ABSTRACT The production of inoculum from arbuscular mycorrhizal fungi (AMF) at a large scale and low cost is essential for establishing methods to assist in producing pineapple plantlets with high nutritional and phytosanitary quality. However, this objective is difficult to accomplish because of the biotrophic nature of these fungi. The on-farm multiplication method for AMF inoculum presents a good alternative to supply the demand for the production of glomerospores. This study aimed to multiply and evaluate AMF inoculum originating from […]

Efficiency of the On-Farm Mycorrhizal Inoculant and Phonolite Rock on Growth and Nutrition of Schinus terebinthifolius and Eucalyptus saligna

Chaiane Schoen, Juarês José Aumond, Sidney Luiz Stürmer


ABSTRACT: The production of tree seedlings with high survival rate and growth is influenced by the substrate, which may be composed of biological and non-biological materials that help plant growth. The objective of this study was to evaluate the efficiency of a mycorrhizal inoculant on farm and the use of a potassic rock (phonolite) on growth and nutrition of Eucalyptus saligna Sm. and Schinus terebinthifolius Raddi under greenhouse conditions. Both species were assigned to three mycorrhizal treatments [no inoculated control […]

Occurrence and Structure of Arbuscular Mycorrhizal Fungal Communities in Cassava after Cultivation of Cover Crops as Observed by the “PCR-DGGE” Technique

Elaine dos Santos Heberle, Rafael Dutra de Armas, Daniel Alexandre Heberle, Sidney Luiz Stürmer, Luiz Augusto Martins Peruch, Paulo Emílio Lovato, [...]


ABSTRACT Cassava (Manihot esculenta Crantz) is a highly mycotrophic crop, and prior soil cover may affect the density of arbuscular mycorrhizal fungi (AMFs), as well as the composition of the AMFs community in the soil. The aim of this study was to evaluate the occurrence and the structure of AMFs communities in cassava grown after different cover crops, and the effect of the cover crop on mineral nutrition and cassava yield under an organic farming system. The occurrence and structure […]

Arbuscular mycorrhizal fungi (AMF) play an important role in natural ecosystems as they influence plant nutrition and soil structure. The aim of this study was to determine the mycorrhizal inoculum potential and the relationship between mycorrhizal mycelium length of AMF and aggregation of riparian soils. Soil samples were collected in riparian areas in the Itajai Açu river watershed, between the municipalities of Gaspar and Navegantes, Santa Catarina, Brazil. Eight areas were sampled within three soil classes: Cambissolo (Inceptisol) (C), Gleissolo […]

On-farm production of mycorrhizal inoculum using residues from the forestry industry

Marlon João Czerniak, Sidney Luiz Stürmer


Production of arbuscular mycorrhizal fungi (AMF) inoculum using the on-farm method is an alternative to stimulate the use of microbial inoculant in plant production systems and to reduce the cost associated with purchase of this product. The goal of this study was to evaluate the potential of residues from the forestry industry, pine bark (CP) and pulp sludge (LC), as components of the substrate used to produce on-farm mycorrhizal inoculum. Sorghum plants pre-colonized with the AMFs Claroideoglomus etunicatum RJN101A and […]

Arbuscular mycorrhizal fungi in “murundu fields” after conversion to farm systems in the cerrado

Paula Camylla Ramos Assis, Orivaldo José Saggin Júnior, Helder Barbosa Paulino, Sidney Luiz Stürmer, José Oswaldo Siqueira, Marco Aurélio Carbone Carneiro


The murundu fields (Campos de Murundus) are characterized by mounds occurring in some parts of the Cerrado (Brazilian tropical savanna) biome with important ecological functions for the maintenance of soil sustainability. Conversion to agricultural systems may lead to changes in physical, chemical, and biological soil properties not yet assessed, such as reduction in the biodiversity of arbuscular mycorrhizal fungi. The aim of this study was to evaluate how the conversion of mound fields into agricultural areas changes the community of […]

Arbuscular mycorrhizal fungi in vegetation types in the Pantanal of Nhecolândia, Mato Grosso do Sul, Brazil

Plínio Henrique Oliveira Gomide, Marx Leandro Naves Silva, Cláudio Roberto Fonsêca Sousa Soares, Evaldo Luis Cardoso, Fernanda de Carvalho, Patrícia Lopes Leal, [...]


The Pantanal (tropical wetland) biome is recognized as one of the largest continuous areas of natural wetlands, harboring a flora and fauna of rare beauty and abundance. Studies to assess the diversity of arbuscular mycorrhizal fungi (AMF) are nonexistent for this environment. The goal of this study was to evaluate the occurrence of AMF in different vegetation types of the Pantanal of Nhecolândia, Brazil. Soil samples were collected during the dry and wet season in a Neossolo Quartzarênico (Entisol) in […]

Arbuscular mycorrhizal inoculation increases biomass of Euterpe edulis and Archontophoenix alexandrae after two years under field conditions

Andressa Franzoi Sgrott, Maristela R. Booz, Rosete Pescador, Teresinha Catarina Heck, Sidney Luiz Stürmer


Inoculation with arbuscular mycorrhizal fungi (AMF) of tree seedlings in the nursery is a biotechnological strategy to improve growth, survival after transplanting, biomass production and to reduce the use of fertilizers. Archontophoenix alexandrae and Euterpe edulis are palm species used in southern Brazil to produce the palm heart, the latter being included in the list of threatened species due to the overexploitation of its native population. The purpose of this paper was to evaluate the effect of mycorrhizal inoculation on […]

Arbuscular mycorrhizal fungi in riparian forest restoration and soil carbon fixation

Felipe Luiz Braghirolli, Andressa Franzoi Sgrott, Rosete Pescador, Alexandre Uhlmann, Sidney Luiz Stürmer


The arbuscular mycorrhizal association established between arbuscular mycorrhizal fungi (AMF-phylum Glomeromycota) and plant roots plays an essential role in plant survival and nutrition. In this review, the idea is outlined that the triad “riparian forest-carbon sequestration-arbuscular mycorrhizal fungi” should be taken into consideration as an environmentally compatible strategy for the recovery of areas formerly covered by riparian forests. We briefly discuss the soil classes found in riparian areas and the C input in terrestrial ecosystems. AMF play an important role […]

Effects of arbuscular mycorrhizal fungi and phosphorus fertilization on post vitro growth of micropropagated Zingiber officinale roscoe

Rosilda dos Santos, Carla Giovana Girardi, Rosete Pescador, Sidney Luiz Stürmer


The rhizomes of Zingiber officinale Roscoe (ginger) are widely used for their medicinal and flavoring properties, whereas the influence of root symbionts on their growth is poorly understood. In this study, the effects of phosphate fertilization and inoculation with a mixture of arbuscular mycorrhizal fungi (AMF) (isolates Glomus clarum RGS101A, Entrophospora colombiana SCT115A and Acaulospora koskei SPL102A) on survival, growth and development of micropropagated ginger were investigated. After transplanting to post vitro conditions, the ginger microplants were subjected to the […]
