Effect of Fe-deficiency on root development of tomatoes. (a) The primary root length. (b) The total lateral root number of the whole root system. (c) The lateral root density, expressed as the lateral root number per gram fresh weight. (d) The lateral root number on the 15 cm root tip (i.e. the main root section with a 15 cm length from the root tip). (e) The picture of the tomato roots. The tomato plants were grown for 6 d in nutrient solution that contained (+Fe) or omitted (−Fe) Fe-EDTA. Data are means ±SD (n=8). Different letters indicate significant differences (P <0.05) between treatments.
