Resumo: | http://dx.doi.org/10.5902/1980509813328Jatobá-Mirim species belongs to Fabaceae family and is distributed through Pantanal and Caatinga areas.Its wood is suitable for the construction and the manufacture of luxury furniture and is recommendedfor urban forestry and used to compose heterogeneous reforestation. Taking into account their potentialuse this work was developed with the objective of evaluating the effect of different temperatures on thegermination rate and initial root growth of Jatobá-Mirim seeds. The seeds used in this experiment wereharvested at ‘Cabeceira do Prata’ farm, located in ‘Jardim’ municipality, in Mato Grosso do Sul state, inSeptember 2009. The material collected was transported to the Laboratory of Research on Bio-diversityand Environmental Systems at Anhanguera-Uniderp University where the research was developed. Theseeds were submitted to constant temperatures of 20, 25, 30, 35 °C and alternated temperatures of 20-30 and 25-35 °C, in six treatments, kept in germination cameras of B.O.D type. The obtained results showthat the best temperatures for the seed germination are 30 oC (90%), 35 °C (97%) and 25-35 °C (90%),statistically equal, certifying that those temperatures are more efficient to promote the germination. Takinginto account the mean time for germination, germination speed index and dry matter production, constanttemperatures of 30 and 35oC are better and its results, statistically equal and higher than other treatments |

Sua madeira é indicada para construção civil e confecção de mobiliário de luxo, e a árvore é recomendada para arborização urbana e utilizada para a composição de reflorestamentos heterogêneos. Levando-se em consideração seu potencial de utilização, este trabalho foi desenvolvido com o objetivo de verificar o efeito de diferentes temperaturas sobre as taxas de germinação e crescimento radicular inicial de sementes de Jatobá-Mirim. As sementes utilizadas no experimento foram coletadas na Fazenda Cabeceira do Prata, Município de Jardim, Mato Grosso do Sul, em setembro de 2009. O material coletado foi transportado para o Laboratório de Pesquisa em Sistemas Ambientais e Biodiversidade da Universidade Anhanguera- Uniderp, no qual o experimento foi desenvolvido. As sementes foram submetidas a seis tratamentos, em temperaturas constantes, de 20, 25, 30 e 35°C e alternadas de 20-30 e 25-35°C em câmaras de germinação tipo BOD. Os resultados obtidos evidenciaram maior percentagem de germinação das sementes nas temperaturas de 30°C (90%), 35°C (97%) e 25-35°C (90%), estatisticamente iguais, indicando que estas temperaturas são mais eficazes em promover a germinação. Levando-se em consideração o tempo médio de germinação, índice de velocidade de germinação e produção de matéria seca, as temperaturas constantes de 30 e 35°C se destacam, sendo seus resultados estatisticamente iguais e superiores aos demais tratamentos.Universidade Federal de Santa Maria2014-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1332810.5902/1980509813328Ciência Florestal; Vol. 24 No. 1 (2014); 111-116Ciência Florestal; v. 24 n. 1 (2014); 111-1161980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/13328/8388Oliveira, Ademir Kleber Morbeck dePereira, Kelly Cristina Lacerdainfo:eu-repo/semantics/openAccess2017-04-13T17:54:15Zoai:ojs.pkp.sfu.ca:article/13328Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T17:54:15Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
