Resumo: The objective was to determine the treatments and substrates that show the best behavior in relation to the germination of Juglans neotropica seeds. Five physical treatments were used in experiment one and in experiment two three physical treatments and three substrates were combined with completely randomized designs. Germination was monitored daily from 30 days after sowing. The evaluation was related to the germination capacity and the distribution of germination over time, such as: germination percentage, germination vigor, average germination time, speed coefficient, germination speed index and germination uniformity coefficient. The pre-germination treatments with a temperature of 40 and 50 oC in a stove with forced ventilation for two hours and the control, showed significant differences for all the variables, except the coefficient of uniformity, with respect to the scarification treatments with sanding. The highest accumulated germination percentage, 76%, was reached with pre-germination treatments at a temperature of 40 oC in an oven with forced ventilation for two hours. The interaction of substrates with pre-germination treatments do not show significant differences in the germination variables analyzed. Juglans neotropica seeds show asynchronous germination.

Se realizaron dos experimentos: en el primero se utilizaron cinco tratamientos físicos, mientras que en el segundo se combinaron tres tratamientos físicos y tres sustratos, en un diseño completamente al azar. Se monitoreó la germinación de forma diaria, a partir de los 30 días después de la siembra, y se evaluó la capacidad de germinación y la distribución de la germinación en el tiempo, considerando variables como: el porcentaje y vigor de germinación, tiempo promedio de germinación, coeficiente e índice de velocidad de germinación y coeficiente de uniformidad de germinación. Se encontró que los tratamientos de pregerminación con temperaturas de 40 y 50°C en horno con ventilación forzada durante dos horas, así como el testigo, presentaron diferencias significativas en todas las variables evaluadas, excepto en el coeficiente de uniformidad, en comparación con los tratamientos de escarificación con lijado. El mayor porcentaje de germinación acumulada (76%) se obtuvo con los tratamientos pregerminativos a una temperatura de 40°C en estufa con ventilación forzada durante dos horas. La interacción entre los sustratos y los tratamientos pregerminativos no mostró diferencias significativas, en las variables germinativas analizadas. Cabe destacar que las semillas de Juglans neotropica presentan una germinación asincrónica.Universidade Federal de Santa Maria2024-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/8375710.5902/1980509883757Ciência Florestal; Vol. 34 No. 1 (2024): Publicação Contínua; e83757Ciência Florestal; v. 34 n. 1 (2024): Publicação Contínua; e837571980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMspahttps://periodicos.ufsm.br/cienciaflorestal/article/view/83757/63459Copyright (c) 2024 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessCué-García, Jorge LuisRamírez-López, Jorge-LuisChagna Ávila, Eduardo Jaime2024-03-28T13:16:31Zoai:ojs.pkp.sfu.ca:article/83757Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2024-03-28T13:16:31Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
