Changes in Polyamines Related with Pruning as a Method for Rejuvenation in Filbert
Polyamine titer in leaves taken from mature and severely pruned trees (two successive treatments) of filbert (Corylus avellana L. cvs Gironella and Negreta) was investigated in order to determine the possible relationship between polyamine levels and the degree of juvenility of the plant material achieved by pruning. The results revealed different patterns in the polyamine metabolism, probably related to the effectiveness of the pruning, based on the increase of rooting as an indication of rejuvenation.
