“…In general, most plants absorb nitrate and ammonium to undergo rapid development in nitrate-rich environments (Sun, Yu, & Hu, 2017;Yu, Ma, Sun, Zou, Lin, Fu, & Fu, 2018). However, some plant species require large amounts of nitrate in the initial phases of their development (Vitorazi Filho et al, 2012), which drastically reduces the ammonium concentration in the soil.…”

The present work aimed to evaluate the effects of encapsulated microorganisms on seedlings of Eugenia stipitata, popularly known as araçá-boi, to evaluate the interaction between the inoculum and encapsulating agents such as clay and alginate. The experiment was carried out in a completely randomized design using a 3×2 factorial scheme. The treatments were control, inoculum, clay without microbial inoculum, clay with microbial inoculum, alginate without microbial inoculum, and alginate with microbial inoculum. The seedlings were grown under nursery conditions over a period of 3 months. No treatment increased the height, stem diameter, shoot dry matter or root dry matter of the araçá-boi seedlings. The use of alginate increased the ammonium content compared to the clay and control treatments. Alginate and clay increased the nitrate content in relation to the control. Alginate increased the total number of bacteria in relation to the clay and control treatments. The application of inoculum combined with alginate increased the nitrate content only in relation to the clay and control treatments. Although the application of inoculum promoted an increase in the nitrate content compared to the uninoculated treatments, there was no effect for the other parameters analyzed. The results suggest that clay and alginate encapsulating agents with the presence or absence of microorganisms may improve some soil parameters.

“…This result shows that the change in physiological variables was related to the formation of mycorrhizal association and its benefits. Several studies report significant correlations between growth parameters, nutrient content and percentage of colonization, as in sweet passion fruit plants Vitorazi Filho et al (2012), melon seedlings Silva Júnior et al (2012) and cedar seedlings.

The inoculation of coffee plants with arbuscular mycorrhizal fungi (AMF) may influence some of its physiological parameters, promoting benefits in the growth of newly planted coffee. The objective of this work was to evaluate the physiological responses of different cultivars of Coffea arabica inoculated with arbuscular mycorrhizal fungi. The experiment was conducted in a vegetation house in Diamantina, state Minas Gerais. The design was in randomized blocks, in a 3 x 4 factorial scheme, with four replications. The factors were composed of coffee seedlings of Rubi (MG 1192), Mundo Novo (IAC 379-19) and Catuaí Vermelho (IAC 144) cultivars, inoculated or not with FMA Rhizophagus clarus, Acaulospora colombiana and Mix composed by R. clarus and A. colombiana. At 150 days after transplantation, physiological characteristics such as photosynthetic rate, internal carbon concentration, stomatal conductance, transpiration rate, water use efficiency, internal carbon / atmospheric carbon ratio and percentage of mycorrhizal colonization were evaluated. AMF inoculation affected positively the physiology of coffee plants, increasing photosynthetic rate (A), stomatal conductance (Gs), transpiration, carbon consumed (∆CO 2), water use efficiency (EUA) and percentage of mycorrhizal colonization (%), as well as reducing the internal carbon concentration (Ci) for all combinations of AMF cultivars and species. The cultivar Rubi, when inoculated with R. clarus or Mix, obtained a higher percentage of colonization. The physiological activity of coffee plants is altered by symbiotic association, and their responses varied between AMF species and cultivars.

“…An alternative to the preparation of these seedlings is to use AMFs, which have contributed to reduce the production time of several fruit trees such as citrus (Altoé et al, 2008), yellow passion fruit (Cavalcante et al, 2001;Cavalcante et al, 2002), sweet passion fruit (Anjos et al, 2005;Vitorazi et al, 2012), papaya (Lima et al, 2011) and cashew (Weber et al, 2004), in addition to reducing phosphate fertilization (Riter Netto et al, 2014).…”

The success of star fruit cultivation deployment begins with the use of good quality seedlings Thus the inoculation of mycorrhizal fungi in culture seedling can be an alternative, since it was found success in both growth as nutritional aspect fruit species. In this sense, the aim of this study was to evaluate the effects of arbuscular mycorrhizal fungi (AMFs) on growth and mineral composition of star fruit seedlings, cultivated under different doses of phosphorus (P). The experiment was conducted in a greenhouse and the experimental design used was randomized blocks in a 3 x 4 factorial scheme, with three microbiological treatments (without inoculation, Rhizofagus clarum, Glomus etunicatum) and four doses of P (0, 50, 100 and 200 mg kg -1 soil) with four replications. Plants were harvested four months after sowing for biometric and nutritional analysis. In the soil without phosphate fertilization, R. clarum, provided increments of 49% in height, 99% in dry matter production and 86, 129 and 108% in the contents of N, K, and Ca, respectively, in relation to the control. Regardless of phosphate fertilization, the content of P, Mg, and S in the dry matter weight was 19.2, 17.6 and 23.6% higher in the treatment inoculated with R. clarum, in relation to the control. Mycorrhizal dependence of star fruit tree varied according to fungus species and the P dose used, being greater when the fungus R. clarum was used in absence of P.Key words: Averrhoa carambola L.; mineral composition; mycorrhiza Fungos micorrizicos arbusculares e adubação fosfatada em mudas de caramboleira RESUMO O sucesso da implantação do cultivo da caramboleira inicia-se com a utilização de mudas de boa qualidade, nessa linha a inoculação de fungos micorrizicos em mudas da cultura pode ser uma alternativa, visto que foi verificado sucesso tanto no crescimento como em aspecto nutricionais em espécies frutíferas. Nesse sentido, objetivou-se com esse trabalho avaliar a inoculação de fungos micorrízicos arbusculares (FMAs) no crescimento e composição mineral das mudas de caramboleira, cultivadas com doses de fósforo (P). O delineamento estatístico utilizado foi de blocos ao acaso, num fatorial 3 x 4, com três tratamentos microbiológicos (sem inoculação, Rhizofagus clarum, Glomus etunicatum) e quatro doses de P (0, 50, 100 e 200 mg kg -1 de solo) e quatro repetições. As plantas foram colhidas aos quatro meses após a semeadura para análises biométricas e nutricionais. No solo sem adubação fosfatada, o fungo R. clarum proporcionou incrementos de 49% na altura, 99% na produção de massa de matéria seca e de 86, 129 e 108% nos conteúdos de N, K e Ca, respectivamente, em relação ao controle. Independente da adubação fosfatada, o conteúdo de P, Mg e S na massa de matéria seca foi 19,2, 17,6 e 23,6% maior no tratamento inoculado com R. clarum, em relação ao controle. A dependência micorrízica da caramboleira variou de acordo com a espécie de fungo e a dose de P utilizada, sendo maior quando se utilizou o fungo R. clarum na ausência de P. Palavras-chave:Aver...
