Resumo: Juçara (Euterpe edulis Martius) is a palm species from the Atlantic Forest whose fruits are important as a source of food to several individuals from the fauna of the region. Despite its ecological importance, juçara is found in the list of endangered species, due to the fragmentation of the forests and the illegal extraction of the heart of palm. We aimed to evaluate the inter- and intra-populational genetic diversity of E. edulis based on fruit and seed traits in forest fragments of the Espírito Santo State in Brazil.  The aim was to generate information to be used in E. edulis breeding programs, or in the delineation of more efficient management and reforestation strategies. The study was carried out in 20 forest fragments and 198 fruit plants were sampled. Positive genetic association was observed between the evaluated traits, with the longitudinal diameter of the fruit (LDF) and the seed mass (SM) greatly affecting fruit mass (FM). The existence of inter- and intra-populational genetic divergence was proved. The genetic divergence found in E. edulis suggests that there is genetic material that can be explored in breeding programs and this information may also contribute to management strategies that can increase the species genetic diversity.

Apesar de sua importância ecológica, juçara é encontrada na lista de espécies ameaçadas à extinção, devido à fragmentação florestal e à extração ilegal do palmito. Nós tivemos como objetivo avaliar a diversidade genética inter e intra populacional de E. edulis com base em caracteres de frutos e sementes, em fragmentos florestais do Estado do Espírito Santo no Brasil, com o objetivo de gerar informações a serem utilizadas nos programas de melhoramento de E. edulis ou na delimitação de estratégias de manejo e reflorestamento mais eficientes. O estudo foi realizado em 20 fragmentos florestais e 198 plantas frutíferas foram amostradas. Foi observada uma grande associação genética positiva entre os caracteres avaliados, com as características diâmetro longitudinal dos frutos (LDF) e massa de sementes (SM) apresentando efeitos maiores do que a massa característica da fruta (FM). A existência de divergência genética inter e intrapopulacional foi comprovada. A divergência genética encontrada neste trabalho para E. edulis sugere a presença de material genético que vale a pena ser explorado em programas de melhoramento e essa informação também pode contribuir com estratégias de manejo para aumentar a diversidade genética das espécies.EDUFU2020-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4195410.14393/BJ-v36n5a2020-41954Bioscience Journal ; Vol. 36 No. 5 (2020): Sept./Oct.; 1549-1556Bioscience Journal ; v. 36 n. 5 (2020): Sept./Oct.; 1549-15561981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/41954/29609Brazil; ContemporaryCopyright (c) 2020 Tiago de Souza Marçal, Carolina de Oliveira Bernardes, Wagner Bastos dos Santos Oliveira, José Henrique Soler Guilhen, Marcia Flores da Silva Ferreira, Adésio Ferreirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMarçal, Tiago de SouzaBernardes, Carolina de OliveiraOliveira, Wagner Bastos dos SantosGuilhen, José Henrique SolerFerreira, Marcia Flores da SilvaFerreira, Adésio2022-06-10T13:29:07Zoai:ojs.www.seer.ufu.br:article/41954Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-10T13:29:07Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
