| dc.description.abstract | A series of experiments was carried out to support or negate the hypothesis that depressed root temperatures have an immobilizing effect on the translocation of tobacco mosaic virus within tobacco and tomato plants or inhibit virus multiplication in invaded tissue. Translocation of TMV from the inoculated leaves of systemic hosts was delayed when roots were kept at 7 C. Multiplication of translocated virus was also inhibited by low temperatures as indicated by results obtained from tissue incubation prior to assay, lesion counts on cold treated local lesion host, and serological tests. The mobilization and multiplication inhibition phenomenon was inversely correlated with decrease in temperature. ... | en |
