Interpretive Summary: Squash vein yellowing virus (SqVYV) is the cause of viral watermelon vine decline. In this study, watermelon plants of different ages were inoculated with SqVYV to characterize the physiological response to infection and provide new insights into watermelon vine decline.

Technical Abstract: Squash vein yellowing virus (SqVYV) is the cause of viral watermelon vine decline. In this study, watermelon plants of different ages were inoculated with SqVYV to characterize the physiological response to infection and provide new insights into watermelon vine decline. Physiological responses to SqVYV infection included reduction in plant fruit weights, alterations in fruit rind and flesh color, reduction in fruit sucrose content, increase in fruit acid content and changes in plant nutrient composition. More severe symptoms were observed in younger plants.
