Observation The two PAV isolates multiplied similarly to wild isolates in maize hybrid leaves.
Observation PAV was detected in maize leaves during the same postinoculation period in two of three years.
Observation Under high temperatures, PAV remained in maize roots for long periods.
Association Blocked PAV migration or multiplication was accompanied by less maize reddening.
Intervention effect High early PAV leaf infection reduced maize hybrid plant height by less than 10%.
Intervention effect High early PAV infection lowered maize grain yield by 15 to 20%.
Mechanism The yield loss reflected fewer maize kernels per ear.
Observation PAV infection did not change thousand-kernel mass.
Observation Maize yield loss did not vary with virus isolate or hybrid.
Observation PAV symptom intensity differed between maize hybrids.
