摘要

树木的生长对水分缺乏非常敏感。同时,生长过程通过改变根系吸收面、叶片蒸腾面、传导木质部的数量等,对水分胁迫下树木的性能产生实质性影响。干旱引起的生长抑制在针叶树中往往比在阔叶树中更高。本文综述了北半球温带和寒带气候干旱化加剧条件下针叶植物生长与性能的关系。对于成树而言,现有证据表明,与生长对水分有效性不太敏感的树木相比,在有利条件下生长速度较快但在缺水条件下生长速度下降更明显的树木,水分亏缺的频率和严重程度的增加将更有害。不仅生长过程对供水的总体敏感性,而且对低于平均和高于平均湿度条件的响应的不对称性对即将到来的不利气候变化下针叶树的表现也很重要。为了充分了解树木在未来气候变化下的响应,需要分别分析树木对干旱年和湿润年的响应。在针叶树幼苗中,更活跃的生长通常与更好的干旱存活有关,尽管这种联系的生理原因可能不同。夏季水分亏缺加剧条件下,针叶植物的生长稳定性可以通过更活跃的春季生长和/或双峰生长模式来维持;每种策略都有特定的优点和缺点。增长战略的最佳选择对未来的再造林计划至关重要。

Linking the growth patterns of coniferous species with their performance under climate aridization

Linking the growth patterns of coniferous species with their performance under climate aridization

Tree growth is highly sensitive to water deficit. At the same time, growth processes substantially influence tree performance under water stress by changing the root-absorbing surface, leaf-transpiring surface, amount of conducting xylem, etc. Drought-induced growth suppression is often higher in conifers than in broadleaf species. This review is devoted to the relations between the growth of coniferous plants and their performance under increasing climate aridization in the temperate and boreal zones of the Northern Hemisphere. For adult trees, available evidence suggests that increasing the frequency and severity of water deficit would be more detrimental to those plants that have higher growth in favorable conditions but decrease growth more prominently under water shortage, compared to trees whose growth is less sensitive to moisture availability. Not only the overall sensitivity of growth processes to water supply but also the asymmetry in response to lower-than-average and higher-than-average moisture conditions can be important for the performance of coniferous trees under upcoming adverse climate change. To fully understand the tree response under future climate change, the responses to both drier and wetter years need to be analyzed separately. In coniferous seedlings, more active growth is usually linked with better drought survival, although physiological reasons for such a link can be different. Growth stability under exacerbating summer water deficit in coniferous plants can be maintained by more active spring growth and/or by a bimodal growth pattern; each strategy has specific advantages and drawbacks. The optimal choice of growth strategy would be critical for future reforestation programs.

期刊介绍: The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
