Studies on phenolic acids variation in Central European Pinus species 1. Five Polish populations of Pinus mugo Turra and some related forms

Abstract

Phenolic acids were investigated in the needles of eight different pine populations, five of which were Pinus mugo, two -- P. silvestris and one a critical form described by Neumann as P. uliginosa. Twenty different phenolic acids were detected. Six were discovered in pine needles for the first time (salicylic acid, gentisic acid, γ-resorcylic acid, o-hydroxyphenylacetic acid, β-resorcylic acid, p-hydroxyphenylacetic acid). Each of the investigated taxons was shown to exhibit a characteristic spectrum of phenolic acids. The critical form from the locus classicus of Pinus uliginosa is of intermediate character.
