Fig. 3From: Fire effects on a fire-adapted species: response of grass stage longleaf pine seedlings to experimental burningSurvival by treatment near the end of the second growing season (August 2014) after treatment application for (a) Large, (b) Medium, and (c) Small longleaf pine seedlings treated in South Carolina, USA, in January and May 2013. The P-values indicate significance from the Mantel-Haenszel test for treatment effect, and the same letter within an application month indicates no significant difference in Pearson chi-square pair-wise comparisons. An asterisk (*) indicates a significant difference in survival between the January and May treatment applications by treatment and seedling size class. Cross hatching on bars illustrates the percentage of the original seedlings that survived by sproutingBack to article page
