Resumo: | This study aimed to characterize Morphophysiologically native Rhizobia of Fabaceae forage Caatinga, Mimosa tenuiflora (Willd) Poiret, (Jurema preta), Macroptilium atropurpureum (OC.) Urb (Siratro) and Desmanthus pernambucanus (L.) Thellung (jureminha) in selected soils in areas of Caatinga located in the municipalities of Sertânia, Arcoverde and São Bento do Una- Pernambuco. Soil samples were collected at random in three areas in profile 0 to 20 cm depth, designed for the planting of Fabaceae, with the purpose of producing nodules. After obtaining the nodules and replication of the bacteria in the laboratory colonies were characterized as the time of growth and cultural characteristics of Rhizobia isolates. Tests were also made in vitro tolerance of Rhizobia isolated in different variations in salinity, temperature and pH. Based on physiological data we calculated the diversity indices, evenness, dominance and species richness, then dendrograms generated by the UPGMA algorithm. In cultural evaluation revealed that the isolates showed the hallmarks of flat lifting colonies, low to moderate production of exopolysaccharides, color ranging from white to cream and smooth surface in accordance with each individual. Physiological tests of the abiotic stress resistance showed that the natives isolated from Mimosa tenuiflora were more resistant when grown in soils from the municipality of Sertânia and isolates Macroptilium atropurpureum and Desmanthus pernambucanus had high resistance to high temperatures, regardless of place of farming. For Species diversity analysis can be seen that the Caatinga area evaluated in São Bento do Una showed lower species diversity. Native rhizobia in the areas of collections in Pernambuco semiarid feature high resistance to abiotic stress caused by temperatures up to 40 °C, variations in salinity and pH. |

Urb (Siratro) e Desmanthus pernambucanus (L.) Thellung (Jureminha), em áreas de Caatinga localizadas nos municípios de Sertânia, Arcoverde e São Bento do Una no Estado de Pernambuco. Foram coletadas amostras de solo nas três áreas no perfil de 0 a 20 cm de profundidade, destinadas para o plantio das fabáceas, com o propósito de produção de nódulos. Após a obtenção dos nódulos e replicação das bactérias em laboratório as colônias foram caracterizadas quanto ao tempo de crescimento e características culturais dos isolados. Também foram feitos testes de tolerância, in vitro, com diferentes variações de salinidade, temperatura e pH. Baseados nos dados fisiológicos foram calculados os índices de diversidade, equitabilidade, dominância e riqueza de espécies, em seguida gerados dendrogramas pelo algoritmo UPGMA. Na avaliação cultural observou-se que os isolados formaram colônias com elevação plana, moderada produção de exopolissacarídeos, coloração variando de creme a branca e superfície lisa de acordo com cada isolado. Os testes fisiológicos de resistência a estresses abióticos mostraram que os isolados nativos de Mimosa tenuiflora foram mais resistentes quando cultivados nos solos provenientes do município de Sertânia e que os isolados de Macroptilium atropurpureum e Desmanthus pernambucanus tiveram elevada resistência a altas temperaturas, independente do local de cultivo. A área de Caatinga avaliada em São Bento do Una apresentou menor diversidade de espécies em relação às demais áreas. Os rizóbios nativos das áreas de coletas no Semiárido pernambucano apresentam elevada resistência ao estresse abiótico causado por temperaturas até 40 °C, variação na salinidade e pH.Submitted by Mario BC (mario@bc.ufrpe.br) on 2017-02-20T12:53:49Z No. of bitstreams: 1 Suelane de Melo Dias.pdf: 1653730 bytes, checksum: 9a680e841961b44f37985e8341a0bd0a (MD5)Made available in DSpace on 2017-02-20T12:53:49Z (GMT).

description |
This study aimed to characterize Morphophysiologically native Rhizobia of Fabaceae forage Caatinga, Mimosa tenuiflora (Willd) Poiret, (Jurema preta), Macroptilium atropurpureum (OC.) Urb (Siratro) and Desmanthus pernambucanus (L.) Thellung (jureminha) in selected soils in areas of Caatinga located in the municipalities of Sertânia, Arcoverde and São Bento do Una- Pernambuco. Soil samples were collected at random in three areas in profile 0 to 20 cm depth, designed for the planting of Fabaceae, with the purpose of producing nodules. After obtaining the nodules and replication of the bacteria in the laboratory colonies were characterized as the time of growth and cultural characteristics of Rhizobia isolates. Tests were also made in vitro tolerance of Rhizobia isolated in different variations in salinity, temperature and pH. Based on physiological data we calculated the diversity indices, evenness, dominance and species richness, then dendrograms generated by the UPGMA algorithm. In cultural evaluation revealed that the isolates showed the hallmarks of flat lifting colonies, low to moderate production of exopolysaccharides, color ranging from white to cream and smooth surface in accordance with each individual. Physiological tests of the abiotic stress resistance showed that the natives isolated from Mimosa tenuiflora were more resistant when grown in soils from the municipality of Sertânia and isolates Macroptilium atropurpureum and Desmanthus pernambucanus had high resistance to high temperatures, regardless of place of farming. For Species diversity analysis can be seen that the Caatinga area evaluated in São Bento do Una showed lower species diversity. Native rhizobia in the areas of collections in Pernambuco semiarid feature high resistance to abiotic stress caused by temperatures up to 40 °C, variations in salinity and pH. |
