Description

Abstract: Peanuts (Arachis hypogaea L.), cultivar Florunner, from plants inoculated with peanut stripe virus (PStV) were evaluated for chemical composition in comparison with peanuts from uninoculated plants. At harvest, seed were collected from plants which had been mechanically inoculated with PStV at emergence, or 20, 40, or 60 days after emergence and from uninoculated plants. The seed from PStV-infected plants had increases in manganese, selenium, zinc, iron, tartaric acid, raffinose, glucose, fructose, and total carbohydrate Contents as compared to seed from uninoculated plants. Sucrose was increased in seed from plants inoculated with PStV at time of emergence. There was a decrease in the concentration of potassium, magnesium, protein, and total soluble phenolics of seed from plants inoculated with PStV. There were no changes in the concentration of stachyose, inositol, phosphorus, sulfur, calcium, copper, and oil.
