Resumo: The genus Physalis L. has great importance in the framework of Brazilian biodiversity especially in the Amazon region. The use of colored shading nets allow manipulating the light spectrum, and thus supplying the appropriate quantity and quality of light for each species and maximizing production. The purpose of this study was to evaluate the effects of shade nets on fruit production and qualitative parameters of four species belonging to genus Physalis. The experimental design was random blocks with a 4 x 5 factorial scheme, four species of Physalis (P. peruviana, P. pubescens, P. minima and P. ixocarpa) and four colors of shade nets (white, blue, red and black), besides the control treatment under full sun exposure. Fruits were collected weekly and evaluated for longitudinal and transversal diameter and biomass with and without a calyx. Finally the percentage of calyx biomass compared to the total fruit biomass, number of fruits per plant and production were determined. A differentiated response was found among the species regarding the coloring of the converter shade nets. Plants of P. peruviana had the best productive and qualitative parameters of fruits when cultivated in full sunlight or under white shade nets, P. pubescens and P. minima when cultivated in full sunlight or under white and blue shade nets, and P. ixocarpa under red or black shade nets.
