通过确定为什么某些植物或植物的一部分更难以释放糖来了解导致生物量不顺从的结构特征对于克服这一障碍非常有价值。考虑到这一点，本研究通过考虑两个山杨横截面的老化影响来研究木材的顽抗性。通过应用我们新颖的小规模系统，包括多孔预处理和酶水解系统以及缩小规模的成分分析程序，我们能够跟踪逐环成分和糖释放模式。然后将观察到的变化与树木径向方向上发生的结构变化相关联，这为理解这些变化对顽抗性的影响迈出了重要的一步。 (C) 2010 Elsevier Ltd. 保留所有权利。
Understanding structural characteristics that are responsible for biomass recalcitrance by identifying why it is more difficult for some plants, or portions of plants, to release their sugars would be extremely valuable in overcoming this barrier. With this in mind, this study investigated the recalcitrance of wood by considering the effects of aging in two Populus tremuloides cross sections. By applying our novel small scale systems, including a multi-well pretreatment and enzymatic hydrolysis system and a downscaled compositional analysis procedure, we were able to follow ring-by-ring compositions and sugar release patterns. Observed variations were then related to structural changes that occur across the radial direction of trees, providing an important step toward understanding the influence of these changes on recalcitrance.
