Unformatted text preview: pendent variables were the three yield components and the independent variables were pathogens, years, and cultivars, including interaction terms among these three factors. Similarly, Evans et al. (3) used MANOVA to examine differences in host penetration and colonization by Alternaria linicola in three genotypes (susceptible, moderately resistant, and resistant) of Linum usitatissimum. Dependent variables were associated with host penetration and colonization, and the three genotypes were independent variables. There are scenarios in which response variables are temporally and spatially dependent. As an example, consider an experiment designed to assess the effect of several fungicides on the severity of a disease in a set of crop cultivars, and that disease severity (DS) was recorded at four time points (t1, t2, t3, and t4) yielding disease severity values of DS1, DS2, DS3, and DS4, respectively. Typically, these DS values at the four time points are correlated, and thus are not independent. The exi...
