8.0, plant leaves accumulated
higher Mn2+, but 80-87 mg Mn2+ kg-1 DM seemed sufficient for optimum
plant growth. With pMn2+ < 8.0, the concentration remained at the
optimum level in the CDTA-buffered solution, whereas in the EDTAbuffered
solution leaf Mn2+ concentration was in the range 193-241 mg
Mn2+ kg-1 DM. At pMn2+ < 8.0, leaf Ca2+ and Mg2+ were higher with
MnCDTA than with MnEDTA. Leaf Fe3+ concentration remained
constant and did not significantly change in response to Mn availability.
Fe: Mn ratio decreased with increasing Mn availability in the EDTA and
CDTA solutions.
CDTA-buffered solution offers a strong control of plant uptake of
Mn2+ due to its strong control of the free concentrations of Mn2+, Ca2+
and Mg2+ under conditions of limited Mn availability.]]>
