Abstract
We argue that, in the Affleck-Dine mechanism, baryonic isocurvature fluctuations are generated in most inflation models in supergravity. The inflationary scale and a reheating temperature are constrained in order not to induce too large baryonic isocurvature fluctuations. In particular, high-scale inflation models with high reheating temperatures are disfavored in this context.
