Parthenin is a metabolite of Parthenium hysterophorus and is believed to contribute to the weed's invasiveness via allelopathy. Despite the potential of parthenin to suppress competitors, low doses stimulate plant growth. This biphasic action was hypothesized to be auxin-like and, therefore, an...

Invasive plants can affect native plants through competition or allelopathy, and researchers often use pot experiments as a tool to measure the strength of these interactions. Recently, such pot experiments provided inconsistent estimates of the impact and allelopathic potential of invasive...

Invasive species can exhibit allelopathic effects on native species. Meanwhile, the types of acid deposition are gradually changing. Thus, the allelopathic effects of invasive species on seed germination and growth of native species may be altered or even enhanced under conditions with diversified...

Non-native plant invasions can suppress biodiversity and alter ecosystem functions, but often the mechanisms underlying the impacts of invasions are unknown. We used a greenhouse mesocosm experiment and a growth chamber germination experiment to evaluate the competitive and allelopathic effects of ...

Non-native plant species may contain allelopathic substances that might help to out-compete native vegetation. These allelochemicals may be released from live or dead plant tissues and be accumulated in the soil. We tested whether non-native species leaf litter and their leachates reduced seedling...

This study aims to evaluate the allelopathic activity of Bambusa vulgaris Schrad. ex J.C. Wendl., invasive species in an area of Cerrado in the Chapada do Araripe in Ceará. The treatments consisted of the aqueous extract in concentrations of 25, 50, 75 and 100% and a Control (distilled water), with ...

Essential oils have the potential to be used as bioherbicides, and possess the advantage of their biodegradability, high structural diversity and reduced natural resistance to weeds. The essential oils of the leaves and rhizomes of Hedychium coronarium, an exotic invasive plant adapted to different ...

Background and Aims: Allelopathy may drive invasions of some exotic plants, although empirical evidence for this theory remains largely inconclusive. This could be related to the large intraspecific variability of chemically mediated plant-plant interactions, which is poorly studied. This study...

Hyptis suaveolens is an exotic invasive weed in many areas of West Bengal, India. The allelopathic potential of leaf extracts and leachates of H. suaveolens was investigated on germination and metabolism of mung bean seeds (Vigna radiata cv. K851). The extracts and leachates reduced the germination ...
