Frost susceptibility and capacity for regeneration in apple and pear trees


, : Frost susceptibility and capacity for regeneration in apple and pear trees. Schweiz, landw. Forsch, 5: 268-302

Observations made following the severe winter of 1962-63 showed that hardiness was not a purely varietal character but changed with the age of the tree, was strongly influenced by the rootstock at the nursery stage and was affected by meteorological conditions and pruning.
