In their work with some native species, including Erythroxylum argentinum, Maraschin-Silva and Aquila (2006) noted significant increases in the hypocotyl development of lettuce seedlings when exposed to the leaf extract of E.
Maraschin-Silva and Aquila (2006) showed that the leaf extract of Erythroxylum argentinum also reduced the size of the primary roots of lettuce seedlings with increasing extract concentration compared with the control treatment.
The genus Erythroxylum is characterized by the presence of alkaloids of the tropane group, including cocaine, a natural alkaloid produced by E.
The allelopathic potential of the ethanolic extract of Erythroxylum leaves varies with the target species and was more evident in the seed germination and seedling development of Lycopersicum esculentum than in Allium cepa.
