Abstract
A dedicated test of the perturbative QCD NLO parton evolution in the very small- region is performed. We find a good agreement with recent precision HERA-data for , as well as with the present determination of the curvature of . Characteristically, perturbative QCD evolutions result in a positive curvature which increases as decreases. Future precision measurements in the very small -region, , could provide a sensitive test of the range of validity of perturbative QCD
