Resumo: Pollen fertility is indicated by viability, which influences the reproductive success of plants. Mandacaru is a native tree species with natural distribution in the Caatinga. The objective was to verify the pollen viability, pollen per ovule ratio and the morphological identification of the mandacaru flower (Cereus jamacaru). Ten flower buds were used and one hundred anthers of these buds, which and stained with Alexander dye on checkered glass slide and viable and non-viable pollens were accounted amount of ovule per flower bud was counted the pollen/ovule ratio. Mandacaru presented viability of 99.41% the pollen, with an average of 314,686 pollens on each flower. There were 356 pollens for each ovule, this indicates the species reproductive system for facultative autogamous and facultative xenogamics. The flower is hermaphrodite, with gynoecium measuring an average of 160.9 mm, an average of 883 ovules per flower, the androecium averaging 577 anthers per flower, 545 pollen per anther. Mandacaru has high pollen viability, with large size hermaphrodite flower, with high number of anthers and pollen contained in these anthers.

Mandacaru es una especie nativa de tamaño arbóreo, con distribución natural en el bioma Caatinga. El objetivo era verificar la viabilidad del polen, la relación polen-huevo y la identificación morfológica de la flor de mandacaru (Cereus jamacaru). Se utilizaron diez yemas florales para la viabilidad del polen y cien anteras de estas yemas, que se tiñeron con tinte Alexander en un portaobjetos de vidrio y se contaron pólenes viables y no viables, se contó el número de huevos por flor y relación polen / huevo. Mandacaru mostró una viabilidad de polen de 99.41%, con un promedio de 314,686 pólenes en cada flor. Había 356 pólenes por cada huevo, lo que indica el sistema reproductivo de la especie para el autogamo facultativo y el xenogamo facultativo. La flor es hermafrodita, con ginecium midiendo un promedio de 160.9 mm, con un promedio de 883 huevos por flor, el androceu mostró un promedio de 577 anteras por flor y 545 granos de polen por antera. Mandacaru tiene una alta viabilidad de polen, con una flor hermafrodita de gran tamaño, con una gran cantidad de anteras y granos de polen contenidos en estas anteras.A fertilidade do pólen é indicada pela viabilidade, a qual tem influência sobre o sucesso reprodutivo de plantas. O mandacaru é uma espécie nativa de porte arbóreo, com distribuição natural na Caatinga. Objetivou-se verificar a viabilidade do pólen, razão pólen-óvulo e a identificação morfológica da flor do mandacaru (Cereus jamacaru). Foram utilizados dez botões florais e cem anteras destes botões, as quais foram coradas com corante Alexander em lâmina de vidro e contabilizou-se os pólens viáveis e inviáveis, foram contabilizados a quantidade de óvulos por botão floral e verificou-se a razão pólen/óvulo. O mandacaru apresentou viabilidade polínica de 99,41%, com média de 314.686 pólens em cada flor. Foram 356 pólens para cada óvulo, que indica o sistema reprodutivo da espécie para autógama facultativa e xenogâmica facultativa. A flor é hermafrodita, com gineceu medindo em média 160,9 mm, com média de 883 óvulos por flor, o androceu apresentou média de 577 anteras por flor, e 545 grãos de pólens por antera. O Mandacaru apresenta pólen com alta viabilidade, com flor hermafrodita, de tamanho grande, com quantidade elevada de anteras e grãos de pólens contidos nestas anteras.Research, Society and Development2020-08-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/667110.33448/rsd-v9i8.6671Research, Society and Development; Vol. 9 No. 8; e997986671Research, Society and Development; Vol. 9 Núm. 8; e997986671Research, Society and Development; v. 9 n. 8; e9979866712525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/6671/6110Copyright (c) 2020 Paulo Marks de Araújo Costa, Vênia Camelo de Souza, Ivan Sérgio da Silva Oliveira, Vagner Sousa da Costa, Emerson Serafim Barroshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Paulo Marks de AraújoSouza, Vênia Camelo de Oliveira, Ivan Sérgio da SilvaCosta, Vagner Sousa da Barros, Emerson Serafim2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/6671Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:42.813498Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
