AGE-SPECIFIC CONTENT OF CONDENSED TANNINS IN THE NEEDLES OF PICEA ABIES SSP. OBOVATA (LEDEB.) DOMIN
Siberian spruce (Picea abies ssp. obovata (Ledeb.) Domin) is one of the dominant species in north-taiga forests and changes in the chemical composition (e. g. tannins) of spruce needles can significantly affect biogeochemical cycles in the areas of its distribution. Variations in the tannin content...
