This communication turn on the use of Solanun gilo (Solanaceae) for lignification test on the nutritional point of view. This plant was chosen due its fast growth, high calcium mobility and low lignin content (15,51%). The experiment was carried out using calcium sulfate (CaSO4) and calcium chloride (CaCl2) for weekly and biweekly application. The treated plants with CaSO4/CaCl2 (biweekly application) showed 4% of additional lignin content. High syringyl unit concentration was also verified at Guaiacyl: Syringyl ratio (G: S) of 0.8:1 and 1.2:1, for weekly and biweekly application, respectively. The estimation of the lignin content and its composition were performed by Klason and infrared spectroscopy methods.
