Environmental gradients play important roles in shaping the diversity of functional traits of crops. Therefore, it is imperative to reveal how crops respond to environmental shifts. In this study, a ten-year investigation (from 2008 to 2018) of an important medicinal crop, dogwood (Cornus officinalis Sieb. et Zucc.), was conducted to reveal the effects of environmental shifts on crop functional traits and bioactive products. The C. officinalis plants originated from three main producing areas were cross-regionally introduced to study area. The key environmental factors of the three original regions (ORs) and the introduced region (IR) were monitored. The functional traits and bioactive products of C. officinalis were estimated. Furthermore, the correlations among functional traits, bioactive products, and environmental factors were analyzed. The results showed that there were significant differences between functional traits and bioactive products of C. officinalis in ORs and in IR (P < 0.01). Further correlation analysis showed that 100-fruit weight was negatively correlated with both average minimum temperature and average precipitation in March (P < 0.01). The changes of loganin content was positively correlated with those of average minimum temperature and average precipitation in March (P < 0.05). Collectively, the above findings indicate that environmental shifts (e.g., average precipitation in March) play important roles in C. officinalis bioactive products. The potential introduced regions with similar environment conditions are beneficial for yield and quality of C. officinalis. These results will provide valuable references for understanding the effects of climate change on functional traits and bioactive products of medicinal crops.

环境梯度在塑造农作物功能性状多样性方面起着重要作用。因此，必须揭示农作物如何应对环境变化。在这项研究中，对重要药用作物山茱dog（Cornus officinalis Sieb。et Zucc。）进行了为期十年的调查（从2008年至2018年），以揭示环境变化对作物功能性状和生物活性产品的影响。来自三个主要产区的C. officinalis植物被跨区域引入研究区域。监测了三个原始区域（OR）和引入区域（IR）的关键环境因素。山茱C的功能性状和生物活性产物被估计。此外，分析了功能性状，生物活性产物和环境因素之间的相关性。结果表明，药材中的C. officinalis的功能性状和生物活性产物在IRs和IR中存在显着差异（P <0.01）。进一步的相关分析表明，三月的平均最低温度和平均降水量与100个果实的重量呈负相关（P  <0.01）。3月份loganin含量的变化与平均最低气温和平均降水量呈正相关（P  <0.05）。总的来说，上述发现表明环境变化（例如3月的平均降水量）在Ç。巴戟生物活性物质。具有相似环境条件的潜在引入区域有利于C的产量和质量。厚朴。这些结果将为理解气候变化对药用植物功能性状和生物活性产品的影响提供有价值的参考。
