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

Fig. 3. Average canker area in black walnut trees following inoculation with four Geosmithia morbida isolates representing different rDNA ITS haplotypes, under greenhouse conditions in May 2010. Means not followed by the same letter are different (P = 0.05) using Tukey HSD adjustment for multiple comparisons. Values were averaged over three black walnut families. Bars represent standard deviations.
