Abstract:
The vegetative propagation of adult trees requires special 'rejuvenation' techniques for plant material to regain morphophysiological conditions favourable to rooting (Chaperon, 1979; Franclet, 1983).
Rejuvenation is achieved by means of an initial graft of adult material for 'mobilization', followed by a number of successive grafts of the new shoots onto very young rootstocks.
This technique is commonly known as 'successive grafting'.
In the present investigation, this procedure was used to rejuvenate selected trees of Eucalyptusxtrabutii, a hybrid of E. camaldulensisx E. botryoides.
