  In the present work, we study correlations between stellar fundamental
parameters and the oscillation amplitude for delta Scuti stars. We present this
study for a sample of 17 selected delta Scuti stars belonging to 5 young open
clusters. Taking advantage of properties of delta Scuti stars in clusters, we
correct the photometric parameters of our objects for the effect of fast
rotation. We confirm the benefit of applying such corrections in this kind of
studies. In addition, the technique used for this correction allows us to
obtain an estimation of stellar parameters like the angle of inclination and
the rotation rate, usually not accessible. A significant correlation between
the parameter i' (estimation of the angle of inclination of the star) and the
oscillation amplitude is found. A discussion and interpretation of these a
priori surprising results is proposed, in terms of a possible selection rule
for oscillation modes of delta Scuti stars.
