Abstract
Iodine is vital to human health, and iodine bio-fortification programs help improve the human intake through plant consumption. Essential processes in plants that can be altered by iodine bio-fortification include the nutritional state of plants. The main objective of this work was to determine whether mineral nutrient concentrations were affected by the application of different forms (iodide [I−] vs. iodate [IO3 −]) and dosages (0, 20, 40, and 80 μM) of iodine, to ascertain the influence of this trace element in Lactuca sativa var. longifolia plants. The application of 80 μM of I− significantly reduced the nutrients nitrogen (N), phosphorus (P), and potassium (K) to below the optimal ranges established for this crop. The IO3 − treatments represented optimal maintenance of the nutritional state for most of the nutrients and even an improvement of nutrients as important as magnesium (Mg) and iron (Fe).
