Abstract
The effect of iodine on development of tomato plants was studied by means of sand-water cultures and on plants grown in pots filled with soil. In sand-water cultures potassium iodide increased tangential growth at the expense of radial growth and decreased plant weight. Iodide treated plants tended to show accelerated cluster formation and earlier flowering. They also showed increased fruit yields. In soil cultures iodide dressings improved the fruit yield mainly by increasing the number of fruits. Where a comparison was made between different forms of iodine, iodide appeared to give better results than elemental iodine. The opinion, that the concentration of iodine compounds in the nutrient solution determines whether a beneficial or harmful effect of iodine will occur, has been confirmed.
