“…Non-significant effect (p<0.05) of mycorrhizal inoculation towards plant height may be attributed to the incorporation of biochar which has high phosphorus content-a limiting factor in the functions of AMF. This agrees with the results of Abbott and Robson (1991) who reported that mycorrhizal colonization in peanut plants was significantly depressed by adding Phosphorus. Sanchez and Salinas (1981) related the reduction in AM root colonization probably to high soil fertility level, which reduced the dependence of the plants on mycorrhizae and therefore restricted the development of these fungi to the root cortex.…”

Field experiment was conducted in 2013 and 2014 to evaluate growth performance of two tomato genotypes in response to biochar application and arbuscular mycorrhizal fungal (AMF) inoculation at the Teaching and Research Farm, Federal University of Agriculture, Abeokuta. The experiment was laid out in a split-split plot design with two tomato genotypes in the main plots, five levels of biochar application in the sub plots and two levels of AMF inoculation in the sub-sub plots. Data on plant height number of leaves and dry matter yields were generated and subjected to analysis of variance and significant means separated using Duncan's Multiple Range Test at 5 % level of significance. The result shows that mycorrhizal inoculation significantly increased (p< 0.05) the shoot dry matter yield (2935.8 kg ha -1 ) when compared with non-mycorrhizal plants, there is no significant difference in number of leaves, height and root dry matter yield. Application of 20 t ha -1 of biochar significantly increased (p< 0.05) the shoot dry matter yields and plant height while no significant differences were observed in number of leaves and root dry matter yield. From the results obtained it can be concluded that AMF can successfully be inoculated into biochar amended soil to improve the performance of tomato plant.

“…In this investigation, root colonization and sporulation were apparently correlated; however, these processes are not necessarily dependent on each other and previously published data are ambiguous (Abbott & Robson 1991, Douds 1994. For Acaulospora species it has been observed that intraradical development affects both the beginning of sporulation as well as the production of external hyphae (Gazey et al 1992).…”

(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 grown in sterilised quartz sand separately in plastic boxes for five months. After this period, collections of roots and rhizospheric soil were made to evaluate the percentages of root colonization (RC), number of spores (NS) and species of AMF. Peanut showed the highest average values for RC and NS: 24.5% and 547.8/100 g of soil, respectively. Maize had an average RC of 19.7% and 415.2 spores/100g soil. Sorghum showed the lowest values: 15.9% for average RC and 349.8 spores/100 g soil. A total of fourteen species of AMF were identified. Seven species were identified from peanut rhizospheres, Entrophospora colombiana being the most abundant and frequent. In sorghum rhizospheres, twelve species were found, Glomus geosporum was the dominant taxon in terms of number of spores and frequency. Ten species were detected in maize with Acaulospora longula being the most abundant and the most frequent. It was observed that peanut was the best plant for promoting the sporulation of AMF, while sorghum favoured the establishment of most AMF species, followed by maize. RESUMO (Efeitos do uso de diferentes plantas hospedeiras na biodiversidade detectada de fungos micorrízicos arbusculares de um agroecossistema). O objetivo deste trabalho foi estudar a influência de amendoim (Arachis hypogaea L.), sorgo (Sorghum bicolor (L.) Moench) e milho (Zea mays L.) sobre o desenvolvimento e diversidade de fungos micorrízicos arbusculares (FMA).Esporos de FMA, multiplicados anteriormente em milho, foram depositados sob sementes de amendoim, sorgo ou milho em caixas plásticas contendo areia de rio esterilizada. Cinco meses depois, amostras de raízes e solo rizosférico das três plantas hospedeiras foram coletadas para avaliar-se os parâmetros: colonização radical (CR), número de esporos (NE) e diversidade de espécies de FMA. Amendoim apresentou os valores mais altos de CR e NE: 24,5% e 547,8/100 g solo, respectivamente; milho teve valores menores para CR e NE: 19,7% e 415,2 esporos/100g solo, respectivamente; e sorgo apresentou em média 15,9% de CR e 349,8 esporos/100 g solo. Ao todo, foram isoladas e identificadas quatorze espécies de FMA. Sete foram verificadas em milho, sendo Entrophospora colombiana a mais abundante e freqüente. Em sorgo verificou-se 12 espécies, sendo Glomus geosporum o táxon dominante. Em milho foram isoladas dez espécies, sendo Acaulospora longula a mais abundante e freqüen-te. Pôde-se observar também que amendoim foi a planta que mais promoveu a esporulação dos FMA, enquanto sorgo favoreceu o estabelecimen...

The adoption of biological resources in agriculture may allow less dependence and better use of finite resources. This study aimed at evaluating the effects of inoculation with arbuscular mycorrhizal fungi native to the Brazilian Savannah associated with the application of mycorrhizal stimulant (7-hydroxy, 4'-methoxy-isoflavone), in the early growth of common bean and soybean. The experiment was carried out in a greenhouse, in a completely randomized design, with a 7 x 2 factorial arrangement, consisting of five arbuscular mycorrhizal fungi species, joint inoculation (junction of all species in equal proportions) and native fungi (without inoculation), in the presence and absence of stimulant. The following traits were evaluated: shoot dry matter, root dry matter, mycorrhizal colonization, nodules dry matter and accumulation of calcium, zinc and phosphorus in the shoot dry matter. The increase provided by the arbuscular mycorrhizal fungi and the use of stimulant reached over 200 % in bean and over 80 % in soybean plants. The fungi Acaulospora scrobiculata, Dentiscutata heterogama, Gigaspora margarita and Rhizophagus clarus, for bean, and Claroideoglomus etunicatum, Dentiscutata heterogama, Rhizophagus clarus and the joint inoculation, for soybean, increased the dry matter and nutrients accumulation.
