Resumo: We aimed to evaluate the regenerative potential of the tree component in an ecotonal area between Araucaria and Deciduous forests, in the Upper Uruguay region, Santa Catarina state. For this, a floristic-structural description of the regenerative component was conducted for different size classes and the floristic similarity among classes and adult component was verified. Three classes were considered for the regenerative component: Class 1, plants from 0.2 up to 1 m high, Class 2, plants greater than 1 m up to 3 m high, and Class 3, plants greater than 3 m high, with cbh < 5.0 cm. Information about the adult component for the same sampling units were extract from the database of the Dendrology and Phytosociology Laboratory (LABDENRO), of Santa Catarina State University. All the regenerative species were classified into regeneration guilds (pioneers, light demanding climax, shade tolerant climax), based on literature review and on field observations. For the whole component and for each size class, the Shannon diversity (H’) and Pielou Eveness (J) indexes, and the Class (RNC) and Total (RNT) Natural Regeneration Indexes were determined. The floristic similarities between components were obtained by Sorensen Index. A chi-square applied to a contingency table was conducted to verify the existence of association between the distribution of individuals belonging to different regeneration guilds and size classes. A total of 771 regenerative individuals were sampled, belonging to 52 species, whose H’ and J were, respectively, 3.06 and 0.77. The species with the greatest RNT was Nectandra megapotamica (Spreng.) Mez. The similarity with the adult component varied between 0.46 for Class 3 and 0.62 for Class 1. In all size classes, there was the predominance of individuals of climax light demanding species. We conclude that the adult species component was mostly represented within the smaller plant size class, where the largest proportion of sampled individuals was found.

Para isso, foi realizada a caracterização florístico-estrutural do componente arbóreo regenerante em diferentes classes de tamanho e verificada a similaridade florística entre as classes e o componente adulto. Foram consideradas três classes para o componente regenerante: Classe 1, plantas com altura entre 0,2 e 1 m, Classe 2, plantas maiores que 1 m e até 3 m, e Classe 3, plantas maiores que 3 m e com DAP < 5,0 cm. Informações sobre o componente adulto para as mesmas unidades amostrais foram extraídas do banco de dados Laboratório de Dendrologia e Fitossociologia (LABDENDRO), da Universidade do Estado de Santa Catarina. Todas as espécies regenerantes foram classificadas em guildas de regeneração (pioneiras, climácicas exigentes em luz e climácicas tolerantes à sombra), a partir de revisão de literatura e observações de campo. Para todo o componente e para cada classe de tamanho, foram calculados os índices de diversidade de Shannon (H’), de equabilidade de Pielou (J) e os Índices de Regeneração Natural por Classe (RNC) e Total (RNT). As similaridades entre os componentes foram obtidas pelo Índice de Sorensen. Foi realizado um teste de qui-quadrado aplicado a uma tabela de contingência para verificar a existência de associação entre a distribuição dos indivíduos pertencentes a espécies de diferentes guildas de regeneração e a classe de tamanho. Foram amostrados 771 indivíduos regenerantes, distribuídos em 51 espécies, cujos valores de H’ e J foram, respectivamente, de 3,06 e 0,77. A espécie com maior RNT foi Nectandra megapotamica (Spreng.) Mez. A similaridade com o componente adulto variou entre 0,46 para a Classe 3 e 0,62 para a Classe 1. Em todas as classes de tamanho ocorreu a predominância de indivíduos de espécies classificadas como clímax exigentes em luz. Conclui-se que as espécies do componente adulto estão representadas, principalmente, na classe de menor tamanho, na qual se encontra a maior parte dos indivíduos amostrados.Universidade Federal de Santa Maria2018-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3160510.5902/1980509831605Ciência Florestal; Vol. 28 No. 1 (2018); 345-356Ciência Florestal; v. 28 n. 1 (2018); 345-3561980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/31605/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessSouza, Chayane Cristina deRosa, Angélica DallaSouza, KarineCruz, Aline PereiraGonçalves, Didiane AnaPscheidt, FrancieliLoebens, RodineliHiguchi, PedroSilva, Ana Carolina2018-04-23T20:26:11Zoai:ojs.pkp.sfu.ca:article/31605Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-04-23T20:26:11Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
