At Tbilissi, Prof. Blaauw (1975) reported on results of uvby photometry of F-type stars and showed a relation between the quantity Δm and the distance z to the galactic plane. This relationship could be interesting if Δm1 is a non ambiguous indicator of metallicity. It was found that the mean relative metal abundance decreases by a factor of about one third between 0 and 700 pc. The same type of relationship was obtained by M. Grenon (1976) for K giants and shows a lower variation of the metallicity with z.
