Abstract

A simple routine procedure for testing frost hardiness of woody species has been worked out, using Pinus silvestris (L.) as the experimental plant. Shoots or twigs are placed in deep-freezes maintained at different temperatures. The rate of cooling of the plant tissues depends on the temperature of the deep-freeze. It is more rapid than the rates usually employed in freezing tests. The merits and disadvantages of this freezing method are discussed. The degree of injury is determined by a modification of the conductivity method. The procedure has been used for determining changes in frost hardiness of Scots pine from October to May. The values obtained are reproducible, and even small changes in degree of hardiness of very hardy plant tissues may be determined by the method.
