NITRATES IN THE CELULAR EXTRACT OF PETIOLES AND STEM OF HUSK TOMATO (<em>Physalis ixocarpa</em> Brot.) AND THEIR RELATIONSHIP WITH YIELD

This work was made with the objective to have information about the concentration of N-NO3 in the celular extract of petioles and stem of husk tomato in four phenological phases, for determining the relationship between this nutrimental index and yield. Six dif-ferent concentrations were evaluated using the Steiner’s nutritive solution at a hydroponic open system. The results showed a sig-nificant (P≤ 0.05) correlation between crop yield and the concentrations of the N-NO3 in the celular extract of petioles and stem, wich permited to know the nutrimental status of the plant at certain phenological phase and its relationship with yield.
