CAMARGO, Letícia KP et al. Postharvest quality of strawberry fruits produced in organic and conventional systems. Hortic. Bras. [online]. 2011, vol.29, n.4, pp. 577-583. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362011000400022.

The aim of this study was to determine some physicochemical characteristics of fruits of eight strawberry cultivars (Aromas, Camino Real, Campinas, Dover, Oso Grande, Toyonoka, Tudla-Milsei and Ventana) cultivated in organic and conventional systems. The evaluated characteristics were soluble solids (SS), titratable acidity (TA), SS/AT ratio and anthocyanins. Evaluated sensory characteristics were flavor and appearance. The cultivars had a differential performance between themselves and among the systems for the evaluated characteristics. Generally, the conventional system produced fruit with higher levels of soluble solids and, organic system produced higher concentrations of anthocyanins. The fruits of the cultivar Toyonoka had the best soluble solids content in both systems and the anthocyanins content of 'Tudla-Milsei' and 'Camino Real' were proeminent in comparison to the other cultivars. The fruits from the organic system of production were preferred by judges on the sensorial attributes. The highest notes were given to the appearance of the cultivar Ventana in the conventional system and 'Tudla-Milsei' in the organic system.
