Influence of toxic metal ions phenols in needles and roots, and on root respiration of Scots pine seedlings

Abstract

Nitrates of aluminum, cadmium, manganese and lead cause changes in the content of phenolic compounds (o-dPh and TPh) in needles and roots, and in the rate of dark respiration (DR) of roots of one-year-old seedlings of Scots pine (Pinus sylvestris L.). The changes depend on the cation, the salt concentration used, and the analyzed plant part. The observed changes in the levels of phenolic compounds in needles and roots, and the rate of respiration in roots, indicate the following rank in toxicity of the studied metal cations: Mn < Al < Pb < Cd.
