Winter frost resistance of some grapevine varieties was tested after the very cold 1985 january. Buds frost damages were estimated in relations to bud position on vine-shoots and to the severity of damage on the bud-axes. The most resistant cultivars were Pinot grigio, Barbera and Chardonnay; on the other hand the less resistant ones were Ciliegiolo and Trebbiano romagnolo. During the 1986 season, this results were confirmed by vegetative and productive behaviour of each variety.

Abstract
Winter frost resistance of some grapevine varieties was tested after the very cold 1985 january. Buds frost damages were estimated in relations to bud position on vine-shoots and to the severity of damage on the bud-axes. The most resistant cultivars were Pinot grigio, Barbera and Chardonnay; on the other hand the less resistant ones were Ciliegiolo and Trebbiano romagnolo. During the 1986 season, this results were confirmed by vegetative and productive behaviour of each variety.
