The overall flood tolerance ranking is based on the weighted average comprised of the net photosynthetic rate (A) after 45 days of flooding, lenticel rating, and the percent survival. Values for the indicator JR trees are also presented but are not included in statistical comparisons.

H = High flood tolerance; significantly greater than 1 or L at P = 0.05 using Hsu’s multiple comparison test “smallest is best.”
I = Intermediate flood tolerance; those means that were not identified as the best using “largest is best” or “smallest is best” tests.
L = Low flood tolerance; significantly less than H or I at P= 0.10 using Hsu’s multiple comparison test “largest is best.”
