1. High rates of agricultural gypsum affect the arbuscular mycorrhiza fungal community and coffee yield
ABSTRACT High rates of agricultural gypsum, above the recommended levels, have been used on a regular basis to deepen plant roots and to alleviate recurrent water stress in Cerrado areas. However, very little is known about the consequences of this practice to arbuscular mycorrhizal fungi (AMF). Therefore, the objective of this study was to evaluate whether

2. Early changes in arbuscular mycorrhiza development in sugarcane under two harvest management systems
Sugarcane (Saccharum spp.) is grown on over 8 million ha in Brazil and is used to produce ethanol and sugar. Some sugarcane fields are burned to facilitate harvesting, which can affect the soil microbial community. However, whether sugarcane pre-harvest burning affects the community of arbuscular mycorrhizal fungi (AMF) and symbioses development is not known

3. Colonization of Greek olive cultivars' root system by arbuscular mycorrhiza fungus: root morphology, growth, and mineral nutrition of olive plants
Rooted leafy cuttings of three Greek olive (Olea europaea L.) cultivars (Koroneiki, Kothreiki and Chondrolia Chalkidikis) were grown for six months in three soil types, in an experimental greenhouse, in order to investigate: i) if their root system was colonized by arbuscular mycorrhiza fungus (AMF) genus and, ii) if genotypic differences concerning growth a

4. Changes in the accumulation of shikimic acid in mycorrhized Capsicum annuum L. grown with application of glyphosate and phosphorus
When glyphosate is added to the soil, it is absorbed by roots and transported by xylem causing growth inhibition in plants. Mycorrhiza is the beneficial association between roots of most plants and soil fungi. The methylphosphonic group of the glyphosate could compete with inorganic phosphates for sorption sites in the soil. The aim of this work was to study

5. Interrelação bactérias (MHB) e FMA : estratégia para estimular a eficiência simbiótica e micorrização de sabiá. / Bacteria (MHB) and FMA interrelation : a strategy to stimulate the symbiotic efficiency and mycorrhizal of sabiá.
A utilização de plantas associadas simbioticamente, com bactérias fixadoras de N2 e fungos micorrízicos arbusculares (FMA), constitui uma estratégia eficiente para acelerar a recuperação de áreas impactadas além de reduzir consideravelmente os custos com a mesma. O conceito de mycorrhiza helper bacteria (MHB) tem sido introduzido e discutido devido

6. Estudo da colonizaÃÃo micorrÃzica arbuscular no desenvolvimento de minirosa em um Neossolo QuartzarÃnico do municÃpio de EusÃbio - CE / Study of arbuscular mycorrhizal colonization on the development of rose miniature in a Neosoil Quartzarenic of the EusÃbio county in Cearà state
O Estado do Cearà vem se destacando na Ãrea de produÃÃo de flores e plantas ornamentais nos Ãltimos anos e tem apresentado crescimento em vÃrios aspectos, influenciando, dessa maneira, no desenvolvimento da economia cearense. No entanto, apesar da grande importÃncia econÃmica das rosas no Cearà como tambÃm em outras regiÃes do Brasil, hà carÃnci

7. Contribuição da micorriza arbuscular na resposta das culturas à calagem e adubação fosfatada em solos de cerrado.
ABSTRACT: The crop production in the cerrado soils may be improved when high amounts of lime and phosphate fertilizers are used. An economical management alternative of these inputs involves biological processes as the arbuscular mycorrhiza. The presence of arbuscular mycorrhizal fungi in the soil and the consequent root colonization cause an alteration in t

8. Impacto do sistema de plantio direto na diversidade de espécies de fungos micorrízicos arbusculares nativos em solo de cerrado.
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,

9. Manejo da micorriza arbuscular em sistemas integrados de lavoura e pastagens no Cerrado.
ABSTRACT: The arbuscular mycorrhizal fungi community is low in Cerrado soils and it gradually increases with soil cropping. Rotations of crops and of production systems stimulate propagation of those fungi in the soil, mycorrhiza formation and its effects in the plants. The crop-pasture integrated systems are well recommended, as pastures favors spores multi

10. Contribuição da micorriza arbuscular para a produtividade e sustentabilidade nos sistemas de produção com plantio direto e convencional no Cerrado.
ABSTRACT: The development of a sustainable agriculture requires the use of agricultural practices that involve a minimum soil tillage. The cropping systems change the dynamics of native arbuscular mycorrhizal fungi and these, on the other hand, determine the contribution of arbuscular mycorrhiza on crop responses to lime and fertilizers and on the efficiency

11. Efeito de diferentes comunidades de fungos micorrízicos arbusculares no crescimento de plantas nativas pertencentes aos diferentes grupos ecológicos da sucessão
The aim of this work was to evaluate the response of nine plant species belonging to different ecological successional groups to communities of arbuscular mycorrhizal fungal (AMF) from different plant successional stages. The experiment was carried out in greenhouse with three gramineous species, three pioneer woody species, and three late successional woody

12. Arbuscular mycorrhizal fungi communities in soil and sugarcane roots / Comunidades de fungos micorrízicos arbusculares no solo e raízes de cana-de-açúcar
Arbuscular mycorrhizal fungi (AMF, Glomeromycota) form mutualistic symbioses with most land plants. AMF hypha generally grow through the soil and colonize the cortical tissue of the plant roots. However, it is not known whether the most abundant species in the soil, determined based on the morphology of asexual spores are the most abundant inside the roots,
