- The response variable is total spore production (mg spores per cm2 of leaf tissue) and it was log transformed before analysis. Log transformed inoculum dose (spores deposited per cm2) was used as a covariate. The effects of block (inoculation day) and pathogen genotype were analyzed at the whole-plot level, while the effects of inoculum dose, host genotype, and the interaction term, pathogen x host genotype, were analyzed at the split-plot level.
