Abstract
The trace element content of red spruce foliage exhibits seasonal changes which vary with the crown position, tree and tissue age and the particular element considered. Tree age has a significant effect on trace element content while crown position has a less striking influence. New foliage growth, when compared to 1 yr old needles, also exhibits differences. The mean levels of trace elements contained in red spruce foliage ranged from 1231-1915 ppm Mn, 32.8-50.8 ppm Fe, 14.5-18.4 ppm B, 5.5-6.6 ppm Cu, 52-88 ppm Al, 19.0-26.6 ppm Zn and 0.023-0.030 ppm Mo.This publication has 4 references indexed in Scilit:
