| Abstract:
The potato aucuba mosaic virus (PAMV) was isolated from the potato cv. Shepody. The infected plants featured yellow patches on the lower leaves and slight deformation. Nicotiana glutinosa plants infected with the studied isolate displayed light green mottle and vein-banding, along with some deformation on newly formed leaves. The Capsicum annuum and the C. frutescens reacted with necrotic spots and rings, as well on the inoculated leaves as on the new ones. Most of the inoculated pepper plants were killed due to infection. The N. tabacum cv. Samsun and the Chenopodium amaranticolor were not susceptible to the studied PAMV isolate. The thermal inactivation point of the studied virus isolate is at 58 ° C, the dilution end point 10-4 and the longevity in vitro up to 3 days. The virus particles are filamentous of the most frequent length of 575 to 600 nm. | |
