Abstract
Ethylene or ethane was added to and sampled from the base, middle and top of the stem of intact Picea abies (L.) Karst. using microdialysis probes. The endogenous concentrations of ethylene and ethane in all positions were below 5 × 10−9 mol l−1 throughout the experimental period. Applied ethylene or ethane was always detected in probes above the probe used for the application, never below. If increased ethylene or ethane concentrations were detected, the ethylene concentrations initially increased but thereafter decreased to the basal level, whereas levels of ethane steadily increased. It is proposed that the maintainance of low ethylene levels is important in the regulation of wood formation.
