At the end of winter dormancy, which is about mid-January, both varieties begin to deacclimate again, the rate depending on temperature. Gala lags behind Golden Delicious in acclimating in the autumn but becomes equal in resistance about Christmas. Braeburn acclimates very slowly, even compared to Golden Delicious and Gala. There are only a few days between the time the tree stops growing and vegetative maturity. It deacclimates very easily even during the winter dormant period and deacclimates very rapidly in the spring.
Pears respond to nurture much earlier than most apple varieties.
Anjou and Bartlett respond to low temperature more than Bosc and therefore attain more hardiness.
