Soil biota can affect plant-plant interactions and non-native plant invasions via plant-soil feedback (PSF). Understanding the drivers underlying interspecific variations in PSF is important for predicting the role of soil biota in non-native plant invasions. Recent studies found that PSF could be predicted by plant traits. The success of plant invasions is also linked with plant traits, suggesting a potential linkage between PSF and plant invasion via plant traits, but has not yet been tested. Here, we compared PSF between six phylogenetically-paired co-occurring native and invasive plants, and explored the potential linkage between PSF with plant root traits.

细根/总根质量比的相似性导致同生天然植物和入侵植物之间植物土壤的比较反馈

土壤生物区系可以通过植物-土壤反馈（PSF）影响植物与植物的相互作用以及非本地植物的入侵。理解PSF种间变异背后的驱动力对于预测土壤生物群在非本地植物入侵中的作用非常重要。最近的研究发现，PSF可以通过植物性状来预测。植物入侵的成功也与植物性状相关，表明PSF和通过植物性状入侵植物之间存在潜在的联系，但尚未经过测试。在这里，我们比较了六种系统发育配对的天然植物和入侵植物之间的PSF，并探讨了PSF与植物根系性状之间的潜在联系。
