Abstract: The next to lowest mass scalar multiplet is treated as the $q\bar{q}$,$P$-wave nonet, weakly mixed with the lower - mass, presumably $qq\bar{q}\bar{q}$$S$-wave nonet and, in principle, with the $J^{PC}=0^{++}$ -glueball.The modified Gell-Mann-Okubo-type mass-formulas are used to deriveand discuss the quark-gluon configuration structure of the obtainedmeson states which are then used to obtain the relations between thedecay ratios $Br(J/\psi \to \omega f_{0})$/$Br(J/\psi \to \phi f_{0})$,where $f_{0}(1720)\cong G$ is the glueball, the $f_{0}(1370)$ and$f_{0}(1506)$ are quarkonium states. Some other relations betweenthe radiative and radiationless decays of the lowest mass charmoniumstates into scalar resonances are presented and discussed.T = On possible role of scalar glueball-quarkonia mixing in the f(0)(1370,1500,1710) resonances produced in charmonia decays
