Summary Conditions necessary for the detection of potato leafroll virus (PLRV) and potato virus Y (PVY) in tubers from primary and
secondary infected plants were investigated. Tubers were analysed before and after breaking dormancy by rindite treatment.
PLRV was reliably detected indormant tubers whereas PVY was readily detected only when tubers had been rindite-treated and
held for two to three weeks at 22°C and high humidity in the dark. PLRV occurred in higher concentration at the heel end than
at the rose end of infected tubers and the concentration remained nearly unchanged during the experimental period of 35 days,
whereas PVY was found to be more concentrated at the rose end and was rapidly accumulating in the tubers after the break of
dormancy. In dormant tubers PVY concentration dropped during storage at 22°C. The use of ELISA for tuber indexing is discussed. 相似文献
