    Allometric relationships for surface area and dry mass of young Norway spruce aboveground organs by R. Pokorný, I. Tomášková

    Published 2007-12-01
    “…Tree-level allometric functions for a precise predicting of stem, branch and leaf mass and surface area of three needle-shoot age classes were estimated from measurements of crown and stem dimensions in 34 harvested Norway spruce (Picea abies [L.] Karst.) trees. Trees were grown within a 16-years-old stand in the Beskids Mountains. …”
