520			_aThe kinetics of maize (Zea mays L.) infection by barley yellow dwarf virus (BYDV) was studied in a glasshouse. Young plants (5 to 7 leaves) were infested with viruliferous Rhopalosiphum padi (L.) carrying a PAV isolate of BYDV. Sampling for enzyme-linked immunosorbent assay (ELISA) was carried out at a range of times after inoculation. Ten days after inoculation the optical density (OD) values obtained with ELISA were high in the roots (OD = .750) and very low in the leaves (OD = .090). Later (30 or 40 days), the OD values were high both in the roots and in the upper leaves. After 40 days, the OD values decreased in the whole plant. Another
