Resumo: The Adesmia species found in Rio Grande do Sul and Santa Catarina have high nutritional quality and may be used in breeding programs of native grasslands. The aim of this study was to evaluate the growth promotion in Adesmia species by rhizobacteria producing indolyl acetic acid (IAA). Seven isolates of bacteria from nodules of Adesmia latifoliafrom the Epagri collection of rhizobacteria were used. These were analyzed for production of indolyl acetic acid and promotion of plant growth in A. latifolia, A. psoraleoides, A. riograndensis and A. tristis. The results showed a variable production of IAA by different isolates used. The isolates produced different effects in promoting the growth of different species of Adesmia. The bacterial strains used are specific for nodulation in A. latifolia. Leaf number and length of twoleaved shoots are not affected by the isolates used in this study. The effects of bacteria isolated from nodules in promoting growth varied depending on the interaction with the different species of Adesmia. EEL0710 strain promotes increased growth in A. latifolia, A. psoraleoides and A. tristis. EEL1710A strain promotes increased growth in A. riograndensis. Thelevel of endogenous IAA has no direct relationship in promoting the growth of Adesmia species.

As espécies de Adesmia encontradas no Rio Grande do Sul e em Santa Catarina apresentam alta qualidade forrageira e podem ser utilizadas em programas de melhoramento de campos nativos. O objetivo deste trabalho foi avaliar a promoção do crescimento em espécies de adésmia por rizobactérias produtoras de ácido indolacético (AIA). Foram utilizados sete isolados de bactérias de nódulos de adésmia e pertencentes à coleção de rizobactérias da Epagri. Avaliaram-se a produção de AIA in vitro e a promoção de crescimento vegetal pelos isolados em Adesmia latifolia, A. psoraleoides, A. riograndensis e A. tristis. Os isolados bacterianos utilizados são específicos para nodulação em A. latifolia.Os resultados obtidos demonstraram uma produção variável de AIA pelos diferentes isolados. O número de folhas bifoliadas e o comprimento dos brotos não são afetados pelos isolados utilizados neste trabalho. Os efeitos dos isolados de bactérias de nódulos na promoção do crescimento variaram em função da interação com as diferentes espécies deadésmia. O isolado EEL0710 promove maior crescimento em Adesmia latifolia, A. psoraleoides e A. tristis. O isolado EEL1710Apromove maior crescimento em A. riograndensis. O nível endógeno de ácido indolacético não apresenta uma relação direta na promoção do crescimento das espécies de Adesmia Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/676Agropecuária Catarinense Journal; Vol. 24 No. 1 (2011); 60-64Agropecuária Catarinense; v. 24 n. 1 (2011); 60-642525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/676/577Copyright (c) 2020 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessMuniz, Alexsander WestphalDalagnol, Gilberto LuizWordell Filho, João Américode Sá, Enilson Luiz Saccol de Sá2021-02-17T14:35:51Zoai:ojs.publicacoes.epagri.sc.gov.br:article/676Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-02-17T14:35:51Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
