Addition of residues and reintroduction of microorganisms in Jatropha curcas cultivated in degraded soil AGRIAMBI
Santos,Adriana A.; Agustini,José A.; Maltoni,Katia L.; Cassiolato,Ana M. R..
ABSTRACT The aim of this study was to evaluate, through mycorrhization (root colonization and number of spores of arbuscular mycorrhizal fungi - AMF), leaf acid phosphatase and soil chemical characteristics, the effects of the addition of residues (macrophytes and ash), hydrogel and the reintroduction of microorganisms in a degraded area cultivated with jatropha. Degradation occurred when the surface soil was removed during the construction of a hydroelectric power plant. The experiment was set in a randomized block design, using a 2 x 2 x 4 factorial scheme, i.e., two inoculation treatments (with and without soil-inoculum), two hydrogel treatments (with and without) and four with the addition of residues (macrophytes - MAC, ash, MAC + ash and control,...

Arbuscular mycorrhizal fungal communities in soils under three phytophysiognomies of the Brazilian Atlantic Forest Acta Botanica
Duarte,Lorrane Marques; Bertini,Simone Cristina Braga; Stürmer,Sidney Luiz; Lambais,Marcio Rodrigues; Azevedo,Lucas Carvalho Basilio.
ABSTRACT Arbuscular mycorrhizal fungi (AMF) play an important role in plant community productivity and structure, and so studying the factors that affect the diversity and structure of this fungal community is important for understanding their ecology in tropical forests. We investigated AMF spore communities and root colonization under three forest phytophysiognomies (Restinga Forest, REF; Lowland Ombrophilous Dense Forest, LLF; and Montane Ombrophilous Dense Forest, MTF). Spore abundance was lowest in LLF and highest in REF, with no statistical differences relative to MTF. Spore diversity indices and root colonization rates were not statistically different among the phytophysiognomies. However, principal components analysis revealed that AMF community...

Arbuscular mycorrhizal fungi in saline soils: vertical distribution at different soil depth BJM
Becerra,Alejandra; Bartoloni,Norberto; Cofré,Noelia; Soteras,Florencia; Cabello,Marta.
Arbuscular mycorrhizal fungi (AMF) colonize land plants in every ecosystem, even extreme conditions such as saline soils. In the present work we report for the first time the mycorrhizal status and the vertical fungal distribution of AMF spores present in the rhizospheric soil samples of four species of Chenopodiaceae (Allenrolfea patagonica, Atriplex argentina, Heterostachys ritteriana and Suaeda divaricata) at five different depths in two saline of central Argentina. Roots showed medium, low or no colonization (0-50%). Nineteen morphologically distinctive AMF species were recovered. The number of AMF spores ranged between 3 and 1162 per 100 g dry soil, and AMF spore number decreased as depth increased at both sites. The highest spore number was recorded...

Cloning of putative ureG genes from Glomus intraradices and urease activities in tobacco arbuscular mycorrhizal roots Scientia Agricola
Takahashi,Daniele; Ditt,Renata Fava; Lambais,Marcio R..
Even though the major benefit of arbuscular mycorrhizae is the increased uptake of phosphate from the soil solution and translocation to the plant, changes in the activity of enzymes involved in nitrogen (N) metabolism have been detected in mycorrhizal roots. Using differential display of reverse-transcripts of tobacco roots not-inoculated or inoculated with Glomus intraradices (Gi), we have cloned two partial cDNAs (NtGi2 and NtGi3). The presence of a conserved CobW/HypB/UreG domain and phylogenetic analyses suggest that NtGi2 and NtGi3 encode isoforms of urease accessory protein G (ureG) highly similar to ureG from fungi. The steady state levels of the putative ureG transcripts were shown to be higher in roots colonized by Gi, as compared to...

Dependência micorrízica de diferentes culturas anuais, adubos verdes e pastagens em solos de cerrado. Infoteca-e
MIRANDA, J. C. C. de; MIRANDA, L. N. de.
ABSTRACT: The arbuscular mycorrhizal fungi in the soil may establish an association with plant roots (mycorrhiza) which benefits the nutrient absorption by the plants and increase the effects of the applied inputs on plant growth. Then, to make profit of this association, it is recommended to increase and diversity fungi in the soil, mainly in those where its population is generally low, as in the cerrado soil. The crop rotation is an agronomic practice that improves the propagation of the arbuscular mycorrhizal fungi in the soil and stimulates mycorrhiza establishment and its effects in plant growth. An adequate rotational sequence to improve formation impplies in the use of mycorrhizal dependent cultures. A table, indicating the percentage of mycorrhizal...

Effects of Arbuscular Mycorrhiza on Osmotic Adjustment and Photosynthetic Physiology of Maize Seedlings in Black Soils Region of Northeast China BABT
Xu,Hongwen; Lu,Yan; Zhu,Xiancan.
ABSTRACT To investigate the effect of arbuscular mycorrhiza fungi on maize growth, osmoregulation substances and photosynthetic physiology, a popular maize variety ZD 958 was measured under potted condition. Arbuscular mycorrhiza (AM) symbiosis promoted plant growth, and enhanced plant height, leaf length, mean leaf width and dry weight. Higher soluble sugar and protein, but lower proline concentrations were detected in AM seedlings than corresponding non-AM seedlings. Quantum yield of PSII photochemistry and potential photochemical efficiency increased by arbuscular mycorrhiza fungi, meanwhile, AM plants had lower primary fluorescence but higher maximal fluorescence and variable fluorescence than non-AM plants. AM enhanced apparent quantum efficiency,...

Factors affecting "in vitro" plant development and root colonization of sweet potato by Glomus etunicatum Becker & Gerd BJM
Bressan,Wellington.
Nutrients media (Murashige & Skoog, Hoagland & Arnon and White's media) supplemented or not with sucrose and substrates (vermiculite, agar and natrosol) were tested for their effects on plant development and root colonization of micropropagated sweet potato, cv. White Star, by Glomus etunicatum Becker & Gerdemann (isolate INVAM FL S329). Addition of sucrose (3%) did not affect plant development. However, hyphal growth and root colonization were depressed. Contrasting responses to media nutrient concentration were observed for plant height, root colonization, and hyphal growth. The highest concentration of nutrients in Murashige & Skoog medium improved plant development, but this medium decreased hypha growth and inhibited...

Ban,Dean; Goreta Ban,Smiljana; Oplanic,Milan; Horvat,Josipa; Novak,Bruno; Zanic,Katja; Znidarcic,Dragan.
Worldwide, a significant increase in watermelon (Citrullus lanatus [Thunb.] Matsum. & Nakai) growing areas has been registered in the last few years. In-row plant spacing has a significant effect on the growth and yield of watermelon, and can enhance competition for water and nutrients. The aim of this study was to investigate the effects of in-row plant spacing (1.0, 1.5, 2.0 and 2.5 m) and arbuscular mycorrhiza (AM) fungi Glomus mosseae inoculations on watermelon growth and yield under field conditions during 2003, 2004, and 2005 year. In 2003, the main vine length, number of leaves, and number of lateral branches were increased quadratically as the in-row plant spacing increased from 1.0 to 2.5. With an increase in the in-row plant spacing the...

Impacto do sistema de plantio direto na diversidade de espécies de fungos micorrízicos arbusculares nativos em solo de cerrado. Infoteca-e
MIRANDA, J. C. C. de; MIRANDA, L. N. de.
ABSTRACT: The no-till and conventional cropping systems, which involve low and high soil disturbance, could affect the number and nature of native arbuscular mycorrhizal fungi species in the soil. These, on the other hand, determine the contribution of arbuscular mycorrhiza on crop responses to used inputs and on the efficiency of the planting system itself, as they have different efficiency levels towards the same host plant. Though, the same total number of species and the same species themselves of arbuscular mycorrhizal fungi, were observed in the no-till and conventional cropping systems. Nevertheless, the no-till system practice is recommended, as the mycorrhizal external mycelium, developed during the former cropping, is preserved and stimulates the...

Inoculation with mycorrhizal fungi on the growth and tolerance to water deficit of coffee plants AGRIAMBI
Moreira,Samuel D.; França,André C.; Rocha,Wellington W.; Tibães,Evandro S. R.; Neiva Júnior,Eudes.
ABSTRACT Water stress can be alleviated in plants inoculated with arbuscular mycorrhizal fungi compared to that experienced by those without mycorrhizae. The objective of this study was to evaluate the growth of coffee plants colonized by arbuscular mycorrhizal fungi under different soil moisture conditions. Seeds of the coffee cultivar Catuaí Vermelho IAC 99 and three fungal inoculants (Rhizophagus clarus, Claroideoglomus etunicatum and Dentiscutata heterogama) were used in this study. The soil moisture contents tested were 40, 60, 80, and 100% of field capacity. Seedlings in the matchstick stage were inoculated with mycorrhizae, and then later planted in plastic pots when they developed four to five pairs of definitive leaves. Both the extent of...

O objetivo deste trabalho foi avaliar o efeito da interação entre fungos micorrízicos arbusculares e a comunidade microbiana do solo, sobre a disponibilidade, a absorção e a atenuação da toxidez de Mn em soja. As plantas foram micorrizadas com Glomus etunicatum ou G. macrocarpum, com e sem o restabelecimento da comunidade microbiana do solo autoclavado. Um tratamento não micorrizado teve a comunidade microbiana restabelecida, enquanto outro foi mantido como controle absoluto. As plantas micorrizadas apresentaram maior crescimento e atenuação da toxidez de Mn, principalmente quando se restabeleceu a comunidade microbiana. Nesse caso, houve aumento da disponibilidade de Fe e diminuição da disponibilidade de Mn no substrato. O teor de P foi maior nas plantas...

Land use and vegetation cover on native symbionts and interactions with cowpea AGRIAMBI
Rocha,Beatriz C. F.; Santos,Enésia O. da S.; Santos,José G. D.; Takako,Adriana K.; Castro,Fabio J..
ABSTRACT Arbuscular mycorrhizal fungi and rhizobia are important components of agroecosystems and they respond to human interference. The objective of this study was to investigate native communities of those microorganisms in soil collected under the native forest, four pastures (Brachiaria brizantha, Panicum maximum, Arachis pintoi and Stylosanthes guianensis) and a fallow soil after maize cultivation, in interaction with cowpea (Vigna unguculata). The cowpea grew in a greenhouse until flowering. They were randomly distributed depending on soil, in five replications. The lowest mycorrhizal fungi sporulation and mycorrhizal root colonization occurred under the Panicum and forest soil. In the soils under forest and Stylosanthes, the cowpea did not exhibit...

Mycorrhizal Propagule Persistence in a Succession of Cereals in a Disturbed and Undisturbed Andisol Fertilized with Two Nitrogen Sources Chilean J. Agric. Res.
Cornejo,Pablo ; Rubio,Rosa ; Borie,Fernando .
Arbuscular mycorrhizal fungi (AMF) form symbiosis with plant roots, improving its establishment, nutrition, and tolerance to adverse soil conditions. In annual crop rotations, some aspects such as the type of N fertilizer and tillage system used can affect the AMF propagule density and its functionality in the following crop. To analyze the effect of the agronomic practices previously mentioned on the persistence and density of AMF propagules, a study in a succession of cereals was carried out. For this, soil previously cropped with wheat (Triticum aestivum L.) and fertilized with urea (NH4+) or sodium nitrate (NO3-) was disturbed in each case by simulating conventional tillage (CT) or maintained without disturbing, simulating no-tillage (NT). It was then...
