Effect of <i>Geosmithia morbida</i> Isolate and Temperature on Canker Development in Black Walnut

Fig. 2. Average canker area in black walnut half-sibling families following inoculation with four isolates of Geosmithia morbida, representing three rDNA ITS haplotypes, in the greenhouse in October 2009. Values were averaged over four G. morbida isolates. Means not followed by the same letter are different (P = 0.05) using Tukey HSD adjustment for multiple comparisons. Bars represent standard deviations.
