Thaís Paula Rodrigues Gonçalves; Lucas Santos Azevedo; Mariana Guerra de Aguilar; et al. Horticulturae 2026. doi:10.3390/horticulturae12010088

Other claims from this paper (5)

Intervention effect The HEX fraction significantly inhibited seed germination and root growth.
Intervention effect The DCM fraction significantly inhibited seed germination and root growth.
Intervention effect The EA fraction showed genotoxic potential at higher tested concentrations.
Intervention effect Extract and fractions reduced glyphosate-induced genotoxicity and reversed chromosomal abnormalities.
