Attempts to meet produces market demand are not always followed by research reports showing the impact of novel, intensive cropping systems on the environment, human and animal health, and eventual chemical and structural changes of plants. This work carries a comparative evaluation of the morphology and anatomy of cherry tomato fruits obtained from organic, conventional and hydroponic cropping systems. Fruits were collected at the free market in the greater Curitiba, Paraná, Brazil. For each culture method, 50 fruits their weight, diameter and volume measured. For the anatomical analysis, samples of the pericarp of ten fruits were excised and embedded in glycol methacrylate; 6-mm cuts were then obtained, stained with toluidine blue, and mounted on permanent glass slides. The anatomical analysis and illustrations were performed in Olympus and Zeiss photonic microscope. Samples obtained from the organic cropping system presented the highest mass, diameter, volume and density. The pericarp of fruits, obtained from the conventional cropping system presented larger but less abundant cells in comparison to the pericarp of the hydroponic and organic-produced fruits. |
