Data obtained from Table 2 in Panno et al., 2012.
Nv, number of viruses per plant.
Nm(%), number of plants and percentage (between parentheses) of uninfected (Nv = 0), or with single (Nv = 1), double (Nv = 2), triple (Nv = 3), quadruple (Nv = 4), or quintuple (Nv = 5) infections.
Viruses: Pepino mosaic virus (PepMV), Tomato spotted wilt virus (TSWV), Tomato torrado virus (ToTV), Tomato chlorosis virus (ToCV), Cucumber mosaic virus (CMV), Tomato mosaic virus (ToMV) and Tomato infectious chlorosis virus (TICV). “+” indicates the presence and “−” the absence of a virus.
NC (%), number and percentage of plants infected by different virus combinations.
Ni (%), number and percentage of plants infected by each virus.
