We derive a set of sum rules for threshold parameters of {pi}-{pi} scattering whose dispersion integrals are rapidly convergent and are dominated by {ital S}- and {ital P}-wave absorptive parts. Stringent constraints on some threshold parameters are obtained. {copyright} {ital 1996 The American Physical Society.}
