Resumo: | Blueberries are temperate fruit species of great economic importance that has stood out in Southern Brazil. The objectives of this study were to evaluate the influence of arbuscular mycorrhizal fungi (AMF) on the production of plantlets of blueberry, as well as isolate and identify these fungi from the orchards in the South - RS. Samples were collected from soil and roots in experimental and commercial of blueberry orchards in the municipalities Pelotas, Morro Redondo and Jaguarão and ecological indexes used as a measure populations in orchards in the study and principal components analysis to assess the physical and chemical soil in relation to the AMF. We identified 18 different morphotypes of spores. The percentages of root colonization with AMF were high, ranging from 40 to 80%. Since the varieties in commercial orchard located in the city of Morro Redondo city were the most colonized in relation to others. The greatest number of spores found in O'Neal in the orchard from Micaela. The relative abundance and the highest Shannon diversity index (H ') and richness (R) were found in the older areas of cultivation, old orchard at Embrapa (EPV) and the commercial orchard in the Morro Redondo city (MR). The relative frequency shows the prevalence of species of the genus Glomus and Acaulospora in all orchards. The dominance evaluated by the Simpson index (Is) showed the same trend as the Shannon diversity and richness. Among the chemical parameters of soil, there was a high correlation of AMF species with varying pH, V (%), P and sand. AMF isolates for the production of seedlings were provided by Bank of species of the Department of Horticulture and Forestry at UFRGS. Were tested four species of AMF (Glomus clarum, Glomus etunicatum, Gigaspora margarita and Scutellospora heterogama) on the production of cultivars Woodard and Bluegem. The AMF would have positive effects in the nursery, particularly Gigaspora margarita which provided better nutrition, and higher biomass of plants growing Woodard and Glomus etunicatum Bluegem for cultivation. The efficiency of the mycorrhizal symbiosis of blueberry cultivars, depends on the interaction specifies AMF X host. |

Os objetivos desse trabalho foram avaliar a influência de fungos micorrízicos arbusculares (FMA) na produção de mudas micropropagadas de mirtilo, assim como isolar e identificar esses fungos oriundos dos pomares da região Sul - RS. Foram coletadas amostras de solo e raízes em pomares comerciais e experimentais de mirtilo dos municípios de Pelotas, Morro Redondo e Jaguarão e utilizados índices ecológicos como forma de avaliar as populações nos pomares em estudo e a análise de componentes principais para avaliar os atributos físicos e químicos do solo em relação aos FMAs. Foram identificadas 18 diferentes morfotipos de esporos de FMA. As porcentagens de colonização radicular com FMA foram elevadas, variando de 40 a 80%. Sendo que as variedades localizadas no pomar comercial do município do Morro Redondo foram as mais colonizadas em relação às demais. O maior número de esporos foi encontrado na variedade O‟Neal no pomar comercial da Micaela. A abundância relativa e os maiores índices de diversidade Shannon (H‟) e riqueza (R) foram encontrados nas áreas mais velhas de cultivo, pomar velho experimental da Embrapa (EPV) e do pomar comercial do município Morro Redondo (MR). A frequência relativa demonstra a prevalência de espécies do gênero Glomus e Acaulospora em todos os pomares. A dominância avaliada pelo índice de Simpsom (Is) apresentou a mesma tendência da diversidade de Shannon e da riqueza. Entre os parâmetros químicos do solo, houve uma alta correlação das espécies de FMA com as variáveis pH, V(%), P e areia. Os isolados de FMAs para a produção de mudas foram cedidos pelo banco de espécies do Departamento de Horticultura e Silvicultura da UFRGS. Testaram-se quatro espécies de FMAs (Glomus clarum, Glomus etunicatum e Scutellospora heterogama e Gigaspora margarita) sobre a produção de mudas das cultivares Woodard e Bluegem. Os FMAs proporcionaram efeito positivo na produção das mudas, em especial Gigaspora margarita que proporcionou melhor nutrição e maior incremento na biomassa nas plantas da cultivar Woodard e o Glomus etunicatum para a cultivar Bluegem. A eficiência da simbiose dos FMAs em cultivares de mirtilo, depende da interação especifica FMA X hospedeiro.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em AgronomiaUFPelBRFaculdade de Agronomia Eliseu MacielVaccinium sp.EndomicorrizaMicropropagaçãoMudasVaccinium sp.EndomycorrhizalMicropropagationSeedlingsCNPQ::CIENCIAS AGRARIAS::AGRONOMIADiversidade de fungos micorrízicos arbusculares em pomares e crescimento de mudas micropropagadas de mirtileiroDiversity of arbuscular mycorrhizal fungi in orchards and seedling growth ofmicropropagated blueberryinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_daniela_da_hora_farias.pdfapplication/pdf867696http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1136/1/dissertacao_daniela_da_hora_farias.pdf75997246f8d586086ba6e82e5a50c2edMD51open accessTEXTdissertacao_daniela_da_hora_farias.pdf.txtdissertacao_daniela_da_hora_farias.pdf.txtExtracted Texttext/plain133106http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1136/2/dissertacao_daniela_da_hora_farias.pdf.txt663ec57a553602fe37492f8ec5f707e3MD52open accessTHUMBNAILdissertacao_daniela_da_hora_farias.pdf.jpgdissertacao_daniela_da_hora_farias.pdf.jpgGenerated Thumbnailimage/jpeg1444http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1136/3/dissertacao_daniela_da_hora_farias.pdf.jpg16e0d1dd01a62fcddeda9dd0901cc1abMD53open access123456789/11362023-04-19 10:41:11.526open accessoai:guaiaca.ufpel.edu.br:123456789/1136Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-04-19T13:41:11Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
