Resumo: The number of chromosomes and the meiotic characterization are important to studies involving genetic variability, germplasm and biodiversity. However, native forest species have not been sufficiently analyzed from a cytotaxonomic point of view. Therefore, the number of chromosomes, the meiotic behavior and the pollen viability of the Diatenopteryx sorbifolia Radlk were determined from five different accessions located in the southern region of Brazil. The species was considered diploid, 2n = 30 (x = 15), with regular meiotic behavior in phase I and absent in phase II, suggesting the presence of a genetic abnormality. Pollen grains infertility was between 57 and 67%. which may be associated to the formation of a low number of seeds in Diatenopteryx sorbifolia, probably due to the irregular behavior of the microsporogenesis.

Entretanto, espécies florestais nativas não são suficientemente analisadas do ponto de vista citotaxonômico. Dessa forma, o número de cromossomos, o comportamento meiótico e a viabilidade polínica de Diatenopteryx sorbifolia Radlk foram determinados a partir de cinco acessos diferentes localizados na região sul do Brasil. A espécie foi considerada diplóide, 2n = 30 (x = 15), com comportamento meiótico regular na fase I e ausente na fase II, sugerindo a presença de uma anormalidade genética. A infertilidade dos grãos de pólen ficou entre 57 e 67%, o que pode estar associado à formação de um baixo número de sementes em Diatenopteryx sorbifolia, provavelmente em decorrência do comportamento irregular na microsporogênese.Universidade Federal de Santa Maria2022-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoinfo:eu-repo/semantics/otherapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4807210.5902/1980509848072Ciência Florestal; Vol. 32 No. 1 (2022); 233-246Ciência Florestal; v. 32 n. 1 (2022); 233-2461980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/48072/47518https://periodicos.ufsm.br/cienciaflorestal/article/view/48072/50573Copyright (c) 2022 Ciência Florestalhttps://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccessFilippi, MarcieleBoldrini, Kellen ReginaAgostinho, Karoline FontanaCorrêa, Bruno Jan SchrammDonazzolo, Joel2023-03-10T15:26:09Zoai:ojs.pkp.sfu.ca:article/48072Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-03-10T15:26:09Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
