地下性状的最优分区理论是否失效？从苏格兰松树林干旱释放实验的地球物理成像中获得的启示。

我们在一片自然干旱的苏格兰松树林中研究了 20 年灌溉对根系吸水（RWU）和干旱应力释放的影响。我们结合使用了电阻率断层扫描技术对 RWU 进行成像，无人机飞行对树冠压力进行成像，以及传感器对土壤含水量进行监测。我们的研究结果表明，水分供应的增加能促进根系生长和资源利用效率，通过从更深的土壤层吸收水分，有可能增强树木对未来干旱条件的抵抗力。这项研究强调了生态记忆和遗产效应在决定树木对环境变化的反应方面的重要作用。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
