| Abstract:
The results of cytological investigations of herbaceous host plants (Chenopodium foetidum and Nicotiana glutinosa) and woody plants (Prunus domestica cv. Green gage and Prunus domestica cv. Italian Prune), experimentally infected with plum pox virus are presented. The studies were carried out on leaf tissues and phloem of shoots. In the cytoplasm of parenchyma cells elongated particles, 760–780 nm length and 20–24 nm in diam. (Fig. 1) as well as “pinwheel” structures were observed (Figs 1, 4). The cytopathological structures: vesicles (Fig. 5), paramural bodies (Figs 3) and nonidentified material deposited into the cell walls have been seen (Figs 2, 3). In the sieve elements of leaves of herbaceous and woody plants the “pinwheel” structures were identified but the virus particles have not been observed | |
