We present the results of the investigation of correlations between the polarimetric and photometric characteristics of a sample (496 objects) of young Herbig Ae/Be (HAEBE) stars and T Tauri (TT) stars. It is shown that, for 85% of the sample stars there is a gen- eral relation between the degree of optical polarization and the infrared colour index (V L)obs and the colour excess E(V L) due to the contribution of a circumstellar dust shell. Polarimetric data were also compared with the value of v sini to search for a possible correlation between the polarization and an inclination of circumstellar disks. Polarimetric data as well as IR excesses are considered and compared for dierent subgroups of young stars namely: HAEBE and TT stars with Algol{like minima of bright- ness (26 objects), Vega{type stars and post HAEBE stars (114 objects) and young solar{type stars (58 objects). For statistical purposes the data for young stars were com- pared with those collected for dierent groups of evolved objects such as: classical Be stars (300 objects), Mira Ceti stars (39 objects), early{type supergiants from the Serkowski et al. (1975) catalogue (120 objects) and main sequence (MS) stars within 50 pc from the Sun from the Leroy (1993) catalogue (68 objects). The value of polar- ization is discussed in context with the stages of evolution of circumstellar shells which were established by compari- son of spectral energy distribution in the far IR (using the IRAS data). It is shown that most young stars have sta- tistically larger value of polarization in comparison with the stars which are on a stage of evolution close to MS. We are able to contend that the changes in polarimetric behaviour of young stars are connected with evolution of their circumstellar shells.
