| hanges in the nonstructural carbohydrate (NSC) levels in grain sorghum, Sorghum bicolor (L.) Moench, due to greenbug, Schizaphis graminum (Rondani) feeding were examined. Plants in the seedling, vegetative and reproductive growth stages were grown in laboratory, greenhouse and field conditions. Concentrations of fructose, glucose, sucrose, fructan, and starch in greenbug-infested and uninfested sorghum plant samples were determined using high performance liquid chromatography. Greenbug feeding altered concentrations of NSCs in sorghum plants for each plant growth stage. For seedling sorghum plants grown in the laboratory, greenbug infestations reduced shoot length, shoot fresh weight, shoot dry weight, root fresh weight, and root dry weight (df = 3, P... |
