abstract:
The agamic propagation ofQuercus suberL. could be useful for the genetic improvement of
the species and could have noticeable advantages in forest nursery practices.
For this purpose we have tried some experiments of in vitro cultures of tips obtained from
vigorous new shoots collected from a cork-oak grove which had been affected by fire.
The developmental stage ended with the sprouting of 25% of the tips. The two following
subcultures showed an average rate of multiplication of 3.6:1. The 82.5% of the shoots that
had been cultured gave off roots, but produced very small plants due to the poor growth of
the shoots during the previous elongation stage.
