| Summary: | In this study, the effect of Cd on the germination, growth of seedlings and
composition of plants deriving from contaminated grains, grown in the field,
was examined. Wheat grains were soaked in Cd-containing solutions: 0
(control, deionized water), 10-5, 10-4, 10-3, and 10-2 M CdCl2 during 24h.
One portion of grains was used to test germination and seedling growth,
while the other was sown in the field. The concentration of Cd in the grains
almost linearly increased with the increase in the applied concentrations of
Cd, which reduced the germination and energy of germination and increased
the proportion of atypical seedlings. Larger concentrations of Cd
significantly impaired the growth of seedlings (length of the shoots and
roots, dry matter mass). In the grains of the field-grown plants the
concentrations of N, P, and K were not affected by Cd, but their
concentrations in the straw declined (especially of N). These results
suggest that the emergence and development of plants on the soil polluted by
Cd are likely to be significantly limited and yield reduced. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. TR 31016]
