Resumo: | http://dx.doi.org/10.5902/198050989280This study aimed to elucidate the time of occurrence of flowers and fruits and the external and internal morphology of the flower, fruit and seed, and seedling and external changes of Diatenopteryx sorbifolia Radlk (Sapindaceae). The collection of botanical material and phenological observations were made on trees headquarters, located in the municipality of Frederico Westphalen, Rio Grande do Sul state, between March 2007 and March 2010. The study was conducted at the Seed Laboratory of the Department of Forest Sciences, Federal University of Santa Maria, RS state. The species flowered from September to October. The annual fruiting occurs from November to January, having anemochorous dispersion. There were irregularities in the production of fruits as the years and there is no synchronization between headquarters during the phenophases. The species has inflorescence thyrsus, pleiotirso, with small white flowers in color, hermaphrodites with ovarian super sincarpico, and bicarpelar uniovular, as well as male unisexual flowers. The fruit of siples, dry, indehiscent, brown color, is the type esquisocarpaceo, consisting of samarideos containing one to two seeds, ovoid, brown color, exalbuminate with axial embryo and fleshy cotyledons. The germination process started from the second day after sowing, germination is epigeal type. After 18 days, the seedling phanerocotyledonal is formed. The changes in conditions to be studied, are formed three months after sowing. The phenological characterization is morphological information that is relevant for the field identification of species, seed collection and analysis, as well as the production of seedlings. |

A coleta do material botânico e as observações fenológicas foram realizadas em árvores matrizes, localizadas em remanescentes, no Município de Frederico Westphalen, RS, entre março de 2007 a março de 2010. O trabalho foi conduzido no Laboratório de Sementes do Departamento de Ciências Florestais, Universidade Federal de Santa Maria, RS. A espécie floresceu de setembro a outubro. A frutificação anual ocorreu de novembro a janeiro, tendo dispersão anemocórica. Houve irregularidade na produção de frutos conforme os anos, não havendo sincronismo entre matrizes durante as fenofases. A espécie possui inflorescência do tipo tirso, pleiotirso, com pequenas flores de coloração branca, hermafroditas com ovário súpero, sincárpico, bicarpelar e uniovular, como também flores unissexuais masculinas. O fruto simples, seco e indeiscente, de coloração castanha, é do tipo esquisocarpáceo, constituído por dois samarídeos contendo de uma a duas sementes, de formato ovoide, coloração castanha, exalbuminosas, com embrião axial e cotilédones carnosos. O processo germinativo iniciou a partir do 2° dia após a semeadura, sendo a germinação do tipo epígea. Após 18 dias, a plântula fanerocotiledonar está formada. A muda, nas condições de estudo, está formada três meses após a semeadura. A caracterização fenológica, assim como a morfológica, se constitui informação relevante para a identificação da espécie a campo, coleta e análise de sementes, como também, a produção de mudas.Universidade Federal de Santa Maria2013-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/928010.5902/198050989280Ciência Florestal; Vol. 23 No. 2 (2013); 345-353Ciência Florestal; v. 23 n. 2 (2013); 345-3531980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/9280/5441Felippi, MarcieleLonghi, Solon JonasAraujo, Maristela MachadoCaron, Braulioinfo:eu-repo/semantics/openAccess2017-04-17T14:13:57Zoai:ojs.pkp.sfu.ca:article/9280Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T14:13:57Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
