Resumo: The biostimulating potential of algae extracts represents an opportunity to increase efficiency in food production. Cultivable microalgae are viable candidates due to the high production capacity. In this work, the chemical composition and effect of the microalgae extract Scenedesmus acuminatus (Lagerh.) Chodat and commercial product AMPEP (Acadian Marine Plant Extract Powder) derived from the macroalgae Ascophyllum nodosum (L.) Le Jol. on the germination of BRS Estilo bean seeds were evaluated. The treatments analyzed the methodology of exposure of seeds to extracts: soaking for 5 hours (T1) and applications every 48 hours (T2). The parameters evaluated were: germination percentage (PG), speed index (IVG) and mean germination time (TMG). The values of PG and IVG were higher in T2, representing about 50% higher yield than T1. In relation to chemical composition, Scenedesmus acuminatus extract obtained higher levels of proteins and carbohydrates. Thus, S. acuminatus is a potential producer of biostimulant extracts, while beans obtained lower germinative performance when submitted to the soaking process.

As microalgas cultiváveis são candidatas viáveis em função da elevada capacidade de produção. Neste trabalho foi avaliada a composição química e efeito do extrato de microalga Scenedesmus acuminatus (Lagerh.) Chodat e produto comercial AMPEP (Acadian Marine Plant Extract Powder) derivado da macroalga Ascophyllum nodosum (L.) Le Jol. na germinação de sementes de feijão BRS Estilo. Os tratamentos analisaram a metodologia de exposição das sementes aos extratos: embebição por 5 horas (T1) e aplicações a cada 48 horas (T2). Os parâmetros avaliados foram: porcentagem de germinação (PG), índice de velocidade (IVG) e tempo médio de germinação (TMG). Os valores de PG e IVG foram superiores no T2, representando cerca de 50% de rendimento maior que o T1. Em relação a composição química, o extrato de Scenedesmus acuminatus obteve maiores teores de proteínas e carboidratos. Dessa forma, S. acuminatus é potencial produtora de extratos bioestimulantes, enquanto feijão obteve menor desempenho germinativo quando submetido ao processo de embebição.SciELO PreprintsSciELO PreprintsSciELO Preprints2021-06-07info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/243710.1590/2236-8906-100/2020porhttps://preprints.scielo.org/index.php/scielo/article/view/2437/4144Copyright (c) 2021 Nair Hildelgard Soares dos Santos, Ana Clara Duarte Silveira, Valéria de Oliveira Fernandes, Levi Pompermayer Machadohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Nair Hildelgard Soares dos Silveira, Ana Clara Duarte Fernandes, Valéria de Oliveira Machado, Levi Pompermayer reponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-06-03T02:25:44Zoai:ops.preprints.scielo.org:preprint/2437Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-06-03T02:25:44SciELO Preprints - SciELOfalse
