Resumo: | http://dx.doi.org/10.5902/198050988457In tropical ecosystems, little is known about the relationship between arbuscular mycorhizal fungi (AMF) and the host genetic variability, especially among tree species. This study aimed to examine the response of 19 progenies of jatobá-do-cerrado (Hymenaea stignocarpa Mart. Ex. Hayne) inoculated with AMF, the root colonization and seedlings early growth were evaluated, growing in cultivated in subsoil from the “loading area”, under greenhouse conditions. The seedlings, germinated in the laboratory, were transferred to plastic bags containing subsoil and sand mixture (4:1). For the inoculation, each replicate received 100 g of soil (with about 48 spores of AMF) from a preserved “Cerrado” area, to reintroduce microorganisms. After 120 days, the mycorrhiza colonization (COL), the number of spores of AMF, the plant height (PH), the weight of shoot dry matter (SDM) and the root fresh matter (RFM) were assessed. The highest values of COL, SDM and RFM were observed in the progenies JC7, JC18, JC29, JC27 and JC14; the JC7 and JC18 also increased number of spores. There were significant and positive correlations between COL and the others variables (AP, NE, RFM and SDM, and between RFM and other variables (NE, AP and SDM). The conclusion is that, there is variability among the genotypes of Hymenaea stignocarpa growth (AP MFSR and DMAP) and mycorrhization (COL and NE), with emphasis on two progenies (JC7 and JC18), that showed the highest values, which can be resulted of a greater affinity to strains of AMF- soil inoculum. |

O presente trabalho teve como objetivo verificar a resposta de 19 progênies de jatobá-do-cerrado (Hymenaea stignocarpa Mart. ex. Hayne) à inoculação, por meio da colonização micorrízica e o crescimento inicial de mudas cultivadas em subsolo de área decapitada, em condições de casa de vegetação. As plântulas, germinadas em laboratório, foram transferidas para sacos plásticos contendo 3 kg da mistura subsolo e areia (4:1). Para a inoculação, cada repetição recebeu 100 gramas de solo (com cerca de 48 esporos de FMA) proveniente de uma área de cerrado preservado. Aos 120 dias avaliou-se a colonização micorrízica (COL), o número de esporos (NE) de FMA, a altura de planta (AP), o peso da massa seca da parte aérea (MSPA) e massa fresca do sistema radicular (MFSR). Os maiores valores para COL, MSPA e MFSR foram observados nas progênies JC7, JC18, JC29, JC27 e JC14, sendo que as JC7 e JC18 proporcionaram, também, os maiores números de esporos de FMA. Houve correlação significativa e positiva entre COL e demais variáveis (AP, NE, MSPA e MFSR) e entre MFSR e demais variáveis (NE, AP e MSPA). Conclui-se que existe variabilidade entre os genótipos de Hymenaea stignocarpa no crescimento (AP, MSPA e MFSR) e micorrização (COL e NE), com destaque para duas progênies (JC7 e JC18), pelos valores mais elevados, as quais são resultados de uma maior afinidade aos isolados de FMA presentes no solo-inóculo.Universidade Federal de Santa Maria2013-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/845710.5902/198050988457Ciência Florestal; Vol. 23 No. 1 (2013); 233-243Ciência Florestal; v. 23 n. 1 (2013); 233-2431980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/8457/5137Faria, Tiago MendesScabora, Márcia HelenaMaltoni, Kátia LucieneCassiolato, Ana Maria Rodriguesinfo:eu-repo/semantics/openAccess2017-04-17T19:03:01Zoai:ojs.pkp.sfu.ca:article/8457Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T19:03:01Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
