Kinetics of δ¹³C (in ‰) in leaves of the hazel tree A11 after pulse labeling and δ¹³C of buds and branches sampled during the winter following the pulses.

One-way Anova has been performed using R; data have been raised to power minus 2 prior to Anova as suggested by the Box-Cox method in order to ensure the normality of residuals. Standard errors of means are given in brackets and mean values followed by a different letter are significantly different from the others at p<0.05 (Mean comparison Tukey’s test).
