBA or rhizobacteria did not significantly promote rooting. Alternative forms of rooting olive tree cuttings are still a challenge, and further studies for standardizing methodologies and experimental conditions are required.

Arbuscular mycorrhizal fungi (AMF) are potential biofertilizers for plants. The succeed and quality of AMF inoculation is related to the type of AMF and plants. This study aimed to find the most effective AMF species in Indigofera zollingeriana nurseries. This experiment study was designed using a completely randomized design with six treatments and five replications based on different types of AMF in single and consortium forms. Treatment details include: IFMIX (consortium: a mixture of five types of AMF), IFTE (Glomus etinucatum), IFTM (Glomus manihotis), IFTA (Acaulospora tuberculata), IFTG (Gigaspora margarita), IFTS Glomus sp. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's Multiple Range Test. Based on the results of variance, AMF inoculation at Indigofera zollingeriana nurseries in a single form (IFTE, IFTM, IFTA, IFTG, and IFTS) resulted in effectiveness that was not significantly different with the consortium FMA inoculation (IFMIX) against AMF colonization, plant height, stem diameter, fresh and dry biomass of plants. Inoculation of inoculums in a single IFTE form resulted in a higher colonization value (p<0.05) than single inoculums IFTA and IFTM. It can be concluded that inoculation of a single AMF (Glomus etinucatum, Glomus manihotis, Acaulospora tuberculata, Gigaspora margarita, Glomus sp.) against AMF consortium produced the same symbiotic effectiveness on root colonization, morphological response and plant biomass production level in Indigofera zollingeriana nurseries. The root colonization rate of a single IFTE inoculum was better than a single inoculum of IFTA and IFTM.

Full textAbstract:
Copper is a micronutrient essential for plant growth since it is part of the constitution of enzymes and proteins. However, it can become toxic to plants when in high concentrations in the soil. The association between microorganisms and plants is an alternative for reducing the negative effects of excess copper on plants. The objective of this work was to determine the influence of inoculation and co-inoculation of arbuscular mycorrhizal fungi and Azospirillum brasilense in a wheat crop grown on soil contaminated with copper. The experimental design used was entirely randomized in a bifactorial arrangement of 5 x 2, with five sources of inocula, (Azospirillum brasilense; Acaulospora colombiana; Gigaspora margarita; Acaulospora colombiana + Azospirillum brasilense; Gigaspora margarita + Azospirillum brasilense;), two doses of copper (0 = natural soil content and 400 mg kg-1), and eight replicates. We evaluated the height of plants, number of tillers, root length, root volume, dry root mass, specific surface area, average root diameter, copper content in the root, straw and grain, productivity, and percentage of mycorrhizal colonization. The inoculation with A. brasilense increases the number of tillers, plant height, and productivity compared to mycorrhizal fungi. The co-inoculation of these microorganisms does not contribute positively to these evaluated parameters, regardless of the dose of Cu applied to the soil. Co-inoculation of A. brasilense with mycorrhizal fungi does not reduce copper in the aerial part of wheat plants, regardless of the evaluated species, even in soil contaminated with copper.

Full textAbstract:
This paper focuses on Eremanthus incanus Less. (Asteraceae), a common species of highland regions in Brazil. The effect of arbuscular mycorrhizal (AM) inoculation on plant growth (height and diameter) was evaluated. Roots were examined from individuals randomly selected from undisturbed areas of highland vegetation and from an experimental restored site. Results showed that E. incanus presented high AM colonization both in restored and undisturbed sites. Moreover, AM colonization was significantly higher in the inoculated treatment than in the non-inoculated one. The species presented Arum-type colonization and frequent production of vesicles, especially in the restored site. Arbuscular mycorrhizal inoculation stimulated plant growth (height and diameter). Ten AM fungi (AMF) taxa were found in the studied rooting zones: Acaulospora spinosa, A. elegans, A. foveata, Acaulospora sp., Gigaspora margarita, Glomus sp., Dentiscutata biornata, D. cerradensis, Dentiscutata sp. and Racocetra verrucosa. These results revealed that AMF is a common and important component in highland vegetation in Brazil, and should be included in future restoration programs.

Population of arbuscular mycorrhizal fungi (AMF) in soil in terms of spore was assessed for two land use patterns, a 5-year fallow (5YrF) of shifting cultivation and a homestead (HTD) area of Karbi-Anglong District, Assam. The infective AMF propagules were also determined by Most Probable Number (MPN) pot culture technique growing Maize and compared with a Natural Forest (NF) of about 250 years old. Spore number was lowest in HTD soil with three species of Glomus, 5YrF soil found to contain 6 species belonging to the genera Acaulospora, Gigaspora and Glomus and the NF soil contained 4 species of genera Glomus and Gigaspora. Infective AMF propagules as found in the pot experiment were lowest at HTD site soil, whereas the same were highest in NF soil. Significantly higher shoot biomass was observed at 10-4 dilution of AMF inoculum collected from all the sites. Reduction in root length colonization in Maize was observed at higher dilutions in the pot with inoculum from HTD site.

Foram realizados três experimentos, em casa de vegetação. No primeiro, empregou-se como substrato uma mistura de 2:1:1 de areia, solo (Latossolo Vermelho Eutroférrico) e esterco de curral; no segundo, uma mistura de 1:1 de solo e areia e no terceiro, uma mistura de 9:1 de solo e esterco de curral. Os FMAs empregados foram: Acaulospora sp.(IAC-13), Gigaspora margarita, Glomus sp (IAC-27), Acaulospora morrowae, Acaulospora sp. (IAC-44), Acaulospora scrobiculata, Scutellospora heterogama, Glomus clarum,Glomus sp. (IAC-28), Entrophospora colombiana, Glomus etunicatum e Glomus macrocarpum. No terceiro experimento, empregaram-se G. clarum, Glomus sp. (IAC-28), G. margarita, G. etunicatum e G. macrocarpum (IAC-50), uma mistura dessas espécies e populações de fungos nativos, oriundas de solo de uma cultura de maracujá estabelecida no campo e multiplicadas em Brachiaria decumbens, maracujazeiro e amendoinzeiro. Os efeitos positivos da micorrização foram maiores no substrato sem adição de matéria orgânica (esterco de curral), não superando, entretanto, o efeito da sua adição. G. clarum, G. etunicatum e G. margarita promoveram aumento significativo na produção de matéria seca. No substrato com adição de 25% de matéria orgânica, os fungos Acaulospora sp. (IAC- 44) e A. morrowae foram eficientes na promoção do desenvolvimento das mudas, com desempenho comparável ao Glomus sp. (IAC- 28) no substrato com adição de 10% de esterco de curral. G. clarum mostrou efeito parasítico, diminuindo o crescimento das plantas no substrato com 25% de matéria orgânica.

The exploration of arbuscular mycorrhiza fungi from sugarcane plantation in marginal land in South Sulawesi was carried out to find the source of inoculums showing effective infection. Soil samples were taken from four area with different characteristic of marginal land, namely land with low organic matter content, clay texture, limited irrigation, and undulating land. Mycorrhizae contained in the soil samples were then observed, and the spores obtained were used as the source of isolation by a single spore culture. The mycorrhizal spores were isolated by wet sieving and centrifugation method with 48% sucrose, which were observed under a compound microscope for spore details (100-1000x). Sugarcane root samples were taken to observe mycorrhizal infection in sugarcane root tissue by root staining method. The results of the study showed that the greatest diversity of mycorrhizal genera was found in soil samples of Jambua Block (Glomus, Gigaspora, and Sclerocistis) and AJ-5 Block area (Glomus, Acaulospora, and Sclerocistis). Single-spore isolates obtained were Glomus sp. and Acaulospora sp. Infection test result on four sugarcane varieties commonly grown in Takalar Sugar Factory showed that infectivity of mycorrhizal isolate of Acaulospora sp. was the highest (75%) and significantly different (LSD’test, p 0,05) compared to that of Glomus sp. (66%).
