Variation of Some Plant Growth Parameters in Coriander (Coriandrum sativum L.) with Copper Application

This study was carried out to investigate the effect of different copper (Cu) concentrations on some plant growth parameters in coriander (Coriandrum sativum L.). The study was perfomed at the Agricultural Biotechnology growth room, Faculty of Agriculture, Siirt University (Turkey). In the study, the coriander Mardin province population was used as plant material. Five different doses of Cu (0, 100, 200, 300, and 400 ppm) were applied to plants. Plant height (cm), stem diameter (mm), the number of branches per plant, the number of umbel per plant, the number of seeds in the main umbel, plant fresh, and dry weights (g) were determined. According to the results, the effect of different Cu concentrations in all growth parameters except stem diameter and number of branches were found to be significant. In the current study, plant height, stem diameter, number of branches, number of umbel, number of seeds in the main umbel, and plant fresh weight and dry weights were ranged between 41.31-52.79 cm, 1.57-2.18 mm, 3.07-5.71 per plant, 2.57-4.86 per plant, 13.36-37.86 per plant, 2.33-4.12 g and 0.239-0.550 g, respectively. In the study, it was concluded that coriander can be included in phytoremediation programs in Cu-contaminated areas.
