Apple cultivars resistant to scab (Venturia inaequalis (Cke.) Aderh.) Part II. Winterhardiness of apple cultivars
The severe winter which occurred in Poland in 1986-1987 damaged the most part of scab resistant apple cultivars and selected apple hybrids. Cold hardiness studied in 1987 and 1988 showed significant differences in degree of frost injury on stem, branches, twigs and buds of apple trees. Two scab-resi...
