The experiment was conducted at the facilities of Campus Montecillo in the Colegio de Postgraduados, Mexico. Seeds of two cultivars of jamaica (<em>cv</em>. Creole and <em>cv</em>. Spider) inoculated with cells of six bacterial strains (M83, M67, M88, L168, M82_A and M82_C), which were planted and grown in a greenhouse to determine: stem length (SL), root length (RL), dry root biomass (DRB), chlorophyll content (CHC), number of leaves (NL), stem diameter (SD) and radical volume (RV). The implemented experimental design was completely random blocks with a factorial arrangement (4 x 2 x 2 x 2). The concentrations of CuSO<sub>4</sub> used in the sowing were 10<sup>-2</sup> molar concentration (M) for the <em>cv</em>. Creole and 10<sup>-6</sup> M for the <em>cv</em>. Spider. The type of soil was decisive because it caused significant differences in most of the variables evaluated, except in the RL, DRB and RV. Inoculation with bacterial strains caused inhibition in the growth of SD in the <em>cv</em>. Spider at 80 days after sowing (das). The strains that promoted the plant growth of roselle were M83, M67 and M82 used in both cultivars. It is concluded that the roselle plants had no negative effects due to the stress condition caused by CuSO<sub>4</sub>. In general, the cultivar that had a greater tolerance to CuSO<sub>4</sub> was <em>cv.</em> Creole, therefore, could be considered as an alternative for phytoremediation of soils contaminated with wastewater.</p>}, number={29}, journal={Nova Scientia}, author={Khalil Gardezi , Abdul and Romero Andablo, Kenia Nallely and Carrillo Castañeda, Guillermo and Flores Magdaleno, Héctor and Flores Gallardo, Hilario and López Buenfil, José Abel and Ortega Escobar, Héctor Manuel and Escalona Maurice, Miguel Jorge and Larque Saavedra, Mario Ulises and Haro Aguilar, Gabriel}, year={2022}, month={Sep.} }
