Mechanical Transmission of an apple mosaic virus

Hilgardia, 1955, vol. 23, issue 15

Abstract: Virus diseases of fruit trees are rarely transmitted by mechanical means. A virus from apple mosaic has been transmitted mechanically to tobacco, Nicotiana glutinosa, tomato, cucumber, globe amaranth, sunflower, broad bean, French bean, cowpea, guar, and pokeweed, but not to apple. Evidence that the virus which was transmitted mechanically was actually apple mosaic rests on the transmission of the infection from tobacco to apple by means of dodder, with symptoms on apple similar to those of the original natural infection.
