Demonstrates the inhibitory effects of Alternanthera philoxeroides extracts on Zinnia elegans, suggesting potential management strategies for invasive plants.
Key Points
This research aims to investigate how extracts from Alternanthera philoxeroides affect seed germination and growth in Zinnia elegans.
Analyzed aqueous extracts from stems, leaves, and roots of A. philoxeroides.
Utilized Petri dish filter paper method and pot experiments for germination tests.
Measured seed germination rates and seedling growth parameters at different concentrations (25, 50, 100 mg·mL−1).
Aqueous extracts significantly inhibited seed germination and seedling growth of Z. elegans.
High concentrations of stem and leaf extracts reduced germination rates by up to 99.10% and 90.65%.
Extracts induced oxidative stress in seedlings, with increased malondialdehyde and altered antioxidant enzyme activities.
