“…The mature goldenrod leaves were harvested from Zhenjiang (32.16°N, 119.53°E), China in September 2018. The climate conditions of Zhenjiang were provided in our previous reports (i.e., the annual mean temperature: ≈16.1ºC; the annual precipitation ≈1,150.6 mm; the annual sunshine time: ≈1,986.9 h) [5,6,9,33]. The collected goldenrod leaves were washed adequately and air-dried thoroughly at approximately 25ºC.…”

“…SGeSGrP experiments of lettuce were executed using the incubation method in the Petri dishes in mid-January 2019. The incubation method of lettuce in Petri dishes was provided in our earlier studies [8,9]. The amount of germinated seeds (radicle exposed) of lettuce was recorded per day after incubation.…”

“…After eight days of incubation, ten lettuce seedlings of lettuce per Petri dish (i.e., fifty seedlings of lettuce per bioassay treatment group) were chosen randomly to assess SGeSGrP parameters of lettuce, namely, germination percentage (represents the germination ability) [3,9,10,13], germination potential (represents the germination capacity and uniformity) [3,9,10,13], germination index (represents the germination speed and vitality) [37][38][39], germination rate index (represents the germination speed and vitality) [40][41][42], germination vigor index (represents the germination speed and vitality) [39,43,44], promptness index (represents the robust response capability of seedling's germination) [45][46][47], seedling height (represents the competitive ability for sunlight acquisition) [3,9,10,13,33], root length (represents the competitive ability for water and inorganic salt acquisition) [3, 9, 10, 13], leaf length and width (represents the competitive ability for sunlight acquisition) [3,6, 8-10, 13, 33, 48], green leaf area (represents leaf photosynthetic area) [49][50][51], singleplant fresh and dry weights (represents plant growing ability) [3,9,10,13,24,33,48] and plant moisture content (represents plant water content) [3,9,10,…”

“…For instance, the allelopathy of the infamous IAS Solidago canadensis L. (goldenrod) occupy a decisive position in the process of effective establishment and flourishing expansion as well as the finally successful invasion [2, 8-10, 12, 13]. This fact is even more important as the allelopathy employed by IAS observably suppressed seed germination and seedling growth performance (SGeSGrP) of indigenous species [2,[8][9][10][12][13][14]. SGeSGrP constitute the core competence of plant life history, which determines the success of subsequently growth performance of the individuals and recruitment potential of the population [1,14].…”

Invasive alien species (IAS) can distinctly inhibit seed germination and seedling growth performance (SGeSGrP) of indigenous species via the allelopathy. The progressively increased drought stress can potentially affect the allelopathy of IAS. Thus, it is significant to illustrate the allelopathy of IAS on SGeSGrP of indigenous species under drought stress to obtain a deeper elucidation for the main driving mechanism attributed to the successful invasion. This study attempts to identify the allelopathy of IAS Solidago canadensis L. (goldenrod; using leaf extracts) on SGeSGrP of the indigenous species Lactuca sativa L. (lettuce) under drought stress [mimicked by Polyethylene glycol-6000 (PEG 6000)]. Goldenrod leaf extracts (low concentration) obviously reduced seed germination performance of lettuce but goldenrod leaf extracts (high concentration) notably reduced seedling growth performance of lettuce. Goldenrod leaf extracts (low concentration) also interestingly awarded an optimistic effect on the competitive ability for sunlight acquisition as well as water and inorganic salt acquisition, plant growing ability, and plant water content of lettuce. PEG 6000 dramatically inhibited the competitive ability for sunlight acquisition as well as water and inorganic salt acquisition of lettuce. PEG 6000 also noticeably enhanced the allelopathy of goldenrod leaf extracts on the germination speed and vitality, competitive ability for sunlight acquisition as well as water and inorganic salt acquisition, leaf photosynthetic area, and plant growing ability of lettuce. Thus, drought stress may be advantageous to the advance of goldenrod invasion process mainly via the oppressed SGeSGrP of indigenous species mediated by the enhanced allelopathy.

“…Moreover, a number of previous studies have reported that the allelochemicals released by these weeds to the surrounding environment can directly or indirectly inhibit the biomass production and yield of cultivated crops [ 18 , 21 ]. For example, Erigeron canndensis presents strong competition to food crops in terms of growth and also produces phytotoxic chemicals that can suppress the growth of cultivated crops [ 22 , 23 , 24 , 25 ]. Earlier studies have indicated that the allelopathic properties of weeds play an important role in the invasive and adaptative capacities of perennial broad-leaved and grass weeds in cultivated fields [ 26 ].…”

There is increasing interest in the application of bioherbicides because they are less destructive to the global ecosystem than synthetic herbicides. Research has focused on reducing the dependence upon synthetic herbicides by substituting them with environmentally and economically sustainable bioproducts. Allelopathic phytochemicals may be an efficient method for controlling weeds, benefitting both the environment and human health. This study addressed the allelopathic potential of Miscanthus sacchariflorus (MS) extracts on the germination, plant growth, biomass, and biochemical parameters (electrolyte leakage, photosynthetic pigments, and antioxidant enzyme activities) of weeds using laboratory and field experiments. Liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) showed the presence of 22 phenolic compounds, including Orientin, Luteolin, Veratric acid, Chlorogenic acid, Protocatechuic acid, p-Coumaric acid, and Ferulic acid. Leaf extracts of M. sacchariflorus either completely suppressed or partially reduced seed germination and affected the development of weed seedlings (root and shoot length), in a dose-dependent manner. Aqueous extracts of M. sacchariflorus reduced the fresh weight and dry weight, affected the photosynthetic pigment content (chlorophylls, carotenoids), influenced the electrolyte ion leakage, and stimulated the activity of antioxidant enzymes in a species-specific manner. Pearson’s correlation analysis showed that the phenolic compound composition of M. sacchariflorus correlated with the variables tested, indicating that the phytochemicals present in the plant extracts of M. sacchariflorus are a potential source of bio-herbicides.

Solidago canadensis L., native to North America, is now an invasive plant worldwide. Its abundant seeds, rapid vegetative reproduction ability, and allelopathy to other plants are the main reasons for its successful invasion. It has negative impacts on the ecological environment of the invaded area and causes a reduction in local biodiversity and economic losses of agriculture and stock farming. Each part of the plant contains a variety of allelochemicals (terpenoids, phenolics, and flavonoids), including a large number of essential oil components. These allelochemicals can be released in various ways to inhibit the growth of adjacent plants and promote their invasion; they can also affect soil properties and soil microorganisms. This article summarizes the allelopathic effects of S. canadensis on other plant species and the interaction mechanism between it and the ecosystem.
