Esta investigación evaluó los efectos fitotóxicos del cadmio en el desarrollo germinativo y el crecimiento inicial de Gossypium hirsutum L. Se evaluaron los efectos ecotoxicológicos de 13 concentraciones experimentales de cadmio (0.0-50.0 mM) sobre variables de respuesta como porcentaje de germinación (IVG), tiempo promedio de germinación (TMG) y longitud de la raíz de las plántulas. Las semillas de G. hirsutum expuestas al cadmio mostraron una disminución en el porcentaje de germinación y un aumento en el número de plántulas anormales con las concentraciones 18.0 y 3.0 mM, respectivamente, además de inhibir el crecimiento de la raíz y elevar el TMG de la exposición a 0,5 mM, reduciendo el IVG. G. hirsutum es una especie tolerante al cadmio durante su desarrollo germinativo This research evaluated the phytotoxic effects of cadmium on the germination development and initial growth of Gossypium hirsutum L. The ecotoxicological effects of 13 experimental concentrations of cadmium (0.0-50.0 mM) on variables like germination percentage, GSI, average germination time (AGT) and root length were evaluated. G. hirsutum seeds exposed to cadmium showed a decrease in germination percentage and an increase in the number of normal plantules from the concentrations 18.0 and 3.0 mM, respectively. It also inhibited root growth and increased the AGT from the exposure to the concentration 0.5 mM, reducing the GSI. G. hirsutum is tolerant to cadmium during its germinal stage.
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.
