Hippeastrum hybridum is one of the tuberous ornamental plants that is distributed around the world. Regarding the cultivation of ornamental plants in landscaping, it is essential to use salinity-resistant ornamental species or induce resistance traits to these stresses through plant breeding and physiological methods. The experiment consisted of five salinity concentrations [control (distilled water) with EC=0dSm-1, and electrical conductivity (EC) at 2, 4, 6 and 8 dSm-1] with four replicas on leaf freshness, leaf length and width, proline, nitrogen (N), potassium (K), phosphorous (P) content, and peroxidase enzyme activity. Increasing salinity led to decreased leaf nutrients and growth parameters like plant height, shoot weight, leaf length, width, weight, and corm weight, and increased proline and peroxidase activity.
