| description | In Brazil, strawberry production is conditioned by the importation of seedlings from different countries, with variable levels of adaptation, different cold requirements and high costs of the introduced material. The national production of seedlings of good genetic, physiological and phytosanitary quality, constitutes a viable alternative for Brazilian producers dedicated to this productive activity. The objective of this work was to evaluate the effect of the application of different concentrations and times of application of calcium prohexadione (ProCa) (growth retardant in various cultivated species), on the magnitude changes of the propagation structures, growth and development of strawberry seedlings cv. Pircinque, the productive behavior and the quality of the fruit. The experiment was carried out in the Agricultural Sciences Center of the Santa Catarina State University (CAV-UDESC) in Lages / SC (Brazil), with a 5 x 2 factorial design, five concentrations of prohexadione calcium (0, 100, 200, 300 and 400 mg L-1) and two periods of aplication (20 and 30 days after the planting of the rooting stolon). In the seedlings, the following were evaluated: number of leaves, crown diameter, height seedling and leaf area. The parameters evaluated in the strawberry plants were: number of fruits per plant, average fruit weight, total fruit weight, dry weight of leaves and crowns, during the cycle 2019/2020. Additionally, firmness, total soluble solids (TSS), titratable. acidity (TA) and ratio were evaluated. The application of ProCa significantly reduces vegetative growth and induces an increase in physiological responses in 'Pircinque' strawberry seedlings, such as leaf area and height for both application periods. On the other hand, ProCa concentrations did not influence the number of fruits and the mass of fruits per plant, nor the quality parameters of the fruit, with the exception of firmness, where it was favored by the concentration of 400 mg L-1. The results were related to the application time factor, where at 20 DAT the highest values of the morphological variables of the seedlings and plants were presented and on the contrary, applications at 30 DAT decrease the number of commercial fruits per plant. |

En Brasil, la producción de fresas está condicionada por la importación de plántulas de diferentes países, con niveles de adaptación variables, diferentes requerimientos de frío y altos costos del material introducido. La producción nacional de plántulas de buena calidad genética, fisiológica y fitosanitaria, se constituye en una alternativa viable para los productores brasileros dedicados a esta actividad. El objetivo de este trabajo fue evaluar el efecto de la aplicación de diferentes concentraciones y épocas de aplicación de prohexadiona de Calcio (Pro-Ca) (retardante del crecimiento en varias especies cultivadas), sobre los cambios de magnitud de las estructuras de propagación, el crecimiento y desarrollo de plántulas, el comportamiento productivo y la calidad del fruto de fresa cv. Pircinque. El experimento se llevó a cabo en el Centro de Ciencias Agrarias de la Universidad Estatal de Santa Catarina (CAV-UDESC) en Lages / SC (Brasil), con un diseño factorial 5 x 2, cinco concentraciones de Prohexadiona de Calcio (0, 100, 200, 300 y 400 mg L-1) y dos períodos de aplicación (20 y 30 días después de transplante del estolón). En las plántulas se evaluó: número de hojas, diámetro de corona, altura de plántula y área foliar. Los parámetros evaluados en las plantas de fresa fueron: número de frutos por planta, peso medio del fruto, peso total de frutos por planta, peso seco de hojas y coronas, durante el ciclo 2019/2020. Además, se evaluó la firmeza, los sólidos solubles totales (TSS), la acidez titulable (AT) y la relación de madurez. La aplicación de Pro-Ca redujo significativamente el crecimiento vegetativo e indujo un aumento de las respuestas fisiológicas en plántulas de fresa cv. 'Pircinque', como el área foliar y la altura para ambas épocas de aplicación. Por otro lado, las concentraciones de Pro-Ca no influyeron en el número de frutos y la masa de frutos por planta, ni en los parámetros de calidad del fruto, con excepción de la firmeza, donde fue favorecida por la concentración de 400 mg L-1. Los resultados se relacionaron con el factor época de aplicación, donde a los 20 DDT se presentaron los valores más altos de las variables morfológicas de las plántulas y plantas; por el contrario, aplicaciones a los 30 DDT disminuyen el número de frutos comerciales por planta.
