The influence of nuclear effects on the transverse momentum (p{sub T}) of neutrino-produced hadrons is investigated using the data obtained with the SKAT propane-freon bubble chamber irradiated in the neutrino beam (with E{sub {nu}} = 3-30 GeV) at the Serpukhov accelerator. It has been observed that the nuclear effects cause an enhancement of <p{sub T}{sup 2}> of hadrons produced in the target fragmentation region at low invariant mass of the hadronic system (2 < W < 4 GeV) and at low energies transferred to the hadrons (2 < {nu} < 9 GeV). At higher W and {nu}, no influence of nuclear effects on <p{sub T}{sup 2}> is observed. Measurement results are compared with predictions of a simple model, incorporating secondary intranuclear interactions of hadrons, which qualitatively reproduces the main features of the data.
