We estimate coupling constants of g/sub T/'s to two pions as well as two gluons from the experimental ratio of sigma(..pi../sup -/p..-->..g/sub T/n) to sigma(..pi../sup -/p..-->..f'n). We can evaluate decay rates of g/sub T/ into pairs of pseudoscalar and vector nonets as well as GAMMA(psi/J..-->..g/sub T/..gamma..)/GAMMA(psi/J..-->..f'..gamma..) in a rather model-independent way. Our estimates are consistent with the hypothesis that g/sub T/'s are all glueballs, or at least one g/sub T/ is a glueball. We also estimate B(theta..--> pi pi..)B(theta..-->..etaeta)<1.3 x 10/sup -3/ for the product of decay branching ratios of theta(1700 MeV) meson.
