Fig. 1. Chlorophyll concentrations (Chl) as estimated by SPAD-502 meter during
Fe treatments: moderately Fe-deficient (Fe(−)/Day 20), severely Fe-deficient
(Fe(−)/Day 27), extremely Fe-deficient (Fe(−)/Day 42 and Fe-recovered plants
(Fe(−/+)/Day 50). Fe(+) and Fe(−) indicate solutions with 10 M of Fe (Fe-EDDHA) or
0 M of Fe, respectively. Values shown are means
±
SE of six measurements taken in
five leaves per treatment. Different letters indicate significant differences between
treatments (P < 0.05) according SNK test.
