A rotor for a turbomachine has slots formed therein at an angle to an axis of rotation of the rotor. Blades have at least one blade root with at least two regions of different rigidity that are adapted and preferably matched to different regions of rigidity of the slot. The blade roots can be fitted into the slots. A blade for a rotor is also provided. The invention is especially suitable for use in gas-turbine compressors, as a result of which local stresses at slots can be greatly reduced.
