As part of an ongoing project aimed at studying the age and metallicity gradients of the stellar populations along the bars of a sample of barred spirals of different morphological types, we present our first results on NGC 4314 (SBa). We have obtained optical and NIR colours and spectral indices along the bar and we interpret some of these results here and discuss their uncertainties on the basis of single stellar population models. In a preliminary analysis, we constrain the limits for the age and metallicity of the nucleus and two selected regions in the star formation ring of NGC 4314, characterizing both as metal rich (Z
