In the present paper the peculiarities of schlieren textures of lyotropic nematic mesophases have been investigated by polythermic polarization microscopy and capillary temperature wedge methods. The lyotropic nematiccalamitics (N_{c}) and lyotropic nematic-discotics (N_{d}) formed in binary and ternary systems on the base of tetradecyldimethyl amino bromide and tetradecyldimethyl amino oxide have been the subjects of our investigations. The dynamics of time and temperature transformations of schlieren textures have been studied. The comparative estimation of schlieren textures of N_{c} and N_{d} mesophases has been performed. The optical force and optical sign of the schlieren textures observed have been determined.
