Other claims from this paper (8)

Intervention effect Mexican sunflower extract significantly suppressed rice germination and growth, especially at higher concentrations.
Observation Abnormal seedling percentage was the most sensitive response to the extract, with IC50 = 5.59%.
Observation Radicle length had an IC50 of 7.82% for the Mexican sunflower extract.
Observation Plumule length had an IC50 of 8.81% for the Mexican sunflower extract.
Intervention effect At 10% extract concentration, plant height and leaf area were notably reduced.
Intervention effect At 10% extract concentration, chlorophyll content was notably reduced.
Intervention effect At 10% extract concentration, biomass was notably reduced.
Intervention effect Radicle growth was more affected by the extract than plumule growth.
