Abstract:
In order to enter into the food chain, the mineral elements have to be in a form accessible
for plants. In cultivated land, Cd originates from natural or anthropogenic sources. The
significant anthropogenic sources of Cd are the phosphorus fertilizers and the traffic pollution.
The way of the pea production and its use allow contamination of these plants with Cd. Considering
the effects of Cd on plants and animals, especially humans, the objective of our study was to
determine the intensity and dynamics of Cd retranslocation in the reproductive part of pea plant
that is used as food or raw material in food industry. The plants were subjected to treatment with
Cd at two concentrations (10–7 and 10–5 mol·L–1) in early and/or
late stage of development by using the solution culture method. The obtained results showed that
the accumulation, distribution, and retranslocation of Cd in the reproductive organs of pea depend
on the concentrations of Cd, and also on the age of the plant at the time of Cd application.
