Abstract: To every positive $ {C^r}$-quadratic differential form defined on an oriented two manifold is associated a pair of transversal one-dimensional $ {C^r}$-foliations with common singularities. An open set of positive $ {C^r}$-quadratic differential forms with structural stable associated foliations is characterized and it is proved that this set is dense in the space of positive $ {C^\infty }$-quadratic differential forms with $ {C^2}$-topology. Also a realization theorem is established.
