Colturain vitrodi apici vegetativi diQuercus suberL

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.
