Resumo: | The objective of this work was to evaluate the viability of the micrografting of yellow dragon fruit (Selenicereus megalanthus) on different rootstocks, based on DNA content and anatomical analyses. The used rootstocks were: yellow dragon fruit, white dragon fruit (Hylocereus undatus), Saborosa (Selenicereus setaceus) dragon fruit, and the Cebra and Orejona red dragon fruit (Hylocereus polyrhizus) varieties. The experimental design was completely randomized with five treatments and four replicates of five plants. After 30 days of cultivation, the following traits were evaluated: length and diameter of the micrografts and microrootstocks; and root length, percentage of setting, and fresh mass of the micrografts. Flow cytometry analyzes were performed before and after micrografting to verify genetic stability and the occurrence of endoreduplication. In addition, histological sections were made in the micrografting region to verify the connections of vessels and tissues between the graft and the rootstock. Endoreduplication was observed in all treatments. The amount of DNA in the yellow dragon fruit micrograft increased on the red Orejona variety. The presence of vessel connections was verified between the micrografts and microrootstocks. The yellow dragon fruit was also more vigorous when grafted on Orejona. Based on DNA content and anatomical analyses, in vitro yellow dragon fruit micrografting is feasible in all used rootstocks. |

Os porta-enxertos utilizados foram: pitaia amarela, pitaia branca (Hylocereus undatus), pitaia Saborosa (Selenicereus setaceus), e as variedades Cebra e Orejona de pitaia vermelha (Hylocereus polyrhizus). O delineamento experimental foi inteiramente casualizado, com cinco tratamentos e quatro repetições de cinco plantas. Após 30 dias de cultivo, avaliaram-se as seguintes características: comprimento e diâmetro dos microenxertos e dos microporta-enxertos; e comprimento de raízes, percentagem de pegamento e massa fresca dos microenxertos. Realizaram-se análises de citometria de fluxo antes e depois da microenxertia, para verificação da estabilidade genética e da ocorrência de endoreduplicação. Além disso, foram feitos cortes histológicos na região da microenxertia, para verificação das conexões dos vasos e dos tecidos entre o enxerto e o porta-enxerto. Observou-se endoreduplicação em todos os tratamentos. A quantidade de DNA do microenxerto de pitaia amarela aumentou sobre a variedade vermelha Orejona. Verificou-se a presença de conexões de vasos entre os microenxertos e os microporta-enxertos. A pitaia amarela também foi mais vigorosa quando enxertada sobre Orejona. Com base nas análises de conteúdo de DNA e anatômicas, a microenxertia de pitaia amarela in vitro é viável em todos os porta-enxertos utilizados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e TecnológicoConselho Nacional de Desenvolvimento Científico e TecnológicoMoreira, Renata AmatoRodrigues, Mariane AparecidaMagalhães, Deniete SoaresPio, Leila Aparecida SallesSantos, Dalilhia Nazaré dosGuimarães, Paulo Henrique SalesRamos, José DarlanPascoal, Moacir2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26998Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e01867Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e018671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26998/14943Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26998Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
