“…Soil from all pots within the three variants was mixed to create specific soil types (see Hawkes et al 2013 andSun et al 2014 for similar approach). We mixed the soils because we wanted to study the overall effects of native and invasive populations of R. austriaca, rather than looking at the effect of individual genotypes or populations, and we wanted to keep the number of replicates reasonable.…”

Background and aims Although plant-soil feedback has been suggested as a mechanism that drives the success of invasive plants, studies that investigate differences in the intensity of plant-soil feedback among native and invasive populations of the same species are still lacking. However, such knowledge is important because it can provide an understanding of the mechanisms responsible for the spread of a species. Rorippa austriaca is a potentially invasive species -a successful range expander in Europe.Methods We compared the plant-soil feedback of R. austriaca in populations from its native and invasive range. We explored both intraspecific feedback as well as feedback on a co-occurring grass species. Results Our results revealed a strong negative feedback effect as a consequence of soil conditioning by R. austriaca from the native range. On the contrary, a negative feedback effect was not observed for invasive R. austriaca. Interestingly, R. austriaca from the invasive range had a higher biomass than native R. austriaca. Conclusion Our results might be explained by pathogen accumulation and soil modification by native R. austriaca, which had strong intra-and interspecific effects that seemed to be lost in the invasive R. austriaca. The loss of negative intraspecific plantsoil feedback and the increased growth of the invasive population may contribute to its successful range expansion. In spite of its increased growth, the co-occurring grass species is expected to successfully coexist with the invasive R. austriaca.

“…Allelopathy, microorganisms and nutrients most closely relate with the performance of plants among all the abiotic and biotic factors of soil (Bonanomi et al, 2005;Manning et al, 2008;Sun et al, 2014). In this study defined as a negative soil feedback on productivity of monospecific Chinese Pearson's correlation coefficients (r s ) are calculated by pairwise comparison with Chinese fir root dry weight and soil microbial properties including MBC and PLFA, root dry weight and soil nutrients, root dry weight and soil allelochemical cyclic dipeptide as well as total phenolics.…”

“…It is clear that allelochemical context affects the performance of plant and alters the soil microbial community (Macias et al, 2004;Bonanomi et al, 2005;Zhang et al, 2011;Sun et al, 2014). Therefore, it will be realistic to discuss the root behavior in the context of allelochemicals.…”

“…Of these interactions, microbial degradation and persistence of allelochemicals are crucially important factors for the action of allelochemicals in soil (Macias et al, 2004;Teasdale et al, 2012;Li et al, 2013). In particular, allelochemical-induced specific alteration in the soil microbial community may result in a positive or negative feedback effect on plant growth and reproduction (Bonanomi et al, 2005;Bezemer et al, 2006;Sun et al, 2014). However, relatively little is known about tree-derived allelochemicals and their impacts on the soil microbial community and root growth in long-term monospecific forest plantations.…”

“…An increasing number of studies have shown that allelopathic rice cultivars release allelochemicals to interfere with the growth and establishment of coexisting barnyardgrass . Through the release of allelochemicals, allelopathic rice cultivars can suppress barnyardgrass and provide a competitive advantage for their own growth . It can be assumed that allelopathic rice interferes with the growth of herbicide‐resistant barnyardgrass.…”
