Abstract
In this paper we study the Reiter $P_{2}$ condition for commutative hypergroups and give necessary and sufficient conditions for $x \in \mathrm{supp}\, \pi$, where $\pi$ is the Plancherel measure. Finally we apply general results to characterize $\mathrm{supp} \, \pi$ in the case of polynomial hypergroups.
