Abstract
One year old apple shoots of Belle de Boscoop cv. were subjected to artificial freezing.
The injury inflicted by low temperature was estimated on the basis of survival test, diffusion of electrolites and the measurement of electrical admittance.
It was concluded that the method of electrical admittance of the shoots showed to be less reliable than the other two methods for the evaluation of the injuries suffered by apple shoots during artificial freezing.
Survival test and the diffusion of electrolites from the shoots gave more reliable results /table 1/. The study of regeneration potential of potted and frozen Antonovka seedlings showed that 80 % of the seedlings rated after freezing at "3" regenerated, and only 20 % had perished.
The obtained results indicated that seedlings rated at "3" /according to survival scale /Holubowicz and Bojar, 1977/ were able to survive the initial temperature stress.
