Abstract
Beet yellows virus (BYV) was mechanically transmitted by sap from sugar-beet plants, infected with BYV, to the plants ofChenopodium quinoa Willd. and ofChenopodium foliosum (Moench) Asch. Mechanical transmission of BYV to the plants ofTetragonia expansa Murr. failed. Infectious material was homogenized in phosphate buffer with veronal and EDTA, pH 7–8. Experimental plants were darkened three days before infection and kept at a temperature of 5°C. Plants ofC. quinoa Willd. were decapitated. Back transmissions fromC. quinoa Willd. andC. foliosum (Moench) Asch. infected with BYV, to sugar-beet plants were carried out by the aveidMyzus persicae Sulz. These transmissions were positive. Filamentous particles of BYV, of an average length 1275 nm, were found in plants ofC. quinoa Willd. andC. Foliosum (Moench) Asch., infected with BYV.
Abstract
Virus žloutenky řepy (beet yellows virus—dále BYV) byl přenesen mechanicky šfávou z rostlin cukrové řepy, infikovaných BYV, na rostlinyChenopodium quinoa Willd. aChenopodium foliosum (Moench) Asch. Na rostlinyTetragonia expansa Murr. se BYV nepodařilo mechanicky přenést. Infekční materiál byl homogenizován ve fosfátovém pufru s veronalem a EDTA o pH 7,8. Pokusné rostliny byly před infekcí 3 dny zatemněny při teplotě 5°C. RostlinyChenopodium quinoa Willd. byly dekapitovány. Z rostlinChenopodium quinoa Willd. aChenopodium foliosum (Moench) Asch., infikovaných BYV byly provedeny zpětné přenosy na rostliny řepy cukrové mšicíMyzus persicae Sulz. Tyto přenosy byly pozitivní. V rostlináchCh. quinoa Willd. aCh. foliosum (Moench) Asch. infikovaných BYV byly zjištěny vláknité částice BYV průměrné délky 1275 nm.
