Freeze Damage to Southern Pine Seedlings in the Nursery
The December 1983 sudden temperature drop with prolonged freezing temperatures damaged significant numbers of pine seedlings in southern nurseries. Seedlings from southeastern Oklahoma and east Texas to north Florida and south Georgia were affected by freezing temperatures damaging non-frost-hardy tissues. The primary tissue affected was the cambium. Damage extended from the root collar well into the root system. Symptoms included reddish-brown bark and brown cambium. Effective diagnosis required cutting through the root bark to expose the discolored cambium and cortex.
