摘　　要：Li et al. in [3] obtained blow-up results for a system of Petrovskey equations in some different cases. In this article we obtain lower bounds for the blow up time under some considerations on initial data.Li et al. in [3] obtained blow-up results for a system of Petrovskey equations in some different cases.
