Resumo: Chromosome counts and meiotic behaviour analysis are excellent contributions  for studies on taxonomic relationships and evolutionary patterns in plants. The tree legume species of the subfamily Caesalpinioideae have been poorly analysed cytogenetically. This work aimed at determining the number of chromosomes and analysing the meiotic behaviour in 11 species of Caesalpinioideae. Basic chromosome numbers in most of the analysed species were 2n = 28 (x = 14). Senna multijuga (L. C. Rich.) H. S. Irwin & Barneby and Schizolobium parahyba (Vell.) Blake presented 2n = 24 (x = 12) and Peltophorum dubium (Spreng.) Taub. 2n = 26 (x = 13). In all the species nuclei presented an areticulate  pattern and a regular meiosis in the six species studied. Further collections and cytogenetic analyses with a major number of individuals and species are suggested, in order  to provide additional data for a more comprehensive study on this group of plants.Leguminosae; chromosome; meiosis.

Espécies de leguminosas arbóreas da subfamília Caesalpinioideae, ocorrentes na Região Sul do Brasil, têm sido pouco analisadas do ponto de vista citotaxonômico. Este trabalho teve por objetivos determinar o número de cromossomos e analisar o comportamento meiótico de onze espécies arbóreas dessa subfamília. O número de cromossomos na maioria das espécies analisadas foi 2n = 28 cromossomos (x = 14). Foi encontrado 2n = 24 (x = 12) em Senna multijuga (L.C. Rich.) H. S. Irwin & Barneby e Schizolobium parahyba (Vell.) Blake, e 2n = 26 (x = 13) em Peltophorum dubium (Spreng.)Taub. Os núcleos apresentaram padrão arreticulado em todas as espécies e o comportamento meiótico foi regular em seis espécies estudadas. Sugere-se ampliação das coletas e análises citogenéticas em mais indivíduos e espécies de forma a gerar informações adicionais que permitam conclusões mais abrangentes sobre este grupo tão importante.Universidade Federal de Santa Maria2005-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/186110.5902/198050981861Ciência Florestal; Vol. 15 No. 3 (2005); 241-248Ciência Florestal; v. 15 n. 3 (2005); 241-2481980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1861/1108Biondo, ElaineMiotto, Sílvia Teresinha SffoggiaSchifino-Wittmann, Maria Teresainfo:eu-repo/semantics/openAccess2017-05-15T19:04:56Zoai:ojs.pkp.sfu.ca:article/1861Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T19:04:56Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
