a) δ13C course of 1-year old bulk needle material (thin line), cellulose of 1-year-old (dotted black line) and 2–year-old (thick black line) twigs and phloem sucrose* (thick gray line) in the light during the vegetation period 2006; b) δ13C course of needle sucrose (thick gray line) and proteins (thick black line) in the light chamber during the vegetation period 2006. Dotted gray lines mark the halves of growing period. *Water soluble organic fraction consisted of ≥97 % sucrose. Data is shown as mean values ± SD (n ≥ 3)
