Qualidade pós-colheita de frutos de tomateiro submetidos a preparados em altas diluições

Abstract

Tomato fruits are sensitive to handling and its quality is determined by the crop system and the post-harvest conservation practices. The aim of this work was to evaluate the influence of high dilution preparations in the post-harvest attributes of tomato fruits. The research consisted of one field experiment in the 2009/2010 crop cycle and laboratory assay in post-harvest. The high dilution preparations studied under field conditions were nosodes of tomato plant and Solanum aculeatissimum at 12 and 24DH (decimal hahnemanian dilutions) and the homeopathies Arnica montana and Sulphur at 12 and 24DH. In the post-harvest treatments, Calcarea carbonica was evaluated at 6, 12, and 24CH (centesimal hahnemanian dilution) fruits being deaped into the respective treatment. The nosode of S. aculeatissimum at 12 and 24DH increased the total content of soluble solids (Brix degree) which attribute enhances the flavor and quality for industrialization. Calcarea carbonica treatment in post-harvest did not interfere on the chemical and physical attributes of tomato fruits, although Calcarea carbonica 24CH delayed the fruit softening.
