Popis:	The present paper deals with the results of photoelectric observations of 70 components of 19 Trapezium-type multiple systems in Stromgren and Crawford six-colour photometric systems. The trapezia were selected from the Abastumani Catalogue. Observations were carried out with the automatic and computer controlled 125-cm Ritchy-Cretien telescope (F = 1590 cm) at the Abastumani Astrophysical Observatory. The results are listed in Table 1. In conformity with the Stromgren criteria the components were ascribed to B, AF and A spectral classes (Table 2). Absolute magnitudes of the components were determined and effective temperatures and gravitational forces on the stellar surface calculated.
