Can Bundled Seedlings Survive Freezing?

When trees are being planted, overnight storage outdoors is common practice, and not infrequently bundled seedlings are subject to freezing temperatures. How does this affect survival of the trees after they are planted? Following up on limited previous work in this field, TVA Division of Forestry De-velopment began a test in the spring of 1961 to find out how freezing affects bundled seedlings. The species involved were white pine, loblolly pine, and shortleaf pine. Normal storage temperature of 34 degrees F. was used as a check for comparison with two below-freezing temperatures-- 18 degrees F. and zero degrees F. Exposure times were 12 hours, 36 hours, and one week. To simplify data for the two below-freezing temperatures are combined in the table.
