Effects of using different host plants on the detected biodiversity of arbuscular mycorrhizal fungi from an agroecosystem

Abstract: (Effects of using different host plants on the detected biodiversity of arbuscular mycorrhizal fungi from an agroecosystem). The influence of peanut (Arachis hypogaea L.), sorghum (Sorghum bicolor (L.) Moench) and maize (Zea mays L.) on the development and diversity of arbuscular mycorrhizal fungi (AMF) from an agrosystem was investigated. Soil collected from an agricultural field where maize had been grown was inserted into sowing holes, under the seeds of peanut, sorghum and maize those were subsequently gro… Show more

“…This procedure will influence directly on the amount of roots produced within each pot available for establishment of root colonization and consequently sporulation by different fungal species. Efficiency of Sorghum as a host plant for trapping AMF species has been well established (4,20) with soils from different geographical locations. Our results indicate that the homogenization of field soil inoculum allied with a C4 heavily seeded grass seems to be an appropriate approach to induce freshly produced spores of AMF species occurring in a large variety of tropical soils.…”

“…Legumes and grasses are some of the plant species that contribute most to multiplication of AMFs in the soil, whereas other common cover crops, such as oilseed radish, are non-mycotrophic (Gomide et al, 2009). However, little is known about the level of interference of monocropping or intercropping of cover crops on AMFs communities; cover crops may differ in their ability to select fungi and to affect their multiplication, which can cause changes in the AMFs community (Carrenho et al, 2002).…”

“…Segundo Allen et al (1995), algumas espécies de Glomus, Acaulospora e Scutellospora possuem ampla distribuição geográfica. Estudando os efeitos do uso de diferentes plantas hospedeiras na detecção da diversidade de FMA, Carrenho et al (2002) verificaram que amendoim e milho propiciavam o estabelecimento de membros de Acaulosporaceae, enquanto o sorgo favorecia o registro de espécies de Glomaceae.

“…As plantas de amendoim apresentaram os valores mais altos de colonização radicular. Resultado similar foi obtido por Carrenho et al (2002). Os níveis mais elevados de colonização radicular, verificados em amendoim, podem ser devidos à composição diferenciada dos exsudatos radiculares.…”
