Abstract

The induced resistance to tobacco mosaic virus(TMV) in tobacco treated by salicylic acid (SA). Indirect-ELISA was used to detect TMV virus content,and the extent of resistance to TMV was studied by half-leaf method in lesion host. The results showed that the content of TMV in Nic-otiana tabacum decreased after induced by SA. With the time extending of TMV inoculation, the content of TMV increased and was up to maxim value at 28 d post-inoculation. The lesion number of tobacco leaves treated by SA was similar to those untreated upper leaves and was less than the control.
