Abstract: (381 Views)
Grapevine fanleaf virus (GFLV) is one of the most important and destructive grapevine viruses worldwide. The virus is a genus Nepovirus and is transmitted by the Xhiphinema index nematode. The present study was conducted to investigate the effect of salicylic acid foliar application on the incidence of GFLV on grapevine (Vitis vinifera L.) plants in the Faculty of Agriculture of Shiraz University in greenhouse conditions in 1398. Treatments included spraying as pretreatment and simultaneous application of salicylic acid and virus (SA + GFLV) on the leaves of biennial seedlings of white seedless cultivar in three concentrations of 50, 100 and 150 mg / l. Seedlings sprayed with potassium phosphate (without virus and salicylic acid treatment) were considered as controls. Comparison of the data mean to the effect of treatments on infected samples with GFLV showed that the highest and lowest disease progression were related to control and salicylic acid spraying before treatment with the virus, respectively. Analysis of physiological parameters showed that viral contamination and salicylic acid treatments affected cellular metabolism such as levels of pigments and proteins. The results of this study showed that the application of different concentrations of salicylic acid significantly increased the protein content of white seedless grapes. In addition, peroxidase activity and plant proline content were induced by virus inoculation simultaneous and post salicylic acid treatment. Therefore, salicylic acid treatment increased plant resistance to GFLV. The results of this study showed significant changes in metabolism and production of secondary metabolites in the plant under the influence of GFLV viral infection with salicylic acid treatments.
