Objective: Plant life begins at germination. Stimulating germination with chemical methods can be advantageous. The pregerminative treatment of four promoters was determined in two maize genotypes (G1, G2). Design/methodology/approach: Sixty seeds per Petri dish were used as experimental unit with three repetitions, organized in a completely randomized 2×4 factorial design. Two factors were taken into consideration: A) Genotypes (G1, G2); and B) four pregerminative promoters. The genotypes were Antelope G1 and yellow Antelope G2. Meanwhile, the pregerminative promoters were salicylic acid (C7H6O3) (SA), citrulline (C6H13N3O3) (CI), humic substances derived from leonardite (HS), and tap water (TW), in 1000-ppm concentrations. The following variables were evaluated: germination percentage (GP)/days-1, radicle diameter (RD), radicle length (RL), and number of lateral seminal roots (NSR). An analysis of variance and Tukey tests (α £ 0.05) were performed. Results: The germination promoters were highly significant in both genotypes, as well as during the promoter-genotype interaction. G1 and G2 means showed a higher growth and development for humic substances (HS) during germination in the NSR. Study Limitations/Implications: Germination can be inhibited, if the promoters are overweighted. Findings/Conclusions: The best genotype and germination promoter (G2) had a 94% effectiveness and HS at 1000 ppm. CI and SA registered the lowest GP.
Por la importancia que tienen los minerales en la nutrición se evaluó la acumulación de cobre (Cu) en el forraje verde hidropónico de trigo (FVH) en diferentes soluciones y modificaciones en el pH. Se utilizó un arreglo factorial completamente al azar de 3 x 4 x 3 con tres repeticiones. Cada charola representó una unidad experimental, los factores de estudio fueron tres diferentes soluciones, cuatro tratamientos de cobre y tres niveles de pH; factor A, agua de la llave (ALl), solución nutritiva (SN) (método de Steiner) con agua destilada (AD) y solución nutritiva (SN) con agua de llave (ALl); factor B, productos de Cu (4, 1.3, 0.28 y 25%) y factor C pH (5.0, 6.0 y 7.8). Las variables evaluadas fueron: contenido de cobre y análisis bromatológicos. Los resultados fueron sometidos a un análisis de varianza y se realizaron las separaciones de medias mediante la prueba de Tukey (α ± 0.05. Existió una mayor absorción de cobre en la interacción de Agua de llave (ALl) con respecto al fertilizante (F) en concentración de 1.30% Cu-EDTA presentando una concentración de 5.51 ppm, y en las soluciones de agua destilada (AD) con solución nutritiva (SN) y pH 6 mostrando una absorción de 3.94 ppm. El contenido de cobre en el forraje modifico FDA y FDN, estos resultados pueden ser de utilidad en estudios futuros para realizar más ensayos sobre los caracteres bioquímicos relacionados con la digestibilidad del forraje, y en la biofortificación.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
