迷你加速器已被证明对了解细根的动态和功能很有用。然而，它们在森林和其他自然植物群落中的使用相对较少。造成这种情况的因素有几个，包括沿微电子加速器表面的异常根部分布以及从微电子加速器图像中提取数据的困难。技术和方法的进步已经改善了其中的一些困难，微型加速器在解决一些长期感兴趣的问题方面具有相当大的潜力。这些问题包括更充分地了解根在碳和养分循环中的作用、根的分解速率、对资源可用性的响应以及植物根与土壤生物之间相互作用的功能意义。最大限度地发挥微型加速器的潜力，帮助我们更好地了解细根在天然植物群落中的功能重要性，取决于使用它们只回答那些适合它们固有优势和局限性的问题。
Minirhizotrons have proved useful to understand the dynamics and function of fine roots. However, they have been used comparatively infrequently in forests and other natural plant communities. Several factors have contributed to this situation, including anomalous root distributions along the minirhizotron surface and the difficulty of extracting data from minirhizotron images. Technical and methodological advances have ameliorated some of these difficulties, and minirhizotrons have considerable potential to address some questions of long standing interest. These questions include more fully understanding the role of roots in carbon and nutrient cycling, rates of root decomposition, responses to resource availability and the functional significance of interactions between plant roots and soil organisms. Maximizing the potential for minirhizotrons to help us better understand the functional importance of fine roots in natural plant communities depends upon using them to answer only those questions appropriate to both their inherent strengths and limitations.
