Resumo: | The objective of this research was to study the maturation process of Erythrina crista-galli L. seeds to determinate the ideal collect period. In this regard, six trees located in Santa Maria - RS were used from which were collected weekly, starting with fruits until seeds maturation. The parameters observed to indicate seed maturation were: fruit and seed dimensions; seed fresh and dry matter; moisture content, germination test (expressed by normal seedlings) and vigor (first count of germination). The seeds dimensions were highest in the same period of maximum germination, with values 167.0, 8.72 and 8.60 mm of length, thickness and width, respectively. The seeds moisture content could be used to indicate the seeds maturation, and also seeds fresh and dry matter with maximum values on the eighth week, 31.6 %, 0.693 and 0.474 g/seed, respectively. The Erythrina crista-galli has dormant seeds after physiological maturation, with low percentage of germination on the tenth week after anthesis. The point of physiological maturation in Santa Maria - RS conditions happens on the eighth week after anthesis, with germination percentage of 50%, which were indicate by all parameters observed. |

Para tanto, foram utilizadas seis árvores matrizes na cidade de Santa Maria (RS), de onde foram feitas coletas semanais, começando com o surgimento dos frutos até sua deiscência e posterior maturação das sementes. Os parâmetros indicadores da maturação das sementes observados foram: dimensão de frutos e sementes; massa fresca e massa seca das sementes; teor de água, teste de germinação (expresso em plântulas normais) e vigor (primeira contagem de germinação). A dimensão máxima das sementes ocorreu no período máximo de germinação, com valores de 167,0, 8,72 e 8,60 mm para comprimento, espessura e largura, respectivamente. O teor de água pode ser utilizado como indicativo de maturidade das sementes, assim como massa fresca e massa seca com valores máximos na oitava semana, 31,6 %, 0,693 e 0,474 g/semente, respectivamente. As sementes de Erythrina crista-galli apresentam dormência após a maturação fisiológica, com baixa percentagem de germinação na décima semana após a antese. O ponto de maturidade fisiológica, nas condições de Santa Maria - RS ocorre na oitava semana após a antese, com germinação de 50%, devido a todos os parâmetros observados terem assim indicado.Universidade Federal de Santa Maria2011-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/274210.5902/198050982742Ciência Florestal; Vol. 21 No. 1 (2011); 9-16Ciência Florestal; v. 21 n. 1 (2011); 9-161980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2742/1668Lazarotto, MaríliaBeltrame, RafaelMuniz, Marlove Fátima BriãoBlume, Elenainfo:eu-repo/semantics/openAccess2017-05-04T11:23:08Zoai:ojs.pkp.sfu.ca:article/2742Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-04T11:23:08Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
