Saffron is known as one of the most common spices and medicinal plant in the world. Little information is available on the effects of copper and growth regulators on morphological characteristics of saffron. The aim of this study was to evaluate the influence of different concentrations of copper and auxin on morphological properties of root and leaf of saffron. This study was arranged as a factorial experiment in greenhouse condition and in hydroponic system. Copper was used in copper sulfate (CuSO4) form (0, 0.02, 0.1 and 0.2 mg/L) and auxin in naphthalene acetic acid (NAA) form (0, 1 and 2 g/L). Results showed that interaction of Naphthalene acetic acid 1 g/L and copper sulfate 0.1 mg/L increased root number, as well as root and leaf dry weight. Furthermore, naphthalene acetic acid 1 and 2 g/L in most treatments reduced the number of buds. Copper concentration of corm was increased in 0.2 mg/L copper sulfate.
