Phenolic compounds distribution along the lenght of Scots pine needles in a polluted and control environment and its connection with necroses formation

Abstract

Phenolic compounds distribution was studied along the length of Scots pine needles from trees in a polluted and a control site. There is no significant difference in the content of total phenols between the studied sites. There are significant differences in distribution of phenolics along the length of needles. The highest content is in the tip part of the needle and the lowest at the base. This kind of distribution suggests a role of these compounds in the processes of necroses formation. The content of phenolic compounds is positively correlated with the toxic elements - fluorine and aluminium and negatively with the macroelements - phosphorus, potassium and magnesium.
