In the last few years several reports on maturation and rejuvenation have appeared (Greenwood, 1987; Bonga and Durzan, 1987; Monteuuis, 1988) but discussions on this controversial area are common and still represent a phenomenon which is only partially understood due in part to the complexity of the physiological processes involved and of course due to the difficulties found in timing this period in the plant cycle. However most authors agree that maturation and aging seem to be responsible for the morphogenic potential decline found in most woody species. As is common, micropropagation pathways found in filbert (Corylus avellana L.) are strongly linked to the chronological age and of course to the ontogenical and physiological changes related; situations that may be at least partialy exogenously manipulated and probably reversed.
