The comparative analysis of solar and Procyon spectral line bisectors is carried out. The interpretation of the basic features of solar and Procyon spectral line bisectors is given on the basis of the theoretical inhomogeneous models of their atmospheres and also on the basis of stochastic approximation theory of spectral line formation. The conclusion is made that the main differences between the Sun and Procyon are caused by the differences of correlation between of the temperature and vertical velocity fluctuations in their atmospheres.
