Abstract
We review the predictions relative to the evolution of the [O/Fe] as a func tion of [Fe/H] in the Galaxy. In particular, we discuss the influence of di fferent stellar yields as well as different SN (II, I) rates on the [O/Fe] ratio. Possible explanations for the steep rise of the [O/Fe] ratio at low metallicities, as indicated by recent observations, are critically discusse d. (C) 2001 Elsevier Science B.V. All rights reserved.
