µM Ni in both Ni/Ni and B/Ni plants. For B/Ni plants, the root part developed in Ni-free
medium contained up to 325 µg Ni/g DW.
Figure 3. Changes in Cd concentration (µg.g
-1
DW) in the shoots and the roots of
S. portulacastrum
and
M. crystallinum
plants subjected to B/B (two halves of the root system in basal medium), B/Cd (one
half of the root system in basal medium and the other half in basal medium added with 100 µM Cd
2+
)
and Cd/Cd (two halves of the root system in basal medium added with 100 µM Cd
2+
) treatments. The
numbers inside the bars are the amounts of Cd accumulated in the shoots and the roots (µg.plant
-1
).
Means of 8 replicates. Bars marked with same letter are not significantly different at p= 0.05.
Potassium Status
Addition of 100 µM Cd
2+
, (Cd/Cd treatment), or 50 µM Ni
2+
, (Ni/Ni treatment), in the
medium culture reduced significantly the shoot K
+
concentration in both species (Figure 5A).
