Analysis of the development of seedlings of the species Chenopodium ambrosioides L. subjected to growth regulators in different concentrations Gilberto Rodrigues Liska1 Alexandre Alves de Carvalho2 José Eduardo Brasil Pereira Pinto3 Augusto Ramalho de Morais4 Guido Gustavo Humada5 The demand for medicinal plants, among them the Chenopodium ambrosioides, has increased lately. Therefore, there is need for methods to accelerate the development of these seedlings.
