Resumo: | Quesnelia quesneliana is an endemic species from Brazil with restricted distribution in restinga areas and has been suffering from changes in its habitat. This study aimed to evaluate the influence of light on the morpho-anatomy and pigment content of Q. quesneliana. The samples were collected in the Liberdade neighborhood in São Mateus, Espírito Santo State, Brazil, which is impacted by anthropization. The influence of light was tested comparing individuals completely exposed to it and individuals under shade. For a morphobiometric analysis, 150 individuals were measured for each light condition, and for pigment determination, 10 leaves were used for each light condition. For anatomical analysis, samples were fixed in 50% FAA and transferred to 70 % ethanol solution after 48 hours. Cross sections were made on roots and stems, and transverse and paradermal sections on leaves. It was concluded that individuals exposed to light are smaller, with higher carotenoid content, while shaded individuals are larger, with more succulent and darker leaves due to greater accumulation of chlorophyll. Anatomically, the individual’s structure is similar. |

O trabalho objetivou avaliar a influência da luminosidade na morfoanatomia e conteúdo de pigmentos foliares de Q. quesneliana. As amostras foram coletadas no bairro Liberdade em São Mateus, Estado do Espírito Santo, Brasil, que sofre com ações antrópicas. A influência das condições de luminosidade foi testada comparando indivíduos completamente expostos à luminosidade e à sombra. Para as análises morfobiométricas foram mensurados 150 indivíduos por condição luminosa, e para a determinação de pigmentos, foram utilizadas 10 folhas por condição luminosa. Para a análise anatômica, as amostras foram armazenadas em FAA 50 para fixação e transferidas para etanol 50% após 48 horas. Foram realizadas secções transversais em raízes e caules, e secções transversais e paradérmicas em folhas. Conclui-se que os indivíduos expostos a luminosidade são menores, com maior teor de carotenoides, enquanto os indivíduos sombreados são maiores, com folhas mais suculentas e escuras devido ao maior acúmulo de clorofila. Anatomicamente, a estrutura dos indivíduos é similar.SciELO PreprintsSciELO PreprintsSciELO Preprints2022-04-01info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/383310.1590/2236-8906-62/2020-Aporhttps://preprints.scielo.org/index.php/scielo/article/view/3833/7242Copyright (c) 2022 Letícia Elias, Patrícia Denoni de Lima, Gabriela de Souza Fontes, Elisa Mitsuko Aoyamahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessElias, LetíciaLima, Patrícia Denoni deFontes, Gabriela de SouzaAoyama, Elisa Mitsukoreponame:SciELO Preprintsinstname:SciELOinstacron:SCI2022-03-25T21:30:23Zoai:ops.preprints.scielo.org:preprint/3833Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2022-03-25T21:30:23SciELO Preprints - SciELOfalse |
