  Electron transport properties of titanium nanowires were experimentally
studied. Below the effective diameter $\lesssim$ 50 nm all samples demonstrated
a pronounced broadening of the $R(T)$ dependencies, which cannot be accounted
for thermal flcutuations. An extensive microscopic and elemental analysis
indicates the absence of structural or/and geometrical imperfection capable to
broaden the the $R(T)$ transition to such an extent. We associate the effect
with quantum flucutuations of the order parameter.
