Sažetak
All isolates of CMV obtained from squash (Cucurbita pepo L.), peppers (Capsicum, annuum L.), beans (Phaseolus vulgaris L.) and lettuce (Lactuca sativa L.) caused similar symptoms typical of CMV in Cucumis sativus Delicatess, Datura stramonium, Nicotiana glutinosa, N. megalosiphon, N. tabacum White Burley and Chenopodium amaranticolor. The reactions of other test plants showed differences existing among some isolates.
The H isolate from C. pepo differed from V isolate obtained from the same species by systemically infecting C. quinoa, and by more severe reactions of C. pepo and C. maxima. Both isolates caused local lesions in Vigna sinensis Midget and no reaction in P. vulgaris Top Crop.
All isolates from C.annuum except one provoked only local lesions in P. vulgaris and V. sinensis.
All isolates obtained from local selections and from imported varieties of P. vulgaris, including two isolates obtained from L. sativa, behaved similarly causing local and systemic infection of P. vulgaris and V. sinensis.
In serological tests performed in agar gel the isolates from C. pepo gave precipitin lines nearer to the antiserum well characteristic of degraded virus, while the precipitin lines formed by all other isolates were near the antigen wells showing that more stable antigen reacted.
The results presented show that in CMV infections of the observed vegetable species at least three different strains participated including five variants, one strain of which is common in beans and lettuce crops.
