“…S. canadensis was introduced to Shanghai, China, as a horticultural plant in the early 1930s. S. canadensis has become naturalized in most of China and recognized as one of the most destructive and widespread invasive species in the country [29][30][31]. Branch number, reproductive branch number, maximum length of branch, maximum angle of branch, frequency of reproductive investment, the amount of reproductive investment, and the coefficient of RA (C RA ) of the two plants are measured to characterize their RA strategy.…”

Plant invasion succeeds because of such invader characteristics as fecundity and high-efficiency multiple reproduction modes. The acquisition of individual resources and the benefits of individual fitness are driven by optimum patterns of life history and trade-offs of reproductive allocation (RA) in plants, and variations in RA strategy play an key role in plant adaptation to environmental changes. Thus determining the RA strategy of invasive plants is important for understanding the successful mechanism underlying plant invasion. This study aims to determine the reproductive allocation (RA) strategy of two herbaceous invasive plants (Conyza canadensis and Solidago canadensis) across different cover classes in eastern China. Plant height, maximum branch length, the reproductive branch number, aboveground biomass, the amount of reproductive investment, and the coefficient of RA of the two plants decreased with increasing cover class (although the changes were not pronounced). Thus the two plants may decrease physiological investment on reproductive behavior and reduce RA under competitive conditions because of interspecies competition that progressively decreased and intraspecific competition that gradually increased with increasing cover class. The RA of the two plants may be principally influenced by plant community composition at low cover classes, but by soil pH at high cover classes. This may be the outcome that soil pH of the two plants decreased with increasing cover class significantly. Thus, intraspecific competition for resources may play an important role in the RA strategy of the two plants under high cover class.

“…The results of this study have shown that the biochar had considerable adsorption capacity for DMP, which is identied as the typical allelochemical of Solidago canadensis. 2,22 The added biochar could act as a sorbent for the allelochemicals. Therefore, the inhibitory effect of allelochemicals on the tomato seeds was alleviated.…”

Solidago canadensis is a malignant invasive plant widely distributed in China. In this study, it was used as a biomass source to prepare biochar via an oxygen-limited pyrolysis method. The effect of temperature, heating rate and pyrolysis time on the yield and surface characteristics of the biochar was identified. The adsorption properties for dimethyl phthalate (DMP), a typical allelochemical of Solidago canadensis, of the biochar were explored. In addition, a pot experiment was conducted to reveal the effect of the biochar on tomato seed germination in the presence of allelochemicals. The maximum yield of the biochar was observed when Solidago canadensis was pyrolyzed at 300 C for 2 h, with a heating rate of 8 C min À1. Variation of pyrolysis conditions had little influence on the surface characteristics of the biochar. The adsorption of DMP on the biochar could be well described by the Langmuir model, with a maximum adsorption capacity of 59.37 mg kg À1. The addition of biochar to the soil could promote tomato seed germination in the presence of allelochemicals. Therefore, the biochar prepared from Solidago canadensis can be used for soil amendment for invaded sites.

“…Solidago canadensis L. (Asteraceae) is a rhizomatous clonal perennial forb native to North America that has invaded China (Dong et al., ; Xu et al., ; Zhao et al., ). In China, S. canadensis was first introduced to Zhejiang, Jiangsu, and Shanghai provinces in the early 1930s as an ornamental garden species (Xu et al., ; Zhao et al., ). It escaped from cultivation and experienced explosive spread after the 1980s and is now distributed widely across eastern China where it abounds in disturbed habitats including agricultural lands, roadsides, railways, and city suburbs (Dong et al., ; Zhao et al., ).…”

Premise Evolutionary adaptation may enable plants to inhabit a broad range of environments. However, germination and early life‐history stages have seldom been considered in estimates of evolutionary adaptation. Moreover, whether soil microbial communities can influence evolutionary adaptation in plants remains little explored. Methods We used reciprocal transplant experiments to investigate whether two populations of an invasive plant Solidago canadensis that occur in contrasting habitats of low versus high salinity expressed adaptation to the respective salinity levels. We germinated S. canadensis seeds collected from low‐and high‐salinity habitats under low‐ and high‐salt treatments. We also raised S. canadensis seedlings from the two salinity habitats under low‐ and high‐salt treatments and in the presence versus absence of microbial communities from the two habitats. Results Genotypes from a low‐salinity habitat had higher germination rates under low‐salt treatment than genotypes from a high‐salinity habitat. However, both genotypes had similar germination rates under a high‐salt treatment. The two genotypes also had similar seedling survival and biomass responses to low‐ and high‐salt treatments. Nevertheless, seedling biomass was significantly higher under low salt treatment. Soil microbial communities did not influence biomass of S. canadensis under the two salt treatments. Conclusions The results on germination rates suggest partial local adaptation to low salinity. However, there was no evidence of local adaptation to salinity at the seedling survival and growth stages. The finding that germination and seedling biomass responded to different salt treatments suggests that the two traits are important for salt tolerance.
