Resumo: | Symbiotic associations between tree species and mycorrhizal fungi may lead to better growth and nutrition of seedlings and so it becomes an important alternative to the establishment in the field, mainly in edaphic restriction areas, or to species of high nutritional demands. The cultivation of Tectona grandis (teca) in Brazil has been conducted in Cerrado areas with low fertility soils. The aim of the present study is to assess the effect of arbuscular mycorrhizal fungi (AMF) inoculation on the growth and mineral nutrition of teca seedlings. The experiment was performed in randomized blocks (six blocks), with four repetitions: 1) witness (inoculation-free mycorrhizal fungi); 2) inoculation with Rhizophagus clarus; 3) native AMF inoculum from twenty-year old teca cultivation in Mato Grosso state (MT inoculum); and 4) native AMF inoculum from clay extraction in Campos do Goytacazes (Campos inoculum). The plantlets were inoculated and cultivated in 6 dm³ pots for 135 days and assessed for stem hight and diameter of the stem base. Root samples were collected in order to assess the percentage of AMF colonization. The roots and the aerial part were dried, separately, in a forced air circulation oven at 65°C for 72 hours. Subsequently, the dry weight and the content of P, K AND S were determined. The mycorrhizal fungi inoculation, mainly the Rhizophagus clarus isolate and the Campos inoculum, has promoted better growth and K and S acquisition by teca seedlings. The inoculation using mycorrhizal fungi allowed greater nutrient use efficiency. |

No Brasil, o cultivo de Tectona grandis (teca) tem sido realizado em regiões do cerrado, em solos de baixa fertilidade. O presente trabalho objetivou avaliar o efeito da inoculação de fungos micorrízicos arbusculares (FMAs) sobre o crescimento e nutrição mineral de mudas de teca. O experimento foi realizado em delineamento em blocos casualizados (seis blocos), com quatro tratamentos: 1) Testemunha (sem inoculação de fungos micorrízicos); 2) Inoculação com Rhizophagus clarus; 3) Inóculo de FMAs obtido de plantio de teca no Mato Grosso (inóculo MT) com vinte anos; e 4) Inóculo de FMAs nativos de cava de extração de argila de Campos dos Goytacazes (inóculo de Campos). As plântulas foram inoculadas e cultivadas em vasos de 6 dm3, por 135 dias, e foram avaliadas quanto à altura e ao diâmetro da base do caule. Amostras de raízes foram coletadas para avaliação da porcentagem de colonização com FMAs. As raízes e a parte aérea foram secas, separadamente, em estufa de circulação forçada de ar (a 650C por 72 horas) e em seguida determinada a massa seca e teores de P, K e S. A inoculação com fungos micorrízicos, principalmente o isolado de Rhizophagus clarus e o inóculo de Campos, proporcionou maior crescimento e maior aquisição em relação a K e S das mudas de teca. A inoculação com os fungos micorrízicos proporcionou maior eficiência de utilização de nutrientes.Universidade Federal de Santa Maria2018-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3157210.5902/1980509831572Ciência Florestal; Vol. 28 No. 1 (2018); 25-34Ciência Florestal; v. 28 n. 1 (2018); 25-341980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31572/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessRodrigues, Luciana AparecidaBarroso, Deborah GuerraFiqueiredo, Fábio Afonso M.
