Resumo: | The study, conducted at São Francisco National Forest, in Rio Grande do Sul, had as objectives to quantify the number of female and male Araucaria angustifolia individuals, as well as to study the diametric distribution in a 25.11 ha of a 60 years old forest. The sex classification was done in the periods of floral components maturation, and the dendrometric survey was done in order to obtain the diameter and the frequency upon the total sampling area. There was no significative difference in average diameter, being 42 cm for female individuals and 38.5 cm for male individuals. The relative proportion of female individuals was of 43.65 % and 56.35 % for male individuals; 65.3 % of the trees were concentrated between the diametric classes of 35-45 cm. The diametric distribution followed the normal distribution, having a higher presence of female individuals in higher diametric classes and higher amounts of male individuals in lower classes. |

O estudo realizado na Floresta Nacional de São Francisco de Paula, Rio Grande do Sul, teve como objetivos quantificar o número de indivíduos femininos e masculinos, de Araucaria angustifolia, bem como estudar a distribuição diamétrica, em floresta de 25,11 ha, com 60 anos de idade. A classificação por sexo foi realizada nos períodos de maturação dos componentes florais e o levantamento dendrométrico efetuado para obtenção do diâmetro e frequência, sobre toda a área amostral. A proporção relativa de indivíduos do sexo feminino foi de 43,65% e de 56,35% para o masculino; 65,3% das árvores estavam concentradas entre as classes de diâmetro de 35-45 cm. Não houve diferença significativa em diâmetro médio, sendo encontrado para o sexo feminino 42 cm e para o masculino 38,5 cm. A distribuição diamétrica obedeceu à distribuição normal, sendo que houve presença de maior número de indivíduos do sexo feminino nas maiores classes diamétricas e maiores quantidades de indivíduos masculinos nas menores classes.Universidade Federal de Santa Maria2009-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/89710.5902/19805098897Ciência Florestal; Vol. 19 No. 4 (2009); 425-431Ciência Florestal; v. 19 n. 4 (2009); 425-4311980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/897/625Zanon, Magda Lea BolzanFinger, César Augusto GuimarãesSchneider, Paulo Renatoinfo:eu-repo/semantics/openAccess2017-05-08T13:04:41Zoai:ojs.pkp.sfu.ca:article/897Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-08T13:04:41Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
