Última The effect of different soil properties on arbuscular mycorrhizal colonization of peanuts, sorghum and maize Acta Botanica Carrenho,Rosilaine; Trufem,Sandra Farto Botelho; Bononi,Vera Lúcia Ramos; Silva,Eraldo Schunk. Arbuscular mycorrhizal fungi (AMF) are important for plant growth since they increase mineral influx. However, symbiosis efficiency is affected by many environmental factors. This study evaluated the effects of different treatments (+/- phosphorus; +/- liming; +/- organic matter; field, sandy or clayey soil textures) on root colonization (RC) of peanuts, sorghum and maize. The combination of these resulted in seventy-two treatments. The 2×2×2×3×3 factorial experiment was laid out in a randomized design. All data were subjected to variance analysis and the means were compared (Tukey at P<0.05). Three months after seed germination, roots were collected to evaluate the percentage of RC. Results showed that soil texture and liming were the most important... Tipo: Info:eu-repo/semantics/article Palavras-chave: Mycorrhiza; Liming; Soil texture; Organic matter; Phosphorus.

A large number of propagules and a broad spectrum of species are two important components of ecosystem (including agroecosystem) sustainability. Previous studies carried out in temperate areas showed that repeated monoculture leads to a decrease in the species abundance of arbuscular mycorrhizal fungi (AMF). This study evaluated the influence of maize monoculture and its agricultural practices on AMF during three consecutive cropping years in a Brazilian field. At the end of each cycle, soil and root samples were evaluated for species composition, spore populations and root colonization by AMF. The AMF community present during this period was scored according to the Spearman rank correlation and Principal Components Analysis. The mean percent root...
