Resumo
Concentrations of K+
and 137Cs+
in tissues of the Citrus aurantifolia were measured both by
gamma spectrometry and neutron activation analysis, aiming to understand the behavior of monovalent
inorganic cations in plants as well as its capability to store these elements. In contrast to K+
, Cs+
ions are not
an essential element to plants, what might explain the difference in bioavailability. However, our results have
shown that 137Cs+
is positively correlated to 40K+
concentration within tropical plant species, suggesting that
these elements might be assimilated in a similar way, and that they pass through the biological cycle together.
A simple mathematical model was also proposed to describe the temporal evolution of 40K activity
concentration in such tropical woody fruit species. This model exhibited close agreement with the 40K
experimental results in the fruit ripening processes of lemon trees.
