Foliar injury symptoms and pigment concentrations in red spruce saplings in the southern Appalachians
Andersen CP, Mclaughlin SB, Roy WK. 1991. Foliar injury symptoms and pigment concentrations in red spruce saplings in the southern Appalachians. Canadian Journal of Forest Research. 21:1119-1123
The frequency and percent surface area covered by necrotic flecking on red spruce (Picea rubens Sarg.) needles from sapling-sized trees were examined on nine research sites on three mountains in the southern Appalachians. Foliar pigment analysis was conducted on trees from two of the nine research sites. Flecking increased with foliar age on all sites, and on two of the mountains the area covered by flecks increased with elevation. Above 1720 m on Cligman's Dome, foliar flecking was found to constitute...
