Resumo: The objective of this study is to determine ploidy of aspérmico cupuaçuzeiro. The counting of chromosomes was carried out in the subapical meristem cells from the ends of the branches, because this tissue has large cells that allow better spreading of the chromosomes and facilitate counting. The cupuaçu is a natural seedless triploid with 30 chromosomes. The chloroplasts and size of guard cells and the thickness of the sheets is in accordance with the state of cupuaçuzeiro of triploid seedless fruits. This suggests that natural triploidy new aspérmicos triploids can be obtained from crosses between diploid and tetraploid induced by colchicine, whose presumed advantages are discussed.

A contagem dos cromossomos foi realizada em células do meristema subapical das extremidades dos ramos, porque esse tecido possui células grandes, que permitem melhor espalhamento dos cromossomos e facilitam a contagem. O cupuacuzeiro sem sementes é um triplóide natural, com 30 cromossomos. O cloroplastos e o tamanho das celulas-guarda, bem como a espessura das folhas, está de acordo com o estado triplóide do cupuacuzeiro de frutos sem sementes. Essa triploidía natural sugere que novos triplóides aspérmicos podem ser obtidos de cruzamentos entre diplóides e tetraplóides induzidos por colchicina, cujas vantagens presumíveis são discutidas.Universidade Federal Rural da Amazônia/UFRA2011-05-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/271Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 46 No 1 (2006): RCA; 143 - 150Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 46 n. 1 (2006): RCA; 143 - 1502177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
