N2 - We discuss the determination of the (flavour) SU(2) symmetry breaking due to the u and d quark vacuum condensate ratio, 1 - 〈dd〉/〈uu〉 {reversed tilde equals} 0.022-0.027, from QCD sum rules. We also comment on the SU(2) breaking for the ωρ{variant}π couplings and its relevance in ω, φ{symbol} → π+π-π0 and ω, ρ{variant} → πγ decays. © 1984.
