Özet

New relations between QCD Borel sum rules for strong coupling constants of K-mesons to baryons are derived. It is shown that starting from the sum rule for the coupling constants g(pi Sigma Sigma) and g(pi Sigma Lambda) it is straightforward to obtain corresponding sum rules for the g(KYN), G(KY Xi) couplings, Y = Sigma,Lambda.
