- The response variable is pustule density (pustules per cm2 of leaf tissue) and was used as the response variable and it was log transformed before analysis. Log transformed inoculum dose (spores deposited per cm2) was used as a covariate. The interaction effect of pathogen genotype by inoculum dose was not significant and was removed from the model.
