The frost resistance of the root systems of own-rooted 22-year-old apple trees of a number of varieties was estimated by exposing the roots to temperatures of -12 degrees , -14 degrees and -16 degrees C. and observing the damage caused under a microscope. The variety Kitajka Volzskaja was the most frost resistant and Pepin Safrannyj the most sensitive. A certain amount of variation in resistance was found within varieties.
