Efecto de pretratamientos en semillas de Enterolobium contortisiliquum (Fabaceae) de la selva pedemontana argentina

Abstract: Summary:The effect of pretreatments in Enterolobium contortisiliquum seeds (Fabaceae) from Selva Pedemontana of Argentina. Enterolobium contortisiliquum (Vell.) Morong is a tree species that lives in the Selva Pedemontana of Argentina, that is extensively exploited for ample crop. Its seeds typically exhibit low germination percentage due to the high level of dormancy. Five different methods to overcome dormancy were evaluated on seeds collected for five populations along a latitudinal and altitudinal gradient… Show more

“…Enterolobium contortisiliquum (Vell.) Morong germinated with immersion in sulfuric acid for 30 to 50 min without significant difference between immersion/soaking periods (Lozano et al, 2016). Gledistchia amorphoides Taub seeds subjected to chemical scarification for 1 or 2 h had germination increased by 70% and anticipated in 15 days (Bortolini et al, 2011).…”

“…These results were higher than those found by Scalon et al (2005) when immersion in sulphuric acid for 10 min was used and Alexandre et al (2009) when mechanical scarification was applied, which obtained 83 and 80% germination rates respectively. However, Lozano et al (2016) used the mechanical scarification and chemical scarification with sulphuric acid method for 30 to 50 min to obtain 100% germination rates of seeds of the Enterolobium contortisiliquum collected in Choromoro in Argentina. Among the factors that might have contributed to the higher germination rate in this study were the longer immersion time in sulphuric acid as well as environmental factors.…”

“…El Enterolobium ciclocarpum, denominado popularmente orejero, crece en zonas tropicales y subtropicales secas, pertenece a la familia Fabaceae (mimosaceae), es un árbol de gran altura con copa globosa, sus hojas son verdes y bipinadas, las flores son actinomórficas, con corola verde clara, cáliz verde y tubular; sus semillas son de color marrón, grandes (2.3 por 1.5 cm), ovoides y aplanadas, se encuentran dentro de vainas circulares indehiscentes, con forma arriñonada similar a una oreja de allí su nombre común, caen abundantemente del árbol las cuales son ingeridas por bovinos y equinos, (Martínez et al, 2012). Las investigaciones están orientadas a la floración y fructificación (Pineda et al, 2017), la evaluación del desarrollo del árbol en condiciones controladas (Hernández et al, 2014) y promover la germinación (Lozano et al, 2016). Las especies Thevetia peruviana, Gossypium hirsutum L y Enterolobium ciclocarpum, abundan en el departamento de Córdoba, y su utilidad es limitada; de acuerdo con la literatura consultada se encuentran muy pocos estudios sobre el aceite y la torta de estas materias primas, es por ello que el objetivo de este artículo estuvo encaminado a analizar las propiedades fisicoquímicas del aceite, su perfil de ácidos grasos y el contenido nutricional o análisis proximal de la torta de las tres semillas oleaginosas, con el fin de encontrar una posible aplicabilidad en la industria, para contribuir con el desarrollo de la región y del país.…”
