Abstract
The studies of the resistance of apple accessions to spring frosts have been generalized in this paper. As a result of the artificial freezing, flowers and buds of the studied apple accessions demonstrated high resistance to the spring frost –1,0 °С. The damage of flower pistils did not exceed 10,0 %. The most of the experimental apple accessions showed resistance of flowers and buds at a temperature of –2,0 °С. The damage level did not exceed 25,0 %. The temperature of –3,5 °С became critical for the flowers of most apple accessions.
