Effects of C isotope-labeled allelochemicals on the growth of the invasive plant Alternanthera philoxeroides.

The secondary metabolites of indigenous plants have significant allelopathic inhibitory effects on the growth and development of invasive alien plants. Methyl palmitate (MP) and methyl linolenate (ML) were used as exogenous allelopathic substances. The research investigated the differences of inhibitory effects of MP and ML on the growth of seedlings of Alternanthera philoxeroides, and calculated their morphological characteristics, biomass, physiological indicators and the response index (RI).

Effects of simulated acid rain on rhizosphere microorganisms of invasive and native .

Acid rain not only has serious harm to the environment, but also has the same threat to plants, but the invasive plant still grows well compared to the native plant under acid rain stress. However, the underlying mechanism of resistance to the acid rain environment in invasive remains unclear. In the current study, we comparatively analyzed the plant physiological characteristics, soil physicochemical properties, and rhizosphere microbial communities of invasive .
