The interaction between two heavy metals (essential or not) and the way it affects plant growth have been previously investigated. Agarwala et al. observed that an excess of Mn, Cu, Zn, Co and Ni reduced Fe uptake by barley plants and affected its distribution in roots and shoots. Polar and Kucukcezzar verified a considerable Mn decrease in Lemna gibba (L.) fronds as a result of increasing concentrations of Cd in the culture medium. In the Sado River estuary (South of Portugal), the halophyte Halimione portulacoides (L.) Aellen often colonizes the banks of creeks (silty-loam soils), or constitutes a buffer between terrestrial and estuarine habitats (sandy soils) with a pH ranging between 7.2 and 7.95. This species accumulates high levels of Cu and Zn in spite of the low levels in the substratum. The pattern of accumulation of different concentrations of Cu and Zn by H. portulacoides cultivated in vitro was studied by Reboredo. The effects of each concentration of Cu on the Zn content of the species and vice-versa, as well as on Fe and chlorophyll a and b levels were also investigated, although not included in the above-mentioned work. The present study describes those results using an analysis of variance to examine the differences of metal levels between exposure times, organs and tested concentrations. 17 refs., 6 tabs.
