Following the winter of 2005/2006, an assessment of frost damage was carried out
on the vines of fifty grape cultivars grown in the conditions of central Poland. The
minimum winter temperature of –31.6°C was recorded on 23 January 2006. The best
tolerance to extremely low temperatures (no damage to shoots or buds) was
shown by the American hybrids ‘Alwood’ and ‘Zilga’ of the Vitis labruscana
group. Some damage was found on the vines of the French-American hybrids
‘Marechal Foch’ and ‘Aurora’. The buds of the V. vinifera cultivars all froze. Frost
tolerance of the vines classed as interspecific hybrids varied from 45% of frozen
buds (‘Sibera’) to 100% (‘Medina’). Frost damage occurred on the shoots lying
above the snow line. The plant parts covered with snow were not exposed to
significant damage, even in susceptible cultivars.
