Leaf economic spectrum (LES) traits are considered to be the most important plant functional traits, greatly influencing element cycling and ecosystem processes. Mycorrhizal features are considered as part of the root economic spectrum constituting the whole plant economic spectrum, and thus probably linked to LES. Arbuscular mycorrhizas (AMs) are one of the most abundant symbiotic associations in nature, however, the relationship between the global LES traits and AMs remains unknown. Here, based on the global leaf traits database, 1037 plant species with ascertained mycorrhizal types are classified into arbuscular mycorrhizal (AM) and nonAM groups in order to explore the differences in LES traits between AM and nonAM plants. Results show the worldwide LES traits are greatly linked with mycorrhizal traits. For all plants, LES traits vary greatly, but AM plants display larger variations in the six LES traits than nonAM species. AM woody plants, especially trees, have shorter leaf lifespan (LL), lower leaf mass per area (LMA), and higher leaf nitrogen concentration (N_mass), photosynthetic capacity (A_mass) and dark respiration rate (R_mass) than nonAM woody ones, but similar leaf phosphorus concentration (P_mass). However, the LES traits of herbaceous plants showed no significant correlation with AMs. Compared to nonAM plants, more AM plants tend to adopt a "quick investment-return" strategy. In most cases, LES traits correlate significantly, but their interrelationships vary with mycorrhizal traits. In conclusion, AM plants possess highly varied LES traits and preference for a "quick" strategy, leading them to a high responsiveness to environmental challenges.

叶片经济谱（LES）性状被认为是最重要的植物功能性状，极大地影响了元素循环和生态系统过程。菌根特征被认为是构成整个植物经济谱系的根源经济谱系的一部分，因此可能与LES相关。丛枝菌根（AMs）是自然界中最丰富的共生协会之一，但是，全球LES性状与AMs之间的关系仍然未知。在此，根据全球叶片性状数据库，将确定的菌根类型的1037种植物分为丛枝菌根（AM）和nonAM组，以探讨AM和nonAM植物之间的LES性状差异。结果表明，全世界的LES性状与菌根性状密切相关。对于所有植物，LES的性状差异很大，但是AM植物比非AM物种在六个LES性状上表现出更大的变异。AM木本植物，特别是树木，具有较短的叶片寿命（LL），较低的单位面积叶片质量（LMA）和较高的叶片氮浓度（N_质量），光合能力（A_质量）和暗呼吸速率（R_质量）比非AM木本植物高，但叶磷浓度（P_质量）相近。然而，草本植物的LES性状与AMs无显着相关性。与非AM工厂相比，更多AM工厂倾向于采用“快速投资回报”策略。在大多数情况下，LES性状具有显着相关性，但它们之间的相互关系因菌根性状而异。总之，增材制造植物具有多种多样的LES性状和对“快速”策略的偏爱，从而使其对环境挑战具有较高的响应能力。
