Resumo: | Found in different types of soils and climates, the legumes have a wide geographical distribution. They have a rich and important taxonomic diversity that places them as one of the largest families in numbers of species, and, for the most part, provide symbiosis with nitrogen-fixing bacteria, commonly known as rhizobia. Forage legumes also have direct effects on animal productivity due to their nutritional value, since participating in the animal diet contribute to increase the gain in weight as well as contribute more nutrients to the diet, besides being able to minimize productivity costs when compared with exclusive grass pastures, submitted to fertilization with mineral nitrogen. In this sense Desmanthus, a native genus of Brazil, presents as an interesting alternative as a source of forage legumes for the semi-arid tropics. Thus, this work aims to evaluate nitrogen fixation potential and symbiotic compatibility of rhizobial strains from the semi - arid region of Pernambuco with four accessions of Desmanthus that were differentiated through molecular marker ISSR. These were evaluated in polyethylene bags in a greenhouse in a randomized complete block design, with four replications, evaluating shoot dry matter (MSPA), root (MSSR), number of nodules (NN), nodule weight (MSN), accumulation (ANPA), and relative efficiency (ER), submitted to analysis of variance and the Scott Knott test at 5% probability. Each genotype of Desmanthus obtained greater fixation with certain isolates specifically, the genotypes 31D and 13AU were those that presented greater capacity of fixation of nitrogen, in relation to the other evaluated genotypes. |

Avaliação do potencial fixador de nitrogênio de genótipos de Desmanthus. 2017. 62 f. Dissertação (Programa de Pós-Graduação em Melhoramento Genético de Plantas) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/6942Found in different types of soils and climates, the legumes have a wide geographical distribution.

Elas apresentam uma rica e importante diversidade taxonômica que as colocam como uma das maiores famílias em números de espécies, além de, em sua maior parte, proporcionarem simbiose com bactérias fixadoras de nitrogênio, comumente conhecidas como rizóbio. As leguminosas forrageiras também possuem reflexos diretos sobre a produtividade animal, devido ao seu valor nutricional, pois participando da dieta animal contribuem para incrementar o ganho em peso bem como aportam maior quantidade de nutrientes à dieta, além de poder minimizar os custos de produtividade quando comparados com pastagens de gramínea exclusiva, submetidas à adubação com nitrogênio mineral. Nesse sentido o Desmanthus, gênero nativo do Brasil, apresenta-se como uma alternativa de grande interesse como fonte de leguminosas forrageiras para os trópicos semiáridos. Sendo assim, este trabalho visa avaliar o potencial fixador de nitrogênio e compatibilidade simbiótica de estirpes rizobianas provenientes do semiárido pernambucano com quatro acessos de Desmanthus que foram diferenciados através do marcador molecular ISSR. Estes foram avaliados em sacos de polietileno em casa de vegetação, em blocos casualizados, com quatro repetições, avaliando matéria seca da parte aérea (MSPA), raiz (MSSR), número de nódulos (NN), peso de nódulo (MSN), acúmulo de N da parte aérea (ANPA), e eficiência relativa (ER), submetidos à análise de variância e ao teste de Scott Knott a 5% de probabilidade. Cada genótipo de Desmanthus obteve maior fixação com determinados isolados especificamente, os genótipos 31D e 13AU foram os que apresentaram maior capacidade de fixação de nitrogênio, em relação aos demais genótipos avaliados.Submitted by Mario BC (mario@bc.ufrpe.br) on 2017-05-24T13:53:19Z No. of bitstreams: 1 Jacilene Angela de Santana.pdf: 811747 bytes, checksum: f952ec4fb4677ced04329668e947dd37 (MD5)Made available in DSpace on 2017-05-24T13:53:19Z (GMT).
