[en] We calculate the hadronic coupling constants gNNπ and gρππ in QCD, including dynamical quarks in the framework of staggered fermions in the lattice approach. For the nucleon-pion coupling we obtain gNNπ=13.8±5.8, to be compared with the experimental value 13.13±0.07. The ρππ coupling has been analysed for two different sets of operators with the averaged result gρππ=4.2±1.9 which is to be compared with the experimental value 6.06±0.01. (orig.)
