Resumo: Given the potential for commercial exploitation of E. spectabile and aiming to curb predatory extractivism, the development of researches that guide its cultivation becomes relevant. This study aims to evaluate the effects of different substrates and seed positions at sowing on the germination and vigor of seeds from two geographical regions. The experiment design was completely randomized in a 2 x 4 x 2 factorial design (seeds from two geographic regions:  i.e., Serra Talhada-PE and Graça-CE, both in Brazil; four substrates: blotting paper, sand, vermiculite and coconut fiber: and two sowing positions: over and in between the substrate). Sowing on blotting paper, sand, vermiculite and coconut fiber, in general, was favorable to germination and germination speed index for seeds from both geographic regions. Sowing in between coconut fiber was detrimental to germination and root development regardless of the seed geographical region. However, sowing in between and over coconut fiber and in between sand favored shoot growth. The best combinations for dry matter production were sowing over paper and sand. The substrates blotting paper, sand, coconut fiber and vermiculite are favorable to E. spectabile seed germination regardless of geographic regions, provided that the sowing is made over the substrates.

En el presente estudio se evaluó el efecto de diferentes sustratos y posiciones de siembra sobre la germinación y el vigor de semillas oriundas de dos regiones geográficas. Se utilizó un diseño completamente aleatorizado, en arreglo factorial 2 x 4 x 2 (semillas de dos regiones geográficas, es decir, Serra Talhada-PE y Graça-CE, ambas en Brasil; cuatro sustratos: papel secante, arena, vermiculita y fibra de coco; y dos posiciones de siembra: sobre y entre el sustrato). La siembra sobre papel secante, arena, vermiculita y fibra de coco, en general, fue favorable a la germinación ya la velocidad de germinación para las semillas de ambas regiones. La siembra en fibra de coco fue perjudicial para la germinación y el desarrollo radicular, independientemente de la región geográfica de las semillas. Sin embargo, la siembra entre y sobre fibra de coco y en arena favoreció el crecimiento de la parte aérea. Las mejores combinaciones para la producción de masa seca fueron la siembra sobre papel y arena. Los sustratos papel secante, arena, fibra de coco y vermiculita son favorables a la germinación de semillas de E. spectabile, independientemente de las regiones geográficas, siempre que la siembra sea sobre los substratos.Dado o potencial de exploração comercial de E. spectabile e visando coibir o extrativismo predatório, torna-se relevante o desenvolvimento de pesquisas que orientem seu cultivo. Este estudo teve como objetivo avaliar o efeito de diferentes substratos e posições da semente na semeadura sobre a germinação e o vigor de sementes de duas regiões geográficas. O delineamento experimental foi inteiramente casualizado em esquema fatorial 2 x 4 x 2 (sementes de duas regiões geográficas: Serra Talhada-PE e Graça-CE, ambas no Brasil; quatro substratos: papel mata-borrão, areia, vermiculita e fibra de coco; e duas posições de semeadura: sobre e entre o substrato). A semeadura em papel mata-borrão, areia, vermiculita e fibra de coco, em geral, foi favorável a germinação e ao índice de velocidade de germinação das sementes das duas regiões geográficas. A semeadura entre a fibra de coco foi prejudicial à germinação e ao desenvolvimento radicular, independentemente da região geográfica das sementes. No entanto, a semeadura entre e sobre a fibra de coco e entre areia favoreceu o crescimento da parte aérea. As melhores combinações para produção de massa seca foram semear sobre papel e areia. Os substratos, papel mata-borrão, areia, fibra de coco e vermiculita são favoráveis à germinação das sementes de E. spectabile, independentemente das regiões geográficas, desde que a semeadura seja feita sobre os substratos.Research, Society and Development2020-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/624510.33448/rsd-v9i8.6245Research, Society and Development; Vol. 9 No. 8; e865986245Research, Society and Development; Vol. 9 Núm. 8; e865986245Research, Society and Development; v. 9 n. 8; e8659862452525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/6245/5956Copyright (c) 2020 Ariana Veras de Araújo, Monalisa Alves Diniz da Silva, André Pereira Freire Ferrazhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAraújo, Ariana Veras deSilva, Monalisa Alves Diniz daFerraz, André Pereira Freire2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/6245Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:27.793311Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
