(1991): SITE-SPECIFIC DIFFERENCES IN CALCIUM-OXALATE CONTENT OF THE SECONDARY PHLOEM OF SPRUCE (PICEA-ABIES KARST)
FLORA. 1991; 185(6): 377-384.

Abstract:
Anatomical and histochemical features of the secondary phloem of spruce trees from sites on calcareous and on crystalline substrate were investigated. Phloem anatomy showed no site-specific peculiarities. Pronounced differences became evident in the occurence of calcium oxalate, which forms characteristic crystals in the phloem parenchyma; spruce trees from the calcareous site contain large amounts thereof. Vastly different calcium contents of soil solutions were not reflected in the composition of xylem saps from the two sites. Results from attempts to demonstrate calcium distribution by means of chlorotetracycline fluorescence suggest a depletion of xylem sap calcium due to radial transport in ray parenchyma.
