Zur wirkung einiger morpholinoverbindungen auf die vermehrung von RNA-viren

Summary In the present paper the authors report about the effect of N,N-dimethylmorpholinium chloride (DMMC), N,N-dimethyl-2-oxomorpholinium chloride (DMOMC), and N,N-diethyl-2-oxomorpholinium chloride (DEOMC) on the multiplication of tobacco mosaic virus (TMV), potato virus X (PVX), and cucumber mosaic virus (CMV) as well as the plaque formation by the RNA phages M 12, f 2, and Qs. The used morpholinium compounds do not influence strikingly the multiplication of phytoviruses. The results found by serological procedure and by bio-assay are indicated concordantly by the two methods. The plaque formation by bacteriophages is not influenced by DMMC, but enhanced significantly by DMOMC and DEOMC. These effects might be caused by the different hydrolytical behaviour of the morpholinium compounds tested.
