Abstract
Galactic planetary nebulae (PN) form a complex system, which includes objects with different characteristics and evolutionary stage. The loc ation of a sample of galactic PN central stars on the HR diagram is at tempted, in order to investigate the correspondence of the PN properti es such as chemical composition, space distribution and kinematics, wi th the main sequence masses of their progenitor stars.
