Zusammenfassung:Background. The use of liquid algae extract as a biostimulant when applied to leaves or roots, improves crop development and consequently yield, since by stimulating natural processes they benefit from the use of nutrients and increases resistance to conditions of biotic and / or abiotic stress. Objective. This investigation evaluated the response of two varieties of Eustoma grandiflorum to foliar and root application of algae extracts, grown in pots under nursery conditions. Methodology. Macroalgae extract was applied in a foliar way (20 mL spray) and directly to the substrate (50 mL), while drinking water was applied as the control. Results. The parameters obtained indicate that the foliar application has noticeably effects on var. Rosie for the variables root length, number of shoots, and number of leaves; while for var. Florida, the variables total plant length and number of shoots obtained greater significance. The method of application via substrate generates positive effects on the total length and stem length for var. Rosie, although the variables with the greatest noticeably were obtained from var. Florida for root length, number of leaves, and flower diameter. Implications. The low doses of the algae extracts, application form and the handling of cultural tasks during the growth of E. grandiflorum, contribute to a better absorption and/or efficiency of the fertilizers in the crop. Conclusion. The application of algae extracts favors the production of E. grandiflorum under nursery conditions, making their use a viable option to minimize the application of conventional fertilizers, thereby attenuating the effects on the environment.EFECTO DEL EXTRACTO LÍQUIDO DE ALGAS MARINAS EN EL CRECIMIENTO EN MACETA DE Eustoma grandiflorum (Raf.) Shinners).Antecedentes. El uso de extracto liquido de algas como bioestimulante cuando se aplican a las hojas o en las raices, mejora el desarrollo del cultivo y consecuentemente el rendimiento, ya que mediante la estimulación de procesos naturales benefician el aprovechamiento de nutrientes e incrementa la resistencia a condiciones de estrés biótico y/o abiótico. Objetivo. Esta investigación evaluó la respuesta de dos variedades de Eustoma grandiflorum a la aplicación foliar y radicular de extractos de algas, cultivadas en macetas en condiciones de vivero. Metodologia. El extracto de macroalgas se aplicó de forma foliar (20 mL) y directamente al sustrato (50 mL), mientras que el agua potable se aplicó como control. Re
