Let K be an algebraically closed commutative field of characteristic 0. We prove the equivalence between stability and quasi-reductivity for biparabolic subalgebras of reductive Lie algebras. Therefore, we give a positive answer to the assertion (ii) of the conjecture (5.6) of D. I. Panyushev [An extension of Rais' theorem and seaweed subalgebras of simple Lie algebras, Ann. Inst. Fourier (Grenoble) 55 (2005) 693--715].
