Two biotypes of the invasive species, Chromolaena odorata are known to be present in Africa, viz. the Asian/West African biotype (AWAB) and the southern African biotype (SAB). Although the phytochemistry, ethnomedicinal and ethnopharmacological relevance of the AWAB has been elucidated, the SAB...

This study aims to determine the allelopathic potential of Amaranthus retroflexus (Ar) with different climatic zones on seed germination and growth of A. tricolor (At) treated with a gradient N addition. Ar leaf extracts only displayed significantly allelopathic potential on the underground growth...

Although transport of oxygen via the aerenchyma tissue and subsequent oxygen loss across root surfaces is well-documented for salt marsh grasses, only few studies have measured the oxygenation of sediment surrounding roots and rhizomes. In this study, sediment oxygenation was assessed in situ in...

Xanthium spinosum is a noxious invasive weed that is spreading throughout Xinjiang Province. This plant threatens ecological safety, biodiversity, and agricultural development in affected areas. Because X. spinosum has shown strong adaptation to the divergent environment in the Hi River valley,...

Alternanthera philoxeroides is a perennial invasive species worldwide which can greatly affect native ecosystems and agricultural production. Our research studied the allelopathic effects of aqueous extracts of A. philoxeroides on the growth and antioxidant enzyme activities of Zoysia matrella, and ...

To explore the effect of Galinsoga parviflora Cav., an invasive plant on seedling growth and photosynthetic physiological characteristics of broad bean (Vicia faba L.), the pot experiments were conducted to study the effects of plant heights, leaf areas, biomass, chlorophyll contents, chlorophyll...

Background: Astragaloside IV (AS-IV), the major active triterpenoid in Radix Astragali, has shown anti-tumorigenic properties in certain cancers; however, its role in breast cancer remains unclear. The present study investigated the effects of AS-IV on breast cancer in vitro and in vivo and...

β-Carboline alkaloids of the harmala group (HAlks) - a family of compounds with pharmacologic effects - can be found at trace levels (<25 µg kg^-1 algae) in the edible invasive algae Undaria pinnatifida, known commonly as wakame. In this study, we present a simple and sensitive method to detect...

This study aimed to examine the allelopathic potential of Eucalyptus and Calotropis species on seed germination and seedling growth of Acacia ehrenbergiana (Hayne), Acacia gerrardii (Benth.) and Acacia tortilis (Forssk.). The aqueous leaf extracts of Eucalyptus camaldulensis var. obtusa (Blakely), ...

Knotweed is an invasive plant that creates high compact growth when uncontrolled that can suppress the growth of native plants and thus reduce biological diversity. These invasive plants contain many antioxidants that require identification and quantification. In this work, aqueous 2% acetic acid,...
