Chemical analysis studies were conducted for four populations of switchgrass (Alamo, Kanlow, GA993, and GA992), Panicum virgatum L., which were partitioned into leaves, internodes, and nodes. The variations in carbohydrate compositions, lignin and extractives content, higher heating value (HHV), and the syringyl:guaiacyl ratio of switchgrass were determined. The experimental results indicated that bulk chemical profiles for the four populations of switchgrass were comparable. However, the results from three morphological components of switchgrass, leaves, internodes and nodes, provided a significant diversity among the analytical results studied.
对四种柳枝稷（Alamo、Kanlow、GA993 和 GA992）进行了化学分析研究，这是一种帕尼姆草属植物，分为叶片、节间和节点。测定了柳枝稷的碳水化合物组成、木质素和抽提物含量、高位热值（HHV）和愈创木基：苯丙烷比率的变化。实验结果表明，四种柳枝稷的总体化学特征相似。然而，柳枝稷的三个形态成分（叶片、节间和节点）的结果表明，在研究的分析结果之间存在显著的差异。
