Orchardgrass and bermudagrass samples, collected in Virginia during the spring and late summer (mid-April to late August) will be analyzed for fructan content. Fructans will be extracted from the samples with boiling water and analyzed by anion-exchange high-performance liquid chromatography (HPLC) coupled to pulsed amperometric detection (PAD). Profiles will be compared to those of a sample harvested at the optimal growth stage to determine how seasonal and diurnal variations affect the relative changes in amounts and types of fructans in the forages.
