Abstract

Potato virus Y (PVY) potyvirus leads to considerable potato production losses in Egypt and around the world. The PVY isolate confirmed by DAS-ELISA, (Solanum tuberosum) mechanically sap inoculated with PVY isolate under greenhouse condition, Thus Salcylic Acid, Spermine and Zinc Sulphate were verified as foliar treatment for induce the systemic acquired resistance in Solanum tuberosum L. Bellini plants against PVY. In accordance with this study, when compared to virus-free plants, PVY infection dramatically reduced photopigments and biochemical components (proteins and carbohydrates) but boosted bioactive components (phenols and proline) and antioxidant enzymes (POX, PPO, and SOD). In contrast, compared to the control plants, tested salcylic acid, spermine, and zinc sulfate shown a significant rise in all validated parameters. So it can determine three inducers Solanum tuberosum L. Bellini resistance against PVY but Zinc Sulphate treatment more than the other treatments.Potato virus Y (PVY) potyvirus leads to considerable potato production losses in Egypt and around the world.
