摘要:

近年来迅速发展的微树芯技术(micro-sampling approach)通过每周采集树干木质部的微样芯, 并制作生物切片来实时监测整个生长季的树干形成层细胞分裂活动以及木质部的形成过程。与传统的树木年轮学方法相比, 微树芯技术能从一个更微观、更准确的角度探索树木内在生理过程及树木生长对外界环境的响应。该文概述了微树芯技术的发展历程和应用前景, 并结合国内外研究来阐述利用树木微树芯技术研究树木初级生长和次级生长及其关系, 以及在全球变化(升温、干旱以及碳、氮增肥效应)背景下树木年内径向生长的响应机制, 为进一步预测森林生产力和固碳潜力以及实现可持续林业经营管理的政府决策提供科学依据。

Abstract:

The recently developed micro-sampling approach has been widely used to extract micro-tree-cores at weekly intervals to monitor the process of stem cambial activity and xylem formation. Compared with the traditional dendrochronology, the micro-sampling approach enables us to better understand the inherent physiological processes in tree growth and their relationships with the environment at a more precise level. This review article aims to: 1) summarize the progresses in the micro-sampling approach-based studies published over recent years and its potential applications, and 2) elucidate the relationships between primary growth and secondary growth and the response mechanisms of radial growth of trees to global change (global warming, drought, and carbon and nitrogen fertilization effects) based on information from literature. It is anticipated that this review will assist with predicting productivity and carbon sink potential of forests, and help policy-makers with sustainable forest management decisions.

Key words: micro-sampling approach, radial growth, xylem, cambium, climate change
