In order to the beneficial effects of fulvic acid and iron in the improvement of growth and flowering characteristics of plants, in this research, the effect of fulvic acid and iron nano chelate was investigated on morphological and physiological characteristics of Gerbera cv. Dune. This experiment was conducted as a factorial based on a completely randomized design with two factors fulvic acid with 4 concentrations of 0 (control), 50, 100 and 250 mg/L as drench and iron nano chelate at 4 concentrations of 0 (control), 1, 2 and 4 gr/L as foliar application, with three replications in greenhouse conditions in pot and in hydroponic conditions. The treatments and interaction effects of fulvic acid and iron nano chelate increased measured indices compared to control. All of the treatments caused to increase leaf length significantly and petal anthocyanin compared to control. The highest leaf number (40 leaves) and leaf anthocyanin (8.37 µM/g F.W.) was observed in treatment of 250 mg/L fulvic acid and 4 g/L iron nano chelate. The highest rosette diameter (93.66 cm) was obtained in the treatment of 100 mg/L fulvic acid and 2 g/L iron nano chelate. The highest soluble sugar and guaiacol peroxidase enzyme activity were observed in the concentration of 250 mg/L fulvic acid or the concentration of 2 g/L iron nano chelate. For increasing catalase and ascorbate enzyme activity, 50 mg/L fulvic acid and 4 g/L iron nano chelate were the best treatments. In general application of fulvic acid and iron nano chelate in ornamental plants can have a positive effect on the plant.
