Resistance to water flow in xylem of Picea abies (L.) Karst. trees grown under contrasting light conditions

  title={Resistance to water flow in xylem of Picea abies (L.) Karst. trees grown under contrasting light conditions},
  author={Arne Sellin},
The relative hydraulic conductivity (k) of xylem and resistance (R) to water flow through trunk, primary roots and branches in Picea abies trees growing under contrasting light conditions were investigated. The xylem permeability to water was measured by forcing 10 mM water solution of KC1 through excised wood specimens. From the values of k, the sapwood transverse area and the length of conducting segments, R of the whole trunk, branches and roots was calculated. The relative conductivity of… CONTINUE READING
