Resumen/Descripción – provisto por el repositorio digital
About 8.000.000 tons of strawberry (Fragaria ananassa Duch.) are produced globally and 50000 t in Argentina in about 1300 hectares. The productive varies between the first and second year, for which ecophysiological, productive and environmental aspects, were evaluated in this work in variety Aromas and in the Horticultural Belt of the City of Mar del Plata-Miramar (38º16 'S, 57º50' W, 29 m). Treatments: one and two years old plants, planted in 2009 and one year old plants, planted in 2010. The two years old plants surpassed to one year old plants in: total biomass and partition to the fruits, having the highest growth rate in spring meanwhile the first year old plants in summer. At the beginning of growth season the roots and crowns of the two years plants were 14 and 24 times heavier than the one year plants, and exceeding them in 12 crowns per plant. In one year old plants the crop growth rate and fruit growth rate were strongly correlated with the average temperature, which below 15 °C reduced the fruit growth rate in all the treatments. The crop growth rate and evolution of leaf area index was correlated with radiation. Fruit production was significantly higher in two year-old plants, although fruit size was 25% lower, which would be explained by the higher target: source ratio. The variations in production appear to be more related to endogenous factors than the temperature influence.Palabras clave – provistas por el repositorio digital
